Turn iPhone 15 Pro Max into a 5G High-Speed Router

Joey — Mon, 13 Nov 2023 01:32:26 +0000

Introduction

After switching to a USB Type-C physical port in the iPhone 15 series, accessories like docks and hubs originally designed for iPad and MacBook devices can also be used with the new iPhone. In fact, we tested the iPhone 15 Pro series and found that it can indeed connect to hubs with Ethernet ports, allowing for high-speed and stable wired networking. You can click here to have a look.

As Apple's official website states, all models in the iPhone 15 series come equipped with 5G connectivity and gigabit LTE technology. This raises a question: if the iPhone 15 Pro series can "receive" high-speed networks, can it also "provide" high-speed networks? In other words, can it become a high-speed mobile router in areas with full 5G signal coverage? Let's find out!

Product Introduction

First, let's provide a brief introduction to the iPhone 15 Pro Max. It retains a design almost identical to its predecessor, featuring a "dynamic island" design on the front, with improved border size and smoothly rounded screen edges. Furthermore, it maintains a 6.7-inch display.

The "Silent" button on the left side has changed to a touch button.

Only the 15 Pro and 15 Pro Max have that sweet USB 3.2 Gen 2, which can achieve speeds of up to 10Gbit per second.

Network Speed Test

First, we used a SIM card with activated 5G network service in the iPhone 15 Pro Max.

After inserting the SIM card and powering on the phone, the 5G UI in the notification bar displays full signal strength.

We used a capable consumer-grade network speed test application to test the phone's network speed. The download speed reached 520Mbps, while the upload speed was limited to 87Mbps due to the carrier's restrictions.

5G High-Speed Router

Now, we will turn the iPhone 15 Pro Max into a mobile high-speed router to provide network connectivity to other devices such as Android phones, tablets, and laptops, simulating everyday internet usage and software downloads.

First, we need to enter the "Cellular Data Options" in the phone's settings and select "Allow More Data on 5G." This is to ensure the best performance and avoid performance losses due to the phone's battery and mobile network policies.

Next, we turn on the phone's personal hotspot, and it's advisable to enable the "Max Compatibility" option to share the network via Bluetooth, USB, and other methods.

Using the mentioned software, we tested the Xiaomi 13 Ultra's download speed in a wireless connection, and it reached 62.61Mbps.

We also downloaded a random game on the Xiaomi 13 Ultra, and the download speed in the notification bar showed around 8.6MB/s, with an overall speed fluctuating around 10MB/s.

Similarly, whether it's a tablet or a laptop, these devices can access the internet using the phone's "5G speed" hotspot.

We conducted network speed tests via speedtest.net on a MacBook. And after multiple node changes, the download speed fluctuated around 120Mbps.

In terms of the internet experience, when the phone serves as a mobile hotspot, tablets and laptops experience minimal network fluctuations causing lag while browsing web pages and watching videos. Overall, the interface loading and display speed are comparable to a 100Mbps broadband experience, surpassing the experience of a 4G network hotspot.

However, it's a bit disappointing that when the iPhone 15 Pro Max is used as a "5G high-speed router" and connected to smartphones via a USB-C cable, it doesn't allow the connected devices to access the internet. This is a missed opportunity, considering the 10Gbps USB-C port on the iPhone 15 Pro series.

The same limitation applies to tablets.

However, laptops are an exception and can access the internet through a USB-C cable, with download speeds fluctuating around 240Mbps. Of course, this feature has been available on both old iPhones and Android phones for a long time and is quite useful for desktop computers.

Summary of ChargerLAB

Based on our testing of turning the iPhone 15 Pro Max into a "5G high-speed router," we found that in areas with 5G signal coverage, this phone's network speed can reach over 500Mbps. This essentially meets the network speed requirements for 5G communication, but actual results may vary due to the complex signal transmission conditions in different regions and environments.

Furthermore, when other devices such as phones, tablets, and laptops connect to the "5G high-speed router," their internet download and content display are faster, surpassing the experience of a 4G network SIM card. However, when sharing the network using a USB-C cable, only computers can enjoy this feature.

The following year, Samsung abandoned its conventional naming conventions and went straight to the S20 Series. Samsung explained that "we chose Galaxy S20 because we wanted a name that kicks off the next ten years of innovation". The most significant feature of this series was the upgrade to 5G. There were substantial improvements in charging as well. The S20, S20+, and S20 Ultra had battery capacities of 4000mAh, 4500mAh, and 5000mAh, respectively. In terms of charging power, the first two supported 25W, while the latter could be charged at a remarkable 45W. It's important to note that the Ultra model came with a standard 25W charger, and to utilize the 45W charging, an additional purchase was required.

