And it has six fixed PDOs of 5V3A, 9V3A, 12V3A, 15V3A, 20V5A, and 28V5A. It also has a set of AVS, which is 15-28V 140W.

Our tester shows the USB-A port can support QC2.0, FCP, SCP, AFC, DCP, and Apple 2.4A charging protocols.

Charging Test

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

Compatibility Test

USB-C2/C3

Our tester shows that when using the USB-C3 port to charge the MacBook Pro M4 Pro, the power is 27.35V 4.83A 132.11W.

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 132.11W. Phones that support the PPS protocol can also obtain higher charging power, such as the Red Magic 9S Pro+, which can reach 86.45W. The Samsung S23 Ultra supports the AFC protocol, and its power can reach 43.53W. The power of other phones is in the range of 15 to 35W.

USB-A

Use the USB-A to charge the REDMI K80 Pro, the power is 8.73V 1.57A 13.73W.

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 Huawei Mate 70, which is 18.43W. The charging power of OPPO phones is between 16 and 17W. The charging power of other phones can be roughly divided into two power ranges: 14W 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-C2 is 62.37W, and the output power of USB-C3 is 32.11W.

When the three ports output at the same time, the output power of USB-C2 is 57.47W, the output power of USB-C3 is 34.54W, and the output power of USB-A is 13.39W.

Simultaneous Charge and Discharge Test

We will test the output power while charging it.

The input power is 134.94W. The output power of the USB-C2 is 57.48W, the output power of the USB-C3 is 33.89W, and the output power of the USB-A is 13.39W.

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.

The voltage is always around 28 Volts. The power stays at over 130W in the first 47 minutes, with the highest power reaching 135W.Then, the power slowly drops to almost zero. It takes 2 hours and 20 minutes to be fully charged.

It can be charged to 50% in 32 minutes and 80% in 55 minutes, and it reaches 100% in 2 hours and 20 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 8 hours and 14 minutes. The actual energy released is about 113.21Wh. Its efficiency when output at 15W is about 113.12/146=77.48%.

Let the power bank output at 9V3A 27W. 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 4 hours and 12 minutes. The actual energy released is about 114.51Wh. Its efficiency when output at 27W is about 114.51/146=78.43%.

Let the power bank output at 12V3A 36W, the output ends at 3 hours and 22 minutes. The actual energy released is about 116.73Wh. Its efficiency when output at 36W is about 116.73/146=79.95%.

Let the power bank output at 15V3A 45W, and the output ends at 2 hours and 42 minutes. The actual energy released is about 119.35Wh. Its efficiency when output at 45W is about 119.35/146=81.75%.

Let the power bank output at 20V5A 100W, and the output ends at 1 hour and 29 minutes. The actual energy released is about 121.6Wh. Its efficiency when output at 100W is about 121.6/146=82.92%.

Let the power bank output at 28V5A 140W, and the output ends at 1 hour and 3 minutes. The actual energy released is about 116.52Wh. Its efficiency when output at 140W is about 116.52/146=79.81%.

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 19 mVp-p. When the output is 28V 0A, the highest ripple is around 91 mVp-p.

Then, move to the ripple test when loaded. When the output is 28V5A, the highest ripple is 92 mVp-p. When the output is 5V3A, the lowest ripple is 20 mVp-p.

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 30 minutes under a 28V5A 140W load.

After 30 minutes of discharge, the maximum temperature on the front is 39.6℃ (103.28 ℉), and the heat is mainly concentrated in the middle.

The maximum temperature on the back is 36.2℃ (97.16 ℉). At this time, touch the power bank, it feels warm, and the main heating area is the battery cell.

Summary of ChargerLAB

With its top-tier specs like ultra-high capacity and powerful output, the AOHi Starship 40,000mAh 140W Power Bank eliminates the need to carry multiple chargers while on business trips. Featuring PD3.1 protocol compatibility, automotive-grade battery cells, and visualized power output, this power bank stands out as a leader in its class.

With support for multiple protocols, including PD, SCP, AFC, and QC, it offers excellent compatibility with mainstream devices. It also supports simultaneous triple-port output and pass-through charging, ensuring all three ports can operate at full capacity without compromise.

The AOHi 140W charger can fully charge it in 2 hours and 20 minutes. The AOHi Starship achieves a peak conversion efficiency of up to 82.92%. Under both no-load and load conditions, ripple values remain under 100mVp-p, ensuring stable performance. Even under a 140W load, the temperature peaks at around 39°C after 30 minutes, highlighting its excellent thermal management.

In an era where fast-charging technology has become increasingly homogenized, the AOHi Starship 40,000mAh 140W Power Bank sets itself apart by maintaining full power output throughout the entire PD3.1 charging process. Combining the functionality of a desktop charger and a portable power bank into one, it redefines the standard for premium mobile power solutions.
