Rusell — Tue, 28 Jan 2025 01:00:00 +0000

Introduction

In September, the iPhone 16 series was released, along with the new MagSafe that can support 25W. The appearance has not changed much; it is thinner and lighter, and the cable has been replaced with a woven cable. Next, let's take a look at its charging performance.

Product Appearance

It comes in a white box with the Apple logo and product appearance.

There is a product usage diagram printed on the back, and it has passed CE certification.

The specs info is posted on the bottom of the box: length 1m, model: A2580.

The box contains the MagSafe charger and some documents. It uses a woven cable, and the magnetic module is smaller and thinner.

It can support input of 5V3A, 9V3A, and 15V3A.

The USB-C connector is printed with New Zealand R-NZ and Japan VCCI certification logos.

The model and serial number information is printed here.

It adopts the non-full pin design.

A close look at the woven cable.

The length is about 104 cm (3' 4.94'').

The diameter of the wireless charging panel is about 55.38 mm (2.18 inches).

The thickness is about 4.53 mm (0.18 inches).

The wire diameter is about 2.35 mm (0.093 inches).

The weight is about 46.1 g (1.63 oz).

The left side is the old MagSafe (A2140), and the right side is the new 25W MagSafe (A2580). They are the same in appearance; the main difference is the cable material.

The top one is the new 25W MagSafe, and the bottom one is the old MagSafe.

The new 25W MagSafe is thinner than the old MagSafe.

Wireless Charging Test

In addition to supporting 25W MagSafe charging, the iPhone 16 Pro Max also supports Qi2 15W wireless charging and Qi 7.5W wireless charging.

Using an Apple 30W charger and the new MagSafe Charger to charge the iPhone 16 Pro Max, the measured input power is about 14.96V 1.94A 29.03W. Excluding losses, the wireless charging power is about 25W.

Full Charging Test

Next, we'll use the MagSafe Charger with an Apple 30W charger to fully charge the iPhone 16 Pro Max. And put them into a 25°C (77℉) thermotank throughout the test.

The voltage is around 15V at first, and the charging curve can be divided into five parts. In the first part, the peak power stays at 29W for the first 5 minutes. Then, the power gradually drops to 21W, 10W, and 4W in turn. At 39 minutes, the voltage drops from 15 V to 9 V briefly and then increases to 15 V. At 55 minutes, the voltage drops from 15 V to 9 V. The final part begins at one hour and 16 minutes; the power slowly drops to almost zero. During this process, the voltage drops to 5V. It takes 2 hours and 23 minutes to be fully charged.

We also turn it into another curve. The new MagSafe Charger can charge the iPhone 16 Pro Max to 50% in 34 minutes. And it can reach 80% in 1 hour and 10 minutes and 100% in 2 hours and 23 minutes.

Temperature Test

Since wireless charging generates a lot of heat, temperature is something everyone is concerned about. So, we recorded the highest temperature on the front and back after charging for 15 mins, 30 mins, and 50 mins.

After 15 mins of charging, the maximum temperature of the contact surface between the phone and the wireless charger is 41.2℃ (106.16 ℉). At this time, the charging power is about 21W.

After 30 mins of charging, the maximum temperature is 39.4℃ (102.92 ℉).

After 50 mins of charging, the maximum temperature is 39.3℃ (102.74 ℉). At this time, the charging power is about 10W. Compared with the temperature at the 15th minute, the temperature dropped by about 1.9°C, but it was still relatively high.

Summary of ChargerLAB

The new 25W MagSafe uses a woven cable, which is more durable. Compared to the old model, it is thinner.

Within 31 minutes, the new MagSafe Charger can maintain a charging power of 21 to 29W. The full charging time is 2 hours and 23 minutes, which is similar to the previous generation. As for the temperature, it was maintained at 39.3-41.2°C within 50 minutes. It’s similar to other magnetic wireless chargers, but it has higher power, so it performs well.

And the weight is about 188 g (6.63 oz).

Protocol Test

The ChargerLAB POWER-Z KM003C shows that the USB-C can support UFCS, FCP, SCP, QC2.0, QC5, DCP, PD3.0, and PPS charging protocols.

And it has five fixed PDOs of 5V3A, 9V3A, 12V3A, 15V3A, 20V4.5A and a set of PPS, which is 3.4-21V4.5A.