Reduced to 25W - Galaxy S21 Series

In January 2021, the Samsung S21 Series was released. Only the S21+ saw an increase in battery capacity from the previous generation, reaching 4800mAh. Interestingly, the charging power of the ultra model regressed to 25W in this generation. Additionally, following in Apple's footsteps, no models in this series included a power adapter.

Slight Improvement - Galaxy S22 Series

In this generation, the ultra model's battery capacity remained the same, while the S22 and S22+ saw reductions to 3700mAh and 4500mAh, respectively. However, the ultra model reintroduced the 45W charging power.

Environmentally Friendly - Galaxy S23 Series

The Samsung Galaxy S23 Series is currently the most environmentally friendly among Samsung's Galaxy lineup, featuring the highest use of recycled materials. In this series, the S23+ also saw an upgrade to 45W charging. In terms of batteries, the Galaxy S23 featured a 3900mAh battery, the Galaxy S23+ had a 4700mAh battery, and the Ultra model remained unchanged.

The above chart summarizes the key specs of the Samsung Galaxy S series. Clearly, as time goes by, mobile phone chips become more powerful, and features become richer. This not only increases power consumption but also makes more people rely on their phones, which naturally leads to larger batteries. As early as February 2020, the Galaxy S20 series introduced a substantial 5000mAh battery, which remains the largest battery capacity in the Galaxy S series to date.

We have also ranked the battery capacities of all models for your convenience. You can see that the Galaxy S series' largest battery capacity is 5000mAh, found in the Galaxy S Ultra model, which is a whopping 3500mAh larger than the original Galaxy S.

Furthermore, over the course of more than a decade of development, the capacities of the 29 different models mentioned were entirely sufficient for their respective times. However, it's important to keep in mind that these capacities should only be considered for analysis and reference, as they may not directly compare with today's standards.

Summary of ChargerLAB

The variation in battery capacities within the Samsung Galaxy S series reflects a broader trend in the current smartphone market. To meet consumers' demands for longer battery life, an increasing number of smartphone brands are introducing high-capacity battery phones. This trend is not limited to the Samsung Galaxy S series; it's evident in other smartphone brands as well.

It's worth noting that while high-capacity battery phones dominate the Galaxy S series, it doesn't imply that there's no market for lower-capacity battery phones. For example, in the past two years, Samsung released the Galaxy S22 and Galaxy S23 with batteries below 4000mAh. Some users may prefer lighter and more portable phones and may not require extensive battery life. By appropriately enhancing the charging speed on these phones, manufacturers can cater to a wider range of user preferences and buying needs.

Experience Better Network Connectivity with iPhone 15's USB-C Port

Joey — Mon, 06 Nov 2023 01:37:31 +0000

Introduction

As we all know, the first iPhone series to support 5G is the iPhone 12 series. In the specific specs, it is clearly labeled as "supports Gigabit LTE with 4x4 MIMO and LAA." However, in reality, more recent iPhones, especially since the iPhone X, have had mediocre signal performance. While it may achieve downstream bandwidth of up to 1Gbps in specific situations, this speed is rarely reached in everyday use. Furthermore, even when connected to WiFi, the wireless connection's limits and stability can't match a wired connection.

That's where the USB-C hub with an Ethernet port comes into play. With the new USB-C port, the iPhone 15 series, especially the Pro and Pro Max models, can now enjoy USB-C hubs. They offer more options and are more affordable than Lightning port hubs. So today, we'll test the download speed of the iPhone 15 Pro Max when connected to a wired network.

The USB-C Ports of The iPhone 15 Series

It's important to note that the base model of the iPhone 15 series and the Pro series have different USB-C ports.

The USB-C port on the iPhone 15 and 15 Plus still uses the USB 2 standard, with a maximum transfer rate of 480Mbps.

Only the 15 Pro and 15 Pro Max have that sweet USB 3.2 Gen 2, which can achieve speeds of up to 10Gbit per second.

Expanded Test

First, while the iPhone 15 series can't directly connect to Ethernet cables with RJ45 connectors, it can be used with USB-C hubs that have RJ45 Ethernet ports.

Furthermore, when using a USB-C hub with the iPhone 15 Pro Max, you can charge the device, screen mirror, and even use a wired mouse and keyboard. We may demonstrate these functions in detail in the future, so stay tuned!

As shown in the image, the UGREEN 6-in-1 USB C Docking Station we have on hand can connect to the iPhone 15 Pro Max, allowing you to use a keyboard, mouse, USB drive, and Ethernet cable without any compatibility issues.

With these steps, you can easily turn your iPhone 15 into a simple office hub, suitable for some simple tasks like document writing and video calls.

