There are no compatibility issues. The voltage of the tested devices reaches 9V or 5V.

Summarize all test results into a bar graph. The highest charging power is the iQOO 13, which is 17W. The second is the Huawei Mate70 Pro+ supports SCP charging protocol, with a power of 17.01W. Next are OPPO models, all around 16W, and the rest are in the range of 5 to 15W.

Multi-port Output Test

When the two USB-C ports are outputting at the same time, the output power of USB-C1 is 61.19W, and the output power of USB-C2 is 57.44W.

When the three ports output at the same time, the output power of USB-C1 is 63.44W, the output power of USB-C2 is 39.18W, and the output power of USB-A is 13.62W.

Digital Hybrid Technology

Digital hybrid technology can transform the original adapter into a multi-port charger, enabling up to two laptops to be powered simultaneously, and power other devices while charging the power bank. A single port can be turned into a multi-port charger in seconds, making storage convenient.

When the power bank is inputting, the input power is 94.48W, and the output power of USB-C1 is 86.16W.

When outputting to two devices, the input power is 97.05W, the USB-C2 output power is 97.07W, and the USB-A output power is 13.61W.

Full Charging Test

Next, we'll use an original 140W charger to fully charge it. They 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 20V. The power is around 93W for the first 26 minutes. Then, the power drops to 44W. It briefly rises to 84W at 47 minutes. After that, the power slowly drops to almost zero. It takes 1 hour and 24 minutes to be fully charged.

It can be charged to 50% in 24 minutes and 80% in 49 minutes, and it reaches 100% in 1 hour and 24 minutes.

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 at 5V3A 15W, and the output ends at 3 hours and 53 minutes. The actual energy released is about 55.52Wh. Its efficiency when output at 15W is about 55.52/73=76.06%.

Let the power bank output at 9V3A 27W, and the output ends at 2 hours and 13 minutes. The actual energy released is about 57.42Wh. Its efficiency when output at 27W is about 57.42/73=78.66%.

Let the power bank output at 12V3A 36W, and the output ends at 1 hour and 41 minutes. The actual energy released is about 57.84Wh. Its efficiency when output at 36W is about 57.84/73=79.23%.

Let the power bank output at 15V3A 45W, and the output ends at 1 hour and 21 minutes. The actual energy released is about 59.22Wh. Its efficiency when output at 45W is about 59.22/73=81.12%.

Last, let the power bank output at 20V7A 140W. The temperature protection is triggered in 8 minutes and the discharge ends. The actual energy released is about 18.22Wh.

Since the test instrument used is in constant current and constant voltage mode, the discharge is interrupted after the temperature protection is triggered, and the input terminal on a laptop or other high-power equipment can adapt, so this situation will not occur.

Ripple Test

Firstly, let's check out its ripple without load. When the output is 5V 0A, the lowest ripple is around 25.6 mVp-p. When the output is 20V 0A, the highest ripple is around 69.6 mVp-p.

Then, move to the ripple test when loaded. When the output is 20V7A, the highest ripple is 68 mVp-p. When the output is 5V3A, the lowest ripple is 21.6 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 record the maximum temperature on the front and back after 8 minutes under a 20V7A 140W load.

After 8 minutes of discharge, the maximum temperature on the front is 52.8℃ (127.04 ℉), and the heat is mainly concentrated in the middle.

The maximum temperature on the back is 40.9℃ (105.62 ℉). The temperature on the back is much lower than that on the front.

USB-C1/C2

Our tester shows that when charging the MacBook Pro M4 Pro through the USB-C1 port with the original MagSafe 3 cable, the power is 27.77V 4.81A 133.47W.

As you can see, there is no compatibility issue. Most phones can reach 9V voltage, and models that support the PPS protocol can reach 17V voltage. Tablets, game consoles, and laptops can mostly reach 15V or 20V voltage. MacBook Pro 16 M4 Pro supports PD3.1 protocol and the voltage can reach 28V.