It can support four sets of UFCS: 5.5-7V4A, 7.0-10V6.6A, 20V7A, and 21V6.6A.

Charging Test

Now, let's take a look at its charging tests.

Compatibility Test

Phones

We use it to charge phones, tablets, game consoles, and laptops during the compatibility test.

Our tester shows that when using it to charge the Huawei Mate60 Pro, the charging power is about 18.4V 4.26A 78.4W.

Use it to charge the nubia Z30 Pro, the charging power is about 18.4V 4.26A 78.4W.

The most phones tested can reach about 9V. Huawei brand phones can reach higher currents and have significantly higher charging power.

Phones compatible with the PPS fast charging protocol, such as nubia Z30 Pro, can reach a power of about 77W. In addition, phones that support the UFCS fast charging protocol will have higher charging power than other models.

Game Consoles

Use it to charge the Lenovo Legion Go, the charging power is about 19.92V 4.31A 85.8W.

As you can see, there is no compatibility issue. The tested devices can reach about 15V and 20V. Basically, it can reach the highest power of the device itself.

We have compiled the test results into a bar chart. The Lenovo Legion Go has the highest charging power of 85.8W. The charging power of the Nintendo Switch is about 15W, while the charging power of the Steam Deck is about 29W.

Tablets

Our tester shows that when using it to charge the 11-inch iPad Pro, the charging power is about 15V 2.17A 32.57W.

As you can see, there is no compatibility issue. The iPads reach a voltage of about 15V, and the other tablets reach about 9V.

We have compiled the test results into a bar chart. The Samsung Tab S8 has the highest charging power of 33.6W. The other tablets can also reach their maximum charging power.

Laptops

Use the Huawei original 140W charger to charge the Huawei MateBook X Pro, the real-time charging power is 19V 6.84A 135.92W.

As you can see, all tested laptops can reach a voltage of about 20V.

We have compiled the test results into a bar chart. The Huawei MateBook X Pro has the highest charging power of nearly 140W. The highest charging power of the rest of the laptops is 89.63W.

Full Charging Test

Next, we'll use it to fully charge the Huawei MateBook X Pro.

The charger and the laptop will be put into a 25°C (77℉) thermotank throughout the test. Here is the charging curve made by the PC software of KM003C.

The voltage is always about 20V. The charging curve can be divided into eight parts. In the first part, the power was about 80W for the first 3 mins. Then, the power increased to 136W and continued until 13 mins. The power then dropped to 58-78W and lasted until 22 mins. Then, the power increased to 136W and continued until 25 mins. The power then dropped to 90W and lasted until 31 mins. Then, the power increased to 136W and continued until 32 mins. Then, the power gradually drops to 120W and 100W in turn. The final part begins at 38 mins, and the power slowly drops to almost zero. It takes 1 hour and 35 mins to be fully charged.

We plot it into another curve to see how fast it can be. It can charge the Huawei MateBook X Pro to 50% in 27 mins and 80% in 44 mins, and it reaches 100% in 1 hour and 35 mins.

Next, we'll use it to fully charge the Huawei Pura70 Pro+.

The voltage is always around 18V. The charging curve can be divided into four parts. In the first part, the peak power stayed at 92W for the first 1 min. Then, the power gradually drops to 68W and 42W in turn. The final part begins at 42 mins, and the power slowly drops to almost zero. It takes 38 mins to fully charge the Huawei Pura70 Pro+.

Standby Power Test

Next, we will test its standby power consumption.

The power consumption at 220V 50Hz is 0.12W, and 0.006W at 110V 60Hz, which is about 1.05 and 0.053KW·h in one year, respectively. So, you do not need to worry about the waste of the electricity.

Conversion Efficiency Test

Then, we are going to the conversion efficiency test. We tested the conversion efficiency at two inputs: 220V 50Hz and 110V 60Hz. Below are the test results.

The conversion efficiency varies from 85.52% to 92.91% at 220V 50Hz, and the conversion efficiency varies from 84.84% to 91.86% at 110V 60Hz. The charger achieves a conversion efficiency of up to 92.91% under the two voltages, which is at the mainstream level for similar devices.