In a gigabit network environment, using a capable consumer-grade professional network speed test application, the iPhone 15 Pro Max achieves a download speed of nearly 900Mbps and an upload speed of 100Mbps when connected via Ethernet, showcasing its gigabit-level network transmission capability.

Furthermore, to minimize the influence of external factors, the phone was disconnected from Wi-Fi and cellular networks during the test. Personally, I found that when downloading everyday communication apps and games, connecting via a gigabit Ethernet connection was faster and produced less heat.

As shown in the image, when downloading large games and their updates on the iPhone 15 Pro Max, the process is almost instantaneous, reducing waiting times to a minimum.

Moreover, all four of the new iPhones, including the iPhone 15 Pro Max, can play your favorite games via a wired network, offering a more stable network environment than Wi-Fi or cellular data. Additionally, they support screen mirror and peripherals like keyboards and mice.

Summary of ChargerLAB

In summary, the USB-C port equipped in the iPhone 15 series opens up endless possibilities for their expandability when using a USB-C hub. These hubs provide users with the ability to enjoy a stable and high-speed wired network connection, ideal for tasks ranging from document writing to online gaming. Through our test, we observed that the iPhone 15 Pro Max, when connected via Ethernet, demonstrated remarkable downlink speeds and minimized the impact of external factors, resulting in faster downloads and reduced heat generation during intensive tasks.

However, beyond the improved network performance, there are additional benefits worth mentioning. Wired connections offer enhanced security and reliability, reducing the possibility to interference. This makes them ideal for activities requiring a stable and secure internet connection such as data-intensive tasks.

From 30-Pin to USB-C: A Port Journey of the iPhone

Joey — Tue, 24 Oct 2023 01:34:39 +0000

Introduction

Since the release of the first iPhone in 2007, spanning over 16 years, Apple has launched a total of 42 iPhone models. In a previous ChargerLAB analysis, we examined the battery capacities of each iPhone generation. To sum it up, the iPhone with the largest battery capacity (iPhone 15 Pro Max) had 3272mAh more capacity than the smallest (iPhone 3G), which is equivalent to an additional iPhone 15 Pro's worth of battery capacity. That's quite crazy!

When it comes to port types, the recent shift to a USB-C port in the iPhone 15 series is undoubtedly good news for users. But this leads to the question: how long will Apple continue to use USB-C in iPhones? Is there a pattern to Apple's port changes? Today, we will attempt to analyze this by summarizing the charging ports used in Apple products from the original iPhone to the iPhone 15 series.

30-Pin Dock Connector

For gen Z, it might be unfamiliar, but the 30-Pin Dock Connector was originally introduced with the 3rd generation iPod classic all the way back in 2003. In 2007, Apple introduced the iconic original iPhone, marking the first appearance of this connector on an iPhone. Interestingly, due to the large number of pins, two pins of this connector were never used until it was replaced by the Lightning port.

The 30-Pin Dock Connector served in Apple phones for nearly five years, and in Apple's early products, it performed its duties well. It had a multitude of pins and supported the native USB 2 protocol, allowing the iPhone to perform various USB 2 functions without requiring a conversion chip. It could handle various protocol connections, audio, and video analog signal outputs. However, it had one fatal flaw – it was too large, and Apple urgently needed a more advanced port.

Lightning

Fast forward to September 12, 2012, when Apple introduced the brand new Lightning port in a special event at the Yerba Buena Center for the Arts in San Francisco. This day marked the official replacement of the 30-Pin Dock Connector that Apple had used for nine years, and it was around five years of service in iPhones.

Compared to its predecessor, the greatest advantage of the new port was its 80% reduction in size. This allowed for more internal design space within the phone, and it made the iPhone 5, the first device to feature the Lightning port, the "lightest iPhone ever" according to Apple. The new port had symmetrical 8-pin contacts on both sides, meaning it could be inserted either way. Apple claimed that the Lightning port was not only easier to use but also more durable and versatile. Starting in 2017, it introduced PD fast charging protocols for iPhone 8, 8 Plus, and X, further enhancing its capabilities.

Initially, the Lightning port became synonymous with advanced charging. However, with the release of the USB-C port, which also supported reversible insertion and offered superior performance, things began to change. Specifically, the Lightning port, designed for its compactness, ease of use, and simplicity, had only 16 pins in total. In contrast, the USB-C port has 24 pins. This limitation meant that the data transfer rate of the iPhone was capped at the USB 2.0 level. Additionally, due to the fact that only one pair of contacts was used for power delivery, the Lightning port had limited current-carrying capacity. Therefore, despite the addition of fast charging technology, Apple could only provide low-power charging. All these inconveniences led to increasing calls within the tech industry for Apple to replace the Lightning port, and the time for a change had come.