We have compiled all of the test results into a bar chart. The MacBook Pro 16 M4 Pro has the highest power, which can reach 133.47W. Models that support the PPS protocol can also obtain higher charging power, such as Red Magic 9S Pro+, vivo X200 Pro, etc., while the rest are in the range of 8 to 35W.

USB-A

Use the USB-A to charge the REDMI K80 Pro, the power is 8.58V 1.57A 13.5W.

There are no compatibility issues. The voltage of the tested devices reaches 9V or 5V.

Summarize all test results into a bar graph. The highest charging power is Samsung S23 Ultra, which is 14.1W. The charging power of other phones can be roughly divided into two power ranges: 13W and 10W, and the overall charging power is relatively stable.

Multi-port Output Test

When the two USB-C ports are outputting at the same time, the output power of USB-C1 is 118.68W and the output power of USB-C2 is 94.17W, which is in line with the official output allocation of 140W+100W.

When the three ports output at the same time, the output power of USB-C1 is 93.55W, the output power of USB-C2 is 85.93W, and the output power of USB-A is 13.46W.

Simultaneous Charge and Discharge Test

We will test the output power while charging it.

The input power is 135.41W. The output power of the USB-C1 is 86.81W, and the output power of the USB-A is 13.5W.

Full Charging Test

Next, we'll use an AOHi 140W charger to fully charge it. They will be put into a 25°C (77℉) thermotank throughout the test. Here is the charging curve made by the PC software of KM003C.

At first, the voltage is around 28V. The charging curve can be divided into six parts. The power is around 135W for the first 5 minutes. After that, the voltage drops to 20V. Then, the power gradually drops to 97W, 64W, and 44W in turn. It briefly rises to 64W before dropping back to 44W. The final part begins at 1 hour and 44 minutes, and the power drops to almost zero. It takes 2 hours and 16 minutes to be fully charged.

It can be charged to 50% in 48 minutes and 80% in 1 hour and 31 minutes, and it reaches 100% in 2 hours and 16 minutes.

Output Efficiency Test

First, let the power bank output at 5V3A 15W, and the output ends at 6 hours and 7 minutes. The actual energy released is about 79.39Wh. Its efficiency when output at 15W is about 79.39/99.36=79.9%.

Let the power bank output at 9V3A 27W, and the output ends at 3 hours and 24 minutes. The actual energy released is about 90.25Wh. Its efficiency when output at 27W is about 90.25/99.36=90.83%.

Let the power bank output at 12V3A 36W. Since AOHi has designed this power bank to limit the power when the power is below 10% to prevent over-discharge, the remaining 10% of power is uniformly discharged at 45W and counted into the total. The output ends at 2 hours and 30 minutes. The actual energy released is about 90.47Wh. Its efficiency when output at 36W is about 90.47/99.36=91.05%.

Let the power bank output at 15V3A 45W, and the output ends at 1 hour and 58 minutes. The actual energy released is about 85.43Wh. Its efficiency when output at 45W is about 85.43/99.36=85.98%.

Let the power bank output at 20V5A 100W, and the temperature protection is triggered and ends at 23 minutes. The actual energy released is about 35.52Wh.

Last, let the power bank output at 28V5A 140W, and the temperature protection is triggered and ends at 10 minutes. The actual energy released is about 24.06Wh.

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 16 mVp-p. When the output is 15V 0A, the highest ripple is around 25 mVp-p.

Then, move to the ripple test when loaded. When the output is 28V5A, the highest ripple is 33 mVp-p. When the output is 5V3A, the lowest ripple is 26 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 record the maximum temperature on the front and back after 10 minutes under 28V5A 140W load.

After 10 minutes of discharge, the maximum temperature on the front is 51.8℃ (125.24 ℉), and the heat is mainly concentrated in the middle.

The maximum temperature on the back is 34.7℃ (94.46 ℉). The temperature on the back is much lower than that on the front.