Ripple Test

Power adapters rely on switch-mode power supplies, which means that the output from the transformer's secondary winding is not direct current and must be rectified and filtered by capacitors before being outputted. As a result, ripples can exist in the output signal. To evaluate the quality of the adapter's output, ChargerLAB employs an oscilloscope to test the ripple value of the converter's output and compare it with industry standards. In general, the lower the ripple, the higher the output quality.

Firstly, let's check out its ripple without load. When the output is 5V 0A, the lowest ripple is around 62 mVp-p. When the output is 20V 0A, the highest ripples are around 72 mVp-p.

Then, move to the ripple test when loaded. When the output is 12V 5A, the highest ripple is 76 mVp-p. When the output is 9V 3A, the lowest ripple is 26 mVp-p. Overall, the performance is acceptable.

Temperature Test

Then, we are going to the maximum temperature test. We put the charger into a 25°C (75℉) thermotank throughout the test. And recorded the highest temperature on the front and back after charging at 20V4.5A for an hour.

First, let’s take a look at the temperature under 220V 50Hz after an hour.

After one hour of charging, the maximum temperature on the front is 64.8 ℃ (148.64 ℉).

And the maximum temperature on the back is 61.7 ℃ (143.06 ℉).

Next, let’s take a look at the temperature under 110V 60Hz after an hour.

After one hour of charging, the maximum temperature on the front is 66.1 ℃ (150.98 ℉).

And the maximum temperature on the back is 71 ℃ (159.8 ℉).

Creating a bar chart to represent the data, it is evident that this charger reaches a maximum temperature of 71 ℃ when operating under 110V 60Hz. This temperature complies with the International Electrotechnical Commission (IEC) 62368 standards for electronic and electrical equipment tests, which stipulates that the temperature should not exceed 77 °C, but it is very close.

Summary of ChargerLAB

The Huawei original 140W charger is overall white. It only has one USB-C port and comes with a dual USB-C cable.

The charger is compatible with most charging protocols. Since it supports UFCS 140W protocol and proprietary protocol, it can provide higher charging power for Huawei products. Both standby power consumption and conversion efficiency are at mainstream levels. The results of the ripple test are acceptable. The temperature after charging for an hour is above 70 °C (158 ℉) but as a high-power desktop charger you won't be moving it around often, so temperature isn't a big issue. If you are a Huawei fan or have many Huawei devices, it will be a good choice.

And it has three fixed PDOs of 5V/2.4A, 9V/2.22A, and 12V/1.67A.

Charging Test

Now, let's take a look at its charging test.

Compatibility Test

Integrated Cable

Use the integrated cable to charge the iPhone 16 Pro Max, the power is about 12.13V 1.61A 19.52W.

As you can see, there is no compatibility issue. The phones that can support PD protocol can reach about 9V. Most game consoles, tablets, and laptops can reach about 12V.

We have compiled the test results into a bar chart. The highest charging power is the iPhone 16. The power can be up to 19.91W.

Next, we'll use the Apple 35W charger to fully charge the Tesla Wireless Portable Charger.

The charger and the power bank will be put into a 25°C (77℉) thermotank throughout the test. Here is the charging curve made by the PC software of KM003C.

The voltage is always around 9V. The charging curve can be divided into two parts. In the first part, the peak power stayed at 18W for the first 47 minutes. Then, the power continues to decrease until it is fully charged. It takes 2 hours and 8 mins to be fully charged.

We plot it into another curve to see how fast it can be. It can be charged to 50% in 36 mins and 80% in 1 hour and 2 mins, and it reaches 100% in 2 hours and 8 mins.

Output Efficiency Test

Output efficiency is an important factor in assessing the quality of a power bank. Higher output efficiency indicates a higher conversion rate and less heat generation. We tested this power bank's output efficiency at different power levels because efficiency varies at different output levels.

First, let the power bank output power at 5V2.4A 12W, and the output ends at 16 mins. The actual energy released is about 3.47Wh.

Let the power bank output power at 9V2.2A 19.8W, and the output ends at 5 mins. The actual energy released is about 1.67Wh.

Let the power bank output power at 12V1.67A 20.04W, and the output ends at 4 mins. The actual energy released is about 1.36Wh.

Ripple Test

Firstly, let's check out its ripple without load. When the output is 5V 0A, the lowest ripple is around 15.6 mVp-p. When the output is 12V 0A, the highest ripples are around 19.2 mVp-p.