USB-C

In the 2023 Apple Fall Event, Apple finally introduced the highly anticipated iPhone 15 series with a USB-C port. The adoption of the USB-C port marked the end of Apple's ten-year history with the Lightning port. Since the USB-C port is now widely used in the world of Android smartphones and various tech products, this change ended the hassle for Apple users who previously needed to carry at least two cables while on the go. It also effectively reduced electronic waste, aligning with Apple's recent strong push for environmental sustainability.

The more versatile USB-C charging port allows for charging iPhones, Macs, iPads, and the new AirPods Pro (2nd generation) with just one cable. Moreover, this USB-C port supports reverse charging, enabling users to charge AirPods or Apple Watch directly with an iPhone, enhancing the overall user experience. However, it's worth noting that this is not a new feature in the Android world. The USB-C port on the Pro version takes things further, supporting USB 3.0 and achieving data transfer speeds of up to 10 Gbps.

Summary of ChargerLAB

In terms of quantity, among the 42 iPhone models released by Apple from iPhone 2g to the iPhone 15 series, a staggering 33 models featured the Lightning port. This is more than three times the combined total of 30-Pin Dock Connector and USB-C port models, generating significant profits for Apple.

To sum it up, before the introduction of USB-C, the relatively advanced and less flawed Lightning port served in iPhones for 11 years. USB-C, with its greater pin count and versatility, is likely to match or even surpass this record. However, this port is not perfect. For instance, in charging setups that use the USB-C port, the more delicate connector is undoubtedly on the charging device's side, such as the phone or tablet. This means that if this connector becomes damaged, the replacement can only be the more expensive devices like phones or tablets. How long it will continue to exist in iPhones? Only time will tell.

Maintaining iPhone 15 Battery Health with This Tip

Joey — Sun, 22 Oct 2023 00:46:00 +0000

Introduction

Previously, Apple unveiled the new iOS 17 at WWDC 2023. ChargerLAB has tested the StandBy mode under the beta system and provided a detailed overview and operation guide, which interested individuals can find here. After updating to the new system, ChargerLAB noticed that there are more options in the Charging Optimization within the battery settings of the iPhone 15 Pro Max. Curious about what we discovered? Let's find out!

Speaking of battery health, it's worth noting that Apple actually increased the battery replacement service fees globally in 2023. Specifically, the out-of-warranty battery service fee increased by $20 for all iPhone models before the iPhone 14. Today, we'll explore a discovery that might further extend battery life.

Enabling the Settings

Upon opening the iPhone 15 series settings, you'll notice a difference in the "Battery Health & Charging" option regarding Charging Optimization.

Compared to the iPhone 14 Pro Max, Charging Optimization is no longer a simple on/off switch but has been transformed into a multi-choice menu.

Clicking into the menu, you'll find the familiar "Optimized Battery Charging" that has been around since iOS 13, but there's also a new addition - "80% limit." In fact, we tested this during our upcoming iPhone 15 Pro charging review. However, the battery level in that test still exceeded the "80% limit," reaching 81% or more. Let's see if the latest version still exhibits this issue.

Charging Test

Next, we'll use the Apple 35W Dual USB-C Traditional Power Adapter to fully charge the iPhone 15 Pro Max with the Optimized Battery Charging setting on.

As shown in the charging curve graph, once the battery reaches 80%, the charging speed significantly decreases until it reaches 100%. Although not shown in the graph, we confirmed that this also applies when charging optimization is turned off.

Moving on to the "80% limit" option, when the battery is at 70%, the charging power is around 16W, similar to the other two options at this time point.

The UI displays the battery level as 80%, and the phone continues to charge.

However, at this point, the power drops significantly to 1.21W, providing just enough energy to sustain the phone in standby.

Three minutes later, the battery level remains at 80%.

Avoiding Extreme Temperatures

It is widely known that devices with built-in batteries should be kept from being charged or discharged for extended periods in very hot or cold environments. This can affect the movement of lithium ions and may permanently damage the battery's capacity, reducing its overall lifespan.

In fact, Apple's official website provides rather detailed temperature range recommendations for different smart devices. Storing batteries in environments with excessively low or high temperatures can potentially result in irreparable damage. Under normal circumstances, when the battery exceeds the recommended temperature range, the software may restrict charging after reaching 80% capacity.

Additionally, using a protective case or wireless charging may generate excessive heat and impact the battery's health. We previously made a MagSafe charging comparison for the iPhone 14 Pro Max with or without a case, which you can check it out.

Summary of ChargerLAB

This test was performed using the latest system version, and unlike the initial test, the phone did stopped charging at around 80% this time. It's worth noting that it took Apple about two weeks to resolve the overheating issue with iOS 17.0.2. Hopefully, in the future, Apple will thoroughly check for such major user experience-affecting bugs before releasing system updates, and iOS will return to being known for its stability and user-friendliness.