Summary of ChargerLAB

The AOHi Starship 240W Power Bank combines a compact form factor with high output power. By integrating ultra-large capacity, blazing-fast charging, and intelligent interaction, it addresses the core needs of multi-device users. It features two USB-C ports and one USB-A port, with both USB-C ports supporting fast charging protocols such as UFCS, PD, SFCP, QC, and 5A PPS—covering the charging requirements of most modern devices. It also supports triple-port simultaneous output as well as charging while discharging.

When charged using the AOHi 140W charger, it takes 2 hours and 16 minutes to reach full capacity. Its conversion efficiency reaches 80% across most output levels and can even go up to 90%. Ripple remains below 35mVp-p in both no-load and full-load conditions. After discharging at 28V 5A 140W for 10 minutes, the front of the device reaches a maximum temperature of 51.8°C (125.24°F), while the back stays at a relatively cool 34.7°C (94.46°F).

All in all, the AOHi Starship 240W Power Bank seamlessly blends futuristic design, outstanding performance, and top-tier safety. For users who demand both efficiency and quality, this may very well represent the pinnacle of power bank performance.

Introduction

Apple’s latest iPad Air M3 comes with a 28.93Wh battery, offering up to 10 hours of video streaming on a single charge. It ships with a 20W charger, but the packaging indicates support for up to 45W input (15V 3A).

So, what is the actual maximum charging power of the iPad Air M3? How well does it work with Apple’s original chargers, third-party adapters, and power banks? Let’s find out.

Charging Compatibility Test

Original Chargers

First, we tested the included 20W charger. The measured charging power at the iPad's input end was 8.65V 2.13A, or 18.45W.

Interestingly, when switching to a 70W Apple charger, the power only increased to 14.64V 2.01A, or 29.50W, which is far below the 45W indicated on the packaging.

To provide a clearer comparison, we compiled a summary of charging performance across multiple Apple original chargers. As expected, Apple’s chargers generally offer excellent compatibility.

Visualizing the data in a bar chart, we observed that all Apple chargers, except for the 87W model, were able to deliver either their own maximum power output or the iPad’s actually charging limit. The highest recorded power was 29.81W.

Third-party Chargers

If you ever forget your charger, you might have to rely on a third-party power adapter. So, how well does the iPad Air M3 work with non-Apple chargers when using the original USB-C cable?

We tested a Lenovo ThinkPlus 65W charger, which delivered 14.75V 2.12A, or 31.32W—even higher than Apple’s own chargers.

fter compiling data from multiple third-party chargers, we found that most chargers successfully triggered the 15V power profile, while a few operated at 9V or 12V.

Plotting this data in a bar chart, we saw that nearly all third-party chargers reached either their own maximum output or the iPad’s peak supported charging speed. The overall compatibility was excellent, and surprisingly, some third-party chargers even outperformed Apple’s original ones, with a maximum recorded power of 31.32W.

Power Banks

Finally, we tested power banks. The ZMI No.20 power bank charged the iPad at 14.59V 2.04A, or 29.81W.

The Xiaomi 20,000mAh 50W power bank delivered 14.62V 2.01A, or 29.31W.

Summarizing the results, we found that all tested power banks charged the iPad Air M3 at either 9V or 15V, with currents ranging from 1A to 2A.

A graphical comparison revealed a pattern similar to third-party chargers: most power banks achieved their highest possible PD fast-charging power, demonstrating excellent compatibility.

Summary of ChargerLAB

iPad Air M3 comes with a 20W charger, and the packaging states that it supports up to 45W input. However, actual testing shows that the maximum charging power is only around 31W.

In terms of charging compatibility, Apple’s original chargers continue to perform excellently, with most of them reaching either their own maximum power output or the iPad’s supported limit of around 30W. As for third-party chargers and power banks, the iPad also demonstrates excellent compatibility, achieving the highest PD fast-charging power supported by either the charger, power bank, or the iPad itself.