Then, move to the ripple test when loaded. When the output is 12V 1.67A, the highest ripple is 27.6 mVp-p. When the output is 5V 2.4A, the lowest ripple is 12 mVp-p. Overall, the ripple performance is good.

Temperature Test

Then, we are going to the maximum temperature test. We put the power bank into a 25°C (75℉) thermotank. And recorded the highest temperature on the front and back under the load of 12V1.67A 20W.

With an output of 12V1.67A 20.04W, the maximum temperature on the front is around 32.1℃ (89.78 ℉).

The maximum temperature on the back is 39.6 ℃ (103.28 ℉). At this time, you will feel warm when you touch it. The highest temperature is at the charging port, which is normal.

Summary of ChargerLAB

The Tesla Wireless Portable Charger has a 5000mAh battery capacity and a foldable design that supports wireless charging of two devices at the same time. It can output during input, and the usage scenarios are diversified. It can also be used as a mobile phone holder,

The maximum power of the two wireless charging panels is 10W and 5W, respectively, and the maximum total wireless output is 15W. At the same time, it also supports charging the built-in battery via wireless charging.

It took 2 hours and 8 minutes to be fully charged with the Apple 35W charger. Whether in a no-load or loaded state, the ripple does not exceed 30mVp-p, which is an excellent performance. Under a load of 20W, the maximum temperature is 39.6℃ (103.28 ℉). Overall, the Tesla Wireless Portable Charger not only provides an excellent wireless charging experience, but its USB-C port also provides 20W of input and output power, making it the perfect choice for users with multiple devices.

Then, we are going to the maximum temperature test. We put the charger into a 25°C (75℉) thermotank and under 220V 50Hz throughout the test. And recorded the highest temperature on the front and back after charging at 28V5A for an hour.

After one hour of charging, the maximum temperature on the front is 71.5 ℃ (160.7 ℉).

And the maximum temperature on the back is 70.4 ℃ (158.72 ℉).

Creating a bar chart to represent the data, it is evident that this charger reaches a maximum temperature of 71.5 ℃ when operating under 220V 50Hz voltage setting. This temperature complies with the International Electrotechnical Commission (IEC) 62368 standards for electronic and electrical equipment test, which stipulates that the temperature should not exceed 77 °C, but it is very close.

Summary of ChargerLAB

The MOVESPEED 140W PD3.1 charger has a rounded case and a green matte surface. It is equipped with four USB ports and comes with a dual USB-C cable. It supports automatic power distribution and can charge four devices at the same time.

The charger has no charging compatibility issues and is compatible with most charging protocols. And when multiple ports are used at the same time, it also supports the automatic distribution of charging power. The full charging time of the 16-inch MacBook Pro M1 Max with it is almost the same as that of the original 140W charger. And its size is smaller than the original 140W charger. Both standby power consumption and conversion efficiency are at mainstream levels. However, when at the 20V and 28V voltage values, the ripple is significantly higher than at other values, and the ripple performance is unstable. The temperature after charging for an hour is above 70 °C (158 ℉) but as a high-power desktop charger you won't be moving it around often, so temperature isn't a big issue. It can integrate the fast charging needs of phones, tablets, and laptops, so if you have many devices, it will be a good choice.

Qi2 Wireless Charging: A Simple Review with ChargerLAB POWER-Z KM003C

Joey — Fri, 19 Apr 2024 01:01:00 +0000

Introduction

Following the release of Apple's MagSafe wireless charging technology and its associated MPP protocol, a surge of Qi2-enabled wireless chargers have emerged in the market, promising a similar charging experience to MagSafe chargers without the need for Apple's "MFM" certification.

As a result, there's been a growing interest among users in understanding the real-world performance of these Qi2 wireless chargers. While our ChargerLAB POWER-Z KM003C tester cannot directly measure the real-time power of the wireless transmitter and receiver, it can measure the power input at the cable end and, through reasonable calculations, estimate the power output on the wireless end. Today, we'll be using the Belkin BoostCharge Pro Qi2 Wireless Charging Stand, one of the brands deeply cooperated with Apple, to do the test.

Wireless Charging Test

First, let's take a look at the standby power. Using an Apple 30W charger to power the Belkin BoostCharge Pro Qi2 Wireless Charging Stand, the KM003C measured a power consumption of around 9.03V 0.07A 0.60W, which is within the normal range.