This new battery optimization feature can help users avoid overcharging during nighttime, thereby extending the battery's lifespan. Although this feature doesn't allow users to set their own charging limits at the moment, it should be sufficient for the needs of most typical users.

What is GaN Exactly? - ChargerLAB Explained

Joey — Tue, 17 Oct 2023 01:35:27 +0000

Introduction

GaN charger is the most frequently mentioned word in our website. We‘ve taken apart many GaN chargers. However, many people may not know what GaN is. Let us talk about it today.

GaN is the abbreviation of Gallium nitride. It's a compound of nitrogen and gallium and is well-known as a third-generation semiconductor material.

The structure is similar to wurtzite (zinc and iron sulfide mineral) with high hardness.

It also has a very wide band gap of 3.4 eV (electron volts) and can be used in high-power, high-speed optoelectronic components.

If you look at it from the outside, you will find that it's generally like yellow powder.

It can produce chemical reactions when exposed to water and is non-flammable.

The compound was first synthesized in 1928. After 70 years of continuous development, it was widely used in diodes in the 1990s.

The performance of GaN switch transistors is much better than that of silicon-based switch transistors, which is mainly reflected in the following five aspects:

1. Higher breakdown voltage

2. Faster switching frequency

3. Lower on-resistance

4. Higher thermal conductivity

5. Lower switching losses

Furthermore, it can be grown on a variety of substrates, including sapphire, silicon carbide (SiC), and silicon (Si).

So, it can achieve higher efficiency, higher power density, or even both after replacing silicon components with GaN components.

For now, GaN components are widely used in many fields. For example, GaN semiconductors can be used in military electronics industry. It's now the first choice for producing large-scale search radars for fighter aircraft.

And it can also be used in base stations. The higher energy efficiency, wider bandwidth, higher power density, and smaller size make it ideal for next-generation base stations, especially in the frequency band above 1.8GHz.

In the field of optoelectronics, GaN is used to make LEDs and lasers. GaN can be mixed with indium (InGaN) or aluminum (AlGaN) to create LEDs with colors ranging from red to ultraviolet. And the GaN-based violet laser diodes are used to read Blu-ray discs.

But in ChargerLAB, what we are most concerned about is how it is used in chargers.

It's not very long for GaN components to be used in chargers. Back in 2014, Navitas, which was just founded, launched the world's first GaN power IC prototype. In 2018, it was first adopted by Anker in their chargers.

Then, more and more manufacturers began to do so, and even Apple launched its first 140W GaN charger.

So how does GaN allow chargers to significantly reduce size and increase output power?

First, we need to understand how the charger works.

In most cases, the transformer is the largest component in the charger. When the output power is fixed, its size is directly related to the frequency of the pulsed current, that's "f". When the voltage (U) remains unchanged, if we want to reduce the size, that is, reduce the cross-sectional area (S).

The best way is to increase the frequency (f).

And switch transistor can control the frequency. In the process of continuous switching, the GaN switch transistor can reach higher frequencies than the silicon transistor. The loss is lower and the heat dissipation efficiency is higher. So, the charger and transformer can be smaller than before.

The charger is just a device that can convert high-voltage AC into low-voltage DC.

Switching transistors are the most common components in chargers. When used with capacitors and inductors, they can be used in rectifier circuits, buck circuits, and PFC circuits.

The primary MOSFET and PFC MOSFET are gradually being replaced by GaN components. Some chargers also adopt GaN components to replace synchronous rectification MOSFET, like the Anker GaNPrime series. The synchronous buck MOSFET and VBUS MOSFET may also be gradually replaced by GaN components in the future.

Summary of ChargerLAB

In conclusion, GaN (gallium nitride) has revolutionized charger technology with its efficiency and compactness. As we look to the future, GaN is poised to play a central role in charger applications, promising even faster charging and smaller form factors. However, the relentless pace of innovation suggests that there may be more advanced materials on the horizon, waiting to take GaN's place. While GaN has certainly left its mark, the charger landscape is an evolving one, and we can anticipate exciting developments in the quest for more efficient and sustainable power solutions.

Navigating Plug Standards for International Explorations with ChargerLAB

Joey — Tue, 05 Sep 2023 01:35:47 +0000

Introduction

As the global COVID-19 pandemic gradually recedes, the worldwide tourism industry is making a comeback. The enchanting landscapes and diverse cultures of foreign lands have always been alluring. However, the various plug specifications and standards around the world can be perplexing. Different plug regulations exist within individual regions and even between countries.

Taking Europe as an example, the term "Euro-plug" we often hear isn't uniform. Although it mostly refers to type C, there are also type E, type F, and type G plugs, each suited for different countries and regions. The sheer number of standards across the world makes it challenging for hassle-free travel. Today, we'll focus on this topic and delve into knowledge about international standard plugs.

Background

One might wonder why a unified global plug standard isn't established. Such a standard would benefit travelers with cross-border needs and simplify the management of plug-in devices for different countries, reducing e-waste. The advantages are numerous.

However, the reality is that there are significant differences in power systems between countries. These differences directly lead to the adoption of standards and schemes that fit their own power systems for the configuration and design of electrical devices. In addition to power system disparities, an essential factor is the varying safety standards and certifications for electrical devices. This divergence contributes significantly to the myriad of charging equipment standards.

Differences in Power Systems

Currently, countries around the world commonly adhere to different voltage and frequency standards. By voltage distinction, there are two categories: low voltage, ranging from 100 to 130V, and high voltage, ranging from 220 to 240V.

The graphic above summarizes the different power standards worldwide. In general, countries emphasizing energy efficiency tend to adopt high voltage and low frequency. For example, most European countries and China employ a voltage of 220-240 volts and a frequency of 50 hertz, while safety-focused countries like the United States and Canada use 110 volts and a frequency of 60 hertz. Such disparities can render electrical devices incompatible between countries, necessitating adapters or converters to adjust voltage and frequency.

Differences in Safety Standards

Different countries have varying safety standards and certification requirements for electrical devices. For instance, Europe uses the CE mark as a safety certification, while the United States employs UL certification. These certification requirements cover the design, materials, manufacturing, and safety performance of electrical devices, ensuring compliance with local safety standards. Below are common international certification symbols:

Apart from this, symbols and warning signs used on electrical devices may also differ between countries. These indicators convey characteristics, safety precautions, and usage instructions for electrical devices. Therefore, understanding the meanings of these symbols and signs is crucial during international travel or when using appliances across different countries.

Common Standards

As mentioned earlier, there are various specifications for international standard plugs, categorized into two-pronged and three-pronged (with grounding) based on the grounding requirement. They can also be classified by the appearance of the prongs, such as flat, round, and hybrid types.

The common appearances of standard plugs worldwide are illustrated in the graphic above, showcasing significant design differences.

EU Standard

The European standard plugs refer to the types of plugs widely used in the European region. Below is an introduction to the main European standard plugs.

European standard two-prong plug type C: This is the most common plug type in Europe. It features two round prongs without grounding. Typically used for small electrical devices like phone chargers and small kitchen appliances. It's widespread in parts of Europe, Africa, and Asia, including countries like France, Germany, Italy, and the Netherlands.

Type E: Widely used in France, it has two roundprongs and an additional grounding prong, with a slightly different shape compared to type C. Primarily used for large appliances like televisions and refrigerators. Apart from France, it's used in countries like Belgium and Monaco.

Type F: Commonly used in Germany, it also has two round prongs and a grounding prong, similar to the two-prong type in France (type E) but with minor differences. Type F plugs are also prevalent in countries like Austria, the Netherlands, and Indonesia.

US Standard

The United States and Canada use similar standard plugs collectively known as the US standard, which includes the following two types:

US standard two-prong plug type A: This is the most common plug type in the United States and Canada. It features two flat parallel prongs without grounding. It is commonly used for small electrical devices like phone chargers and small kitchen appliances. Widespread in the United States, Canada, Mexico, and some Central and South American countries.

Type B: With two flat prongs and an additional grounding round prong, type B is used for larger appliances like televisions and refrigerators, providing secure connections for devices requiring grounding protection. Found in the United States, Canada, and other regions, it caters to the safety needs of appliances.

UK Standard

The UK standard three-prong plug type G: Common in the UK and several other countries, it features three rectangular prongs, two of which are of equal height, while the third is slightly shorter and used for grounding.

Type G plugs include a grounding function, providing a safer power connection. These plugs are used for larger appliances and critical household items like televisions, computers, and refrigerators.

Due to well-known reasons, type G plugs are widely used in the UK, its territories, and related countries. Apart from the UK mainland, they're also used in countries and regions like Malaysia, Singapore, Hong Kong, Ireland, Cyprus, and Malta.

AU Standard

Similar to many other countries, Australia's standard plugs come in both two-pronged and three-pronged varieties.

Australian standard three-prong plug type I: Commonly used in Australia and New Zealand, it features three flat prongs, two of equal height and the third slightly shorter, used for grounding to ensure a safer power connection. This plug type is typically utilized for large appliances and household items such as televisions, computers, and refrigerators.