As you can see, even though the gap between the camera module and the charging pad is relatively small, the iPhone 14 Pro Max can still be placed on it properly.

Without upgrading the system to iOS 17, the charger output power is only 9.00V 1.04A 9.38W, and the phone does not support Qi2 15W wireless charging at this time.

After switching to an iPhone 15 with the latest system update, the output power increases to 8.95V 2.16A 19.37W. After accounting for loss, the wireless side reaches approximately 15W.

The situation is similar for the iPhone 15 Plus, with a power output of 8.96V 2.11A 18.88W.

In addition, it can also charge Android phones that support wireless charging, such as this Xiaomi phone. However, since the magnetic function is exclusive to iPhones, you need to fold the charging pad to work properly.

Unfortunately, the power is very low in this case, only 9.03V 0.17A 1.53W, which is almost unusable.

It can also charge this Samsung phone.

The power is much higher, at 9.01V 0.68A 6.13W.

Finally, let's try charging AirPods Pro. The indicator light is orange, indicating that it is charging.

he power is 9.02V 0.29A 2.59W, which is within the normal range.

Summary of ChargerLAB

Through this Qi2 wireless charging test, we found that using chargers that support the Qi2 wireless charging protocol for wireless charging of the iPhone 15 series has a similar status to Apple's MagSafe wireless chargers. Secondly, the iPhone 14 Pro Max (not upgraded to iOS 17) performs the same as ordinary third-party wireless chargers, only supporting 7.5W.

Overall, Qi2 wireless chargers and MagSafe chargers perform very similarly, both offering an excellent user experience. Actual measurements with the KM003C show that the maximum output power on the wireless side is around 15W.

Qi2 MPP Ready | Charging Review of Gopod Group GQ22 Wireless Charging Module

Joey — Tue, 13 Feb 2024 01:29:00 +0000

Introduction

At this year's autumn iPhone 15 series launch event, Apple casually mentioned that the upcoming iPhones would embrace the latest Qi2 wireless charging standard. Later, in official documentation, Apple provided detailed insights into this feature. Moreover, about seven months ago, we reported a high probability of the iPhone 15 supporting 15W Wireless Charging with Qi2.

Fast forward to December 12th, Apple surprised everyone by releasing the official version of iOS 17.2. Besides enhancing the action button and camera experiences, the most significant addition was the formal support for Qi2 chargers on the iPhone 15, 14, and 13 series. This implies that users can now enjoy a 15W wireless fast charging experience similar to MagSafe when using third-party wireless charging products certified with Qi2.

Qi2 Wireless Charging

Let's briefly explore Qi2; it's a new and enhanced wireless charging standard established by the Wireless Power Consortium (WPC) in 2023. Combining Apple's MPP (Magnetic Power Profile) technology, it promises a superior wireless charging user experience and paves the way for future feature developments. ChargerLAB had previously dissected and analyzed several Qi2 certified products, including both flat and vertical designs, all equipped with fast charging modules supporting QC/PD protocols, meeting the specifications required for Qi2 MPP. Now, let's delve into the specifications and performance of the GQ22 wireless charging module.

Product Appearance

The GQ22 wireless charging module boasts an alloy shell, with a front magnetic area crafted from a smooth gray material, offering a refined feel and creating a stark contrast against the surrounding white.

Its back features a semi-open design, sporting a black region at the bottom housing metal-soldered pins, with the positive and negative pole soldering wires extending from this sample.

The length of the wireless charging module is about 59mm (2.32 inches).

The thickness is about 8.4mm (0.33 inches).

And the weight of this module is about 57g (2.01 oz).

Here's how the module looks when held in my hand, slightly larger than the Apple MagSafe charger.

Wireless Charging Test

While charging the iPhone 15 Plus with the GQ22 wireless charging module, the animation mimics that of the Apple MagSafe charger.

Additionally, its idle power consumption is approximately 0.25W.

Charging the iPhone 15 draws an input power of 8.8V 2.11A 18.61W.

Switching to the iPhone 15 Plus, the power decreases to 8.83V 1.82A 16.11W.

Charging the iPhone 15 Pro registers an input power of 8.8V 2.12A 18.68W.