Australian standard two-prong plug: Part of Australia's AS/NZS 3112 standard and a type I plug, the only difference from the three-prong version is the absence of the grounding prong. It is commonly used for small electrical devices like phone chargers and electronics. Both these plug types are extensively used in Australia, New Zealand, and their territories.

Others

In addition to the commonly used national standard plugs mentioned above, there are distinctive plugs in other countries.

For example, Italy and Chile adopt the three-prong round plug type L. Apart from these, there are many other countries with unique plug types not listed here.

Adapters and Converters

In the landscape of diverse global plug standards, plug adapters/converters come as essential tools for international travel. They bridge the gap between different countries' plug standards and voltage specifications.

Plug Adapter

A plug adapter is a simple electrical accessory used to convert your device's plug into one that fits the socket standard of your destination country. It doesn't alter voltage; its purpose is to address the mismatch in plug shapes.

For example, if your device has a US type A plug, but you're traveling in Europe, you can use a plug adapter to convert the type A plug to type C, allowing your device to fit into the local socket and function normally.

Voltage Converter

A voltage converter not only adapts plugs but also adjusts the voltage of your electrical devices. This is particularly useful when there are different voltage standards in various countries.

For instance, the standard voltage in the US is 110 volts, while in Europe, it's 220-240 volts. If you're taking devices from the US to Europe, a plug adapter can solve the socket mismatch, but the voltage difference might damage your devices or prevent them from working correctly. In such cases, a voltage converter is needed to adjust your device's voltage from 110 volts to 220-240 volts, aligning with the target country's voltage standard.

Standardization Efforts

Given the current situation, plug standardization is an important developmental trend to address the differences in power plugs across countries and regions. International organizations have been working diligently to push for the establishment of unified standards. Furthermore, emerging technologies and innovations are also propelling the development of plug standardization.

Organizations

Organizations dedicated to promoting plug standardization include the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

ISO and IEC are two international standardization organizations committed to creating international standards, including those for electrical plugs. Through the collaboration of these organizations, it's hopeful that different countries and regions will develop consistent plug standards, promoting interoperability and safety of global electrical devices.

Additionally, many regions have established regional standardization organizations, such as the European Committee for Electrotechnical Standardization (CENELEC) and the American National Standards Institute (ANSI). These organizations assist in formulating regional electrical plug standards to meet local needs and requirements.

Wireless Charging Technology

Innovations in power transmission technology can also significantly impact the standardization of international plugs, even triggering revolutionary technological changes.

The advancement of wireless charging technology could lead to changes in plug standards, potentially introducing more standards based on wireless charging. This would allow devices to be charged without the need for physical plugs and sockets. As a result, traditional plugs and sockets might become obsolete in scenarios involving wireless charging.

Summary of ChargerLAB

In general, given the current differences in power systems and safety standards among countries, the trend of each country maintaining its own plug specifications is unlikely to change significantly in the short term. Travelers with international travel needs should still understand the local electrical equipment standards to avoid unnecessary hassles.

However, the good news is that the market for multi-country power adapters and converters is rapidly evolving. Not only are there abundant options, but their performance is also becoming more robust, and compatibility with various international standards is increasing. This is of paramount importance for lightening the load of international travelers.

Furthermore, international efforts to unify plug standards are gaining momentum, and the emergence of new technologies is driving standardization toward unity. Some regions, like the European Union, are already leading the way in plug standardization. Presently, type C plugs are widely used in EU countries.

What Is HDMI and How Does It Works?

Introduction

In recent years, various handheld game consoles have appeared on the market, such as Steam Deck, ASUS, Switch, etc, and there is a new type of charger with an HDMI port for handheld game consoles. We took apart HAGiBiS 65W and Baseus 67W before, you can click on the links to check them. And today, we want to introduce what HDMI is and how it works to you.

I believe you have seen it on TVs, monitors, and notebooks.

Versions

It was first released in December 2002 by TV manufacturers, like Hitachi, Panasonic, Philips, Sony, and Toshiba. And it was designed specifically for the era's Blu-ray technology, and its primary feature was the simultaneous integration of video and audio transmission. In comparison to the single video transmission of DVI and DP at that time, it was better suited for audiovisual equipment. It had a maximum bandwidth of 4.95Gbps, with 3.96Gbps allocated for video streaming, supporting resolutions of 1080P or 1600*1200. On the audio side, it supported 8-channel LPCM 24bit/192kHz.

HDMI 1.1 was released in May 2004, adding support for DVD audio based on 1.0.

HDMI 1.2 was released in August 2005 and the bandwidth reaches 4.95Gbps.

It supports super audio CDs and solved the low resolution and poor compatibility of HDMI 1.1.

HDMI 1.3 was released in June 2006, doubling the bandwidth to 10.2Gbps. The cable consists of four pairs of transmission channels, with one pair serving as the clock channel, while the remaining three pairs are designated as TMDS channels (Transition Minimized Differential Signaling). And the color depth is greatly expanded to 30 bits, 36 bits, and 48 bits.

The HDMI 1.4 was released in May 2009 and is the most popular version, because this is the first time the HDMI supports 4K video. And the ARC (Audio Return Channel) makes it possible for HDMI-connected TV to send audio data to the audio output devices, like soundbar. Additionally, it has also introduced a new 100Mbps network transmission capability.

HDMI 2.0, also known as "HDMI UHD," was introduced in September 2013. This iteration saw a bandwidth upgrade to 18Gbps, enabling support for 4K resolution at 60Hz refresh rate. It introduced features like hot plugging and audio support for up to 32 channels, with a maximum sampling rate of 1536kHz.

In terms of compatibility, HDMI 2.0 doesn't replace previous versions but ensures backward compatibility with earlier generations. However, despite these advancements, HDMI 2.0 is not as widely adopted as its predecessor, HDMI 1.4, at present.

And the latest version of HDMI is 2.1, which was released in January 2017. The bandwidth was greatly increased to 48Gbps, faster than Thunderbolt 4.

It supports up to 8K 60Hz or 4K 120Hz, and many new features have been supported, like dynamic HDR, eARC, Dolby Atmos, etc.

Types

After introducing different versions of HDMI from 1.0 to 2.1, let's take a look at different types of HDMI connectors.

Like USB-A, USB-B, USB-C, there're five types of HDMI connectors, from Type-A to Type-E.

Standard Type-A is the most common connector in our daily life.

With 19 pins, a width of 13.9mm (0.55 inches), and a thickness of 4.45mm (0.18 inches), it offers compatibility ranging from HDMI 1.0 to 2.1.

Type-B is pretty rare, as you can see we only got this low resolution image for you.

It has 29 pins and can support high-resolution video of 2560×1600 theoretically, but the HDMI chip at that time could not support it, so it gradually faded away.

The Type-C is known as mini HDMI connector, which was released after HDMI 1.3.

It also has 19 pins, but adopts a single-row design.

The small size makes it suitable for some notebooks or portable displays.

The Type-D is about half smaller than Type-C, called micro HDMI connector.

It was released after HDMI 1.3 and adopts a double-row 19-pin design. We can find this kind of port on cameras, tablets. However, let's be honest, those who have used it know that it can be considered one of the most prone-to-failure interfaces out there

Finally, the Type-E is specially designed for vehicles, which is very rare. And the locking tab can keep the stable connection.

It also has 19 pins.

Furthermore, the suitability of an HDMI cable for real world usage is contingent upon both its "cable" and "connector" components. The cable determines the bandwidth, which translates to the highest supported resolution, while the connector determines the types of devices it can connect to. Based on varying data bandwidths, HDMI cables are categorized into four specifications: Standard, High Speed, Premium High Speed, and Ultra High Speed. The data bandwidth ranges from a starting point of 2.25Gbps to a maximum of 48Gbps.

So, you may find that different types of HDMI connectors can support different types of HDMI versions. We cannot distinguish which video formats it supports from the appearance of the HDMI connector. That's pretty similar to USB-C connector.

Features

After discussing the connector types, let's delve into its special feature: HDCP (High-bandwidth Digital Content Protection). Developed primarily by Intel, this technology aims to prevent users from illegally recording content and protect copyrights. When unauthorized recording is detected, HDCP can reduce the video quality and resolution.

If you've ever noticed that your screen recordings appear blurry, this could very well be the reason.

HDMI vs DP

There's another universal connector for video signal transmission, the DisplayPort. So, what's the difference between HDMI and DP?

As mentioned, HDMI was initiated by TV manufacturers and adopts the TMDS method for transmitting data. After the image is converted by graphics card, it needs to be transmitted to the display line by line.

But the DP was initiated by PC manufacturers, and the image does not need to be converted. It directly packs the images generated by the graphics card into small data packets, known as micro packets, and directly transmits them to the display.

So, the transmission performance of DP is much better than HDMI. The latest DP2.0 can achieve a single output of 16K 60Hz or dual output of 8K 120Hz and supports HDR-10, and the HDMI 2.1 only supports up to 8K 60Hz.

Summary of ChargerLAB

Well, that's a brief introduction to the HDMI standard.

As the most widely used audio and video standard, each new version will bring larger bandwidth, wider color depth, and richer functions.

However, there is not only one competitor in this market. Perhaps in the future, the HDMI, DP, USB4, and Thunderbolt 4 will be integrated into the USB-C connector. We only need a USB-C full-function cable to enjoy a better user experience with different standards.