For the iPhone 15 Pro Max, it's quite similar, at 8.8V 2.14A 18.82W.

Finally, let's examine the performance of the iPhone 15 when using the Apple MagSafe charger, which registers at 9.02V 2.1A 18.91W. Thus, there seems to be no significant difference between the two wireless chargers in terms of physical compatibility or charging power.

Full Charging Test

Next, we'll use it to fully charge the iPhone 15. Here is the result recorded by the PC software of KM003C.

The voltage is always around 9V. The charging curve can be divided into multiple parts. First of all, the peak power stayed at 19W from the first 9 mins. Then, the power suddenly drops to 12W, and then raises to 15W. It goes back to 12W in the 16th min. At 44th min, the power gradually drops to 7W, and raises to 13W. Next, it drops to 7.5W. The final part begins at one hour and 32 mins, and the power slowly drops to almost zero. It takes two hours and 10 mins to be fully charged.

We also turn it into another curve. The wireless charging module can charge the iPhone 15 to 50% in 44 mins. And it can reach 80% in one hour and 17 mins, 100% in two hours and 10 mins. The last 20% took nearly half the total time.

Temperature Test

We also put the module into a 25°C (77℉) thermotank throughout the test. After an hour of running, we got the maximum temperature.

At this point, using a thermal imaging camera, we noticed a peak temperature of 43.3°C (110°F) with the power around 12W. It's essential to note that this module is a semi-finished product and lacks a heat dissipation mechanism; hence, this temperature performance is considered normal.

Summary of ChargerLAB

In summary, the integration of the Qi2 protocol into the latest iPhone models marks a significant step in wireless charging technology. With Apple's endorsement of this enhanced standard, the broader market for wireless charging is poised for notable changes.

As more devices adopt the Qi2 certification, users can anticipate a more unified and enhanced wireless charging experience, fostering greater compatibility among various charging products. This move not only elevates the convenience for iPhone users but also signifies a shift toward a more standardized and efficient wireless charging landscape.

The charger has a foldable prongs.

The bundled cable is a dual USB-C type. It's braided from nylon.

The connectors at the cable ends are thicker than others.

The USB-C connector employs a 24-pin design, potentially allowing for more extensive transmission functionalities.

The ChargerLAB POWER-Z KM003C shows that it does not have an E-marker chip.

And its length is also about 2m (6' 56'').

The length of the ROG 65W Gaming Charger Dock is about 49mm (1.93 inches).

The width is about 68mm (2.68 inches).

The thickness is about 33mm (1.3 inches).

And the weight is about 148g (5.22 oz).

It is smaller than Apple’s original 67W charger.

Protocol Test

Our tester shows that the USB-C supports PD3.0, PPS, QC5 protocols.

It also supports five fixed PDOs of 5V3A, 9V3A, 12V3A, 15V/3A, and 20V3.25A, and a set of 5-21V/3A PPS.

And the USB-A only supports the DCP protocol.

We have compiled all of the test results into a bar chart. The charging power of mobile phone devices remains in the range of 10-25W, which is lower than tablets, laptops, and other devices. At the same time, for the ROG Ally, it can provide PD fast charging that is similar to that of some laptops, with a power of about 63W.

USB-A

Our tester shows that when connected to iPhone 15 Pro, the input power is 4.3V 1.22A 5.24W.

Every smartphone we tested triggered 5V1A.

After compiling and creating a new bar chart, we noticed that the charging power of most devices is around 5W.

Full Charging Test

Next, we'll use it to fully charge the iPhone 15 Pro.

The charger will be put into a 25°C (77℉) thermotank throughout the test. Here is the charging curve made by the PC software of KM003C.

The voltage stays at 9V first. The charging curve can be divided into five parts. In the first part, the peak power stayed at 20W from the first 18 mins. Then, the power gradually drops to 16W, 11W and 6.5W in turn. At the same time, the voltage dropped to 5V. The final part begins at one hour and 7 mins, and the power slowly drops to almost zero. It takes one hour and 37 mins to be fully charged.

We plot it into another curve to see how fast it can be. It can charge the iPhone 15 Pro to 50% in 24 mins and 80% in 50 mins, and it also reaches 100% in 1 hour and 37 mins.

Next, we'll use it to fully charge the MacBook Air 15.

The voltage is always around 20V. The charging curve can be divided into four parts. In the first part, the peak power stayed at 63W from the first 41 mins. Then, the power gradually drops to 50W, and 33W in turn. The final part begins at one hour and 17 mins, and the power slowly drops to almost zero. It takes one hour and 57 mins to be fully charged.

We plot it into another curve to see how fast it can be. It can charge the MacBook Air 15 to 50% in 35 mins and 80% in 1 hour and 4 mins, and it also reaches 100% in 1 hour and 57 mins.

Standby Power Test

The power consumption at 220V 50Hz is 0.085W, and 0.067W at 110V 60Hz, which is about 0.79 and 0.59KW·h in one year, respectively. So, you do not need to worry about the waste of the electricity.

Conversion Efficiency Test

The conversion efficiency varies from 77.64% to 89.36% at 220V 50Hz, and the conversion efficiency varies from 78.13% to 89.04% at 110V 60Hz. The charger achieves a conversion efficiency of up to 89.04% under the two voltages, which is at the mainstream level for similar devices.

ISDT Zip 3-in-1 MagSafe Charger USB-C Charging Test - ChargerLAB Compatibility 100

Joey — Sun, 17 Dec 2023 01:17:00 +0000

Introduction

Starting from the iPhone 8, Apple introduced wireless charging for iPhones. However, many people rarely or have never used this seemingly convenient feature, primarily due to difficulties in aligning the phone with the wireless charging pad and inconvenience in using the phone while it lays flat on the table. Apple recognized this issue and upgraded to magnetic wireless charging, known as MagSafe, starting with the iPhone 12 series. Currently, iPhone 12, 13, 14, and 15 series fully support precise alignment magnetic wireless charging, making it more user-friendly.

Not long ago, we introduced a budget-friendly wireless charger, the ISDT Zip 3-in-1 MagSafe Charger, capable of charging iPhone, Apple Watch, and two USB-C devices simultaneously at a price merely one-third of similar products! After that, we did a ChargerLAB Compatibility 100 video for it. Through the video, we believe that everyone has gained some understanding of this charger. Now, we present it in a textual format to provide a more detailed insight into its charging compatibility.

Charging Compatibility Test

Next, ChargerLAB will conduct a comprehensive test on the compatibility of this product's USB-C port, as there is currently no effective method to accurately measure the power of wireless charging. We will evaluating its performance with a selection of more than 100 charging devices. These devices include mobile phones, handheld gaming consoles, wearable devices, tables and laptops, aiming to cover the majority of users' charging scenarios.

Firstly, it is important to know that the maximum output power of its USB-C port is 33W.

Mobile Phones

Summarizing the test data in a table, we can see that except for a few older models like Black Shark 5 Pro, OnePlus 8 Pro, Xiaomi 8, the rest of the phones trigger 9V voltage value, with an overall charging power of around 20W.

Creating a bar chart, the highest charging power is seen in the REDMAGIC 5G, at 26.62W. The overall charging power is distributed in the range of 9-27W; not exceedingly high, yet no incompatibility issues were observed.

Gaming Consoles

Moving on to gaming consoles. Let's start with the popular ROG Ally, which achieves a charging power of up to 31W. We know that Ally's turbo mode operates at 25W in low input power conditions, meaning that using this charger's USB-C port can slowly replenish its power while in turbo mode.

Summarizing the test data in a table, apart from the ROG Ally, the other two consoles, due to their charging performance, only trigger a 15V voltage value.

Presenting the data in a bar chart, the unquestionably highest charging power is in the ROG Ally, at around 31W. Although it can only provide around 23W for the Steam Deck, considering Deck's maximum power draw is around 15W, it's still feasible to charge and play simultaneously.

Wearable Devices

Next in line are wearable devices. Charging the Apple Watch Ultra, the power is around 5W.

Charting the results, all trigger at 5V.

In a bar chart, similar to previous tests, the highest power is from the more expensive Apple Watch Ultra, at 5.2W; the other two watches are both around 2W. All are performing normally.

Tablets

For tablets, it can provide around 24W for the Samsung Tab S8.

Summarizing the test data in a table, all iPads trigger a 15V voltage value, while Android tablets drop to 9V.

In a bar chart, the highest charging power is in the 11-inch iPad Pro (4th Gen), at 27W.
