Review of Aigo AU1020 20W Charger (perfect for iphone)
The orange and white box is made of environmentally friendly paper. The front is printed with the appearance of the charger and the 20W, and the aigo logo is in the upper left corner.
The specifications are printed on the back. The model is AU1020 and the USB total power output is up to 20W.
The features of 20W fast charging, USB-C port and wide voltage output are printed on the side.
Inside the package, there are the 20W charger and instructions.
The white glossy charger shell adopts the PC with V0 flame-retardant material.
The prongs are not foldable.
The specifications show:
Output: 5V3A, 9V2.23A, 12V1.67A, 3.3-5.9V3A, 3.3-11V2.2A
Manufacturer: Shenzhen Aoda Power Technology Co., Ltd.
The black single USB-C port is on the bottom.
The ChargerLAB POWER-Z KM002C shows that it supports FCP, SCP, AFC, QC3.0, QC4/4+, PD3.0 and PPS fast charging protocols.
ChargerLAB will use tens of devices for compatibility testing to present readers with the most accurate data.
It is 8.89V 2.16A 19.24W, the maximum power output when the charger is charging the iPhone 13 Pro Max.
It is 8.9V 1.94A 17.28W when charging the iPhone 13 Pro.
Here comes the charging compatibility test of Aigo 20W. It supports fast charging for almost all devices.
ChargerLAB's histogram shows the charging power of each product directly.
Full Charging Test
This is the charging curve of fully charging iPhone 13 with Aigo AU1020 20W charger. The input was at about 20W in the first 18 minutes, and by 32 minutes, it gradually dropped to about 16W; by 43 minutes, it gradually decreased to 11W and ended at 2 hours and 4 minute. The maximum power is 8.89V 2.21A 19.61W.
Standby Power Test
Nowadays, most users won't unplug the charger from the outlet after charging. So it's necessary to figure out if there is any power comsumption in this case and how much it is. Let's have a standby power test.
The power meter shows that the standby power consumption of the charger at 220V 50Hz is 0.065W, which equals about 0.56KW-h in a year. At 110V 60Hz, it is 0.038W, equaling about 0.33KW-h one year.
The lower the value of the standby power consumption, the better. The Aigo 20W charger performs well at both 220V and 110V.
Conversion Efficiency Test
The charger is essentially a conversion device. So energy will be lost in the process of converting. Here comes the conversion efficiency test of Aigo 20W.
The conversion efficiency shows the quality of the charger. The higher the percentage, the better.
The conversion efficiency of the Aigo 20W varies from 85.04% to 89.54% at 220V 50Hz and 85.52% to 88.47% at 110V 60Hz. The data shows that the charger's efficiency is mostly around 88%, which is a high level for the 20W chargers.
Most chargers adopt switching power supply currently. And there will be ripples in the output current. The lower ripple means better quality.
The ripple test is divided into no-load (when the current is 0A) and loaded (when the current is non-0A).
When no-load, at 220V 50Hz, when the output is 5V0A, the highest ripple is 46mVp-p. And when the output is 12V0A, the lowest ripple is 32mVp-p.
At 110V 60Hz, when the output is 5V0A, the highest ripple is 42mVp-p. And when the output is 12V0A, the lowest ripple is 22mVp-p.
When loaded, at 220V 50Hz, when the output is 9V2.23A, the highest ripple is 74mVp-p. And when the output is 5V2A, the lowest ripple is 54mVp-p.
At 110V 60Hz, when the output is 9V2.23A, the highest ripple is 48mVp-p. And when the output is 5V2A, the lowest ripple is 30mVp-p.
As we mentioned, in the process of converting AC to DC, energy will be converted into heat. We'll put it into a 25°C thermotank throughout the test and let it run for an hour with the power of 12V1.67A 20W.
An hour later, the maximum temperature on the A and B sides was 53.3°C under 220V 50Hz.
And the maximum temperature on the C and D sides was 55.2°C.
An hour later, the maximum temperature on the A and B sides was 56.2°C under 110V 60Hz.
And the maximum temperature on the C and D sides was 58.5°C.
The summarized data shows that the overall temperature is about 55 ℃.
Here is the histogram. The highest temperature is only 56.2 ℃, and the lowest is only 53.3 ℃, which is very well.
Summary of ChargerLAB
The new Aigo AU1020 20W charger is compact and convenient to carry. With a maximum of 12V and 20W, it perfectly matches the iPhone and other phones. With the original data cable, Aigo 20W charger supports PD fast charging for iPhone 8-12.
It supports FCP, SCP, AFC, QC3.0, QC4/4+, PD3.0 and PPS fast charging protocols, three fixed PDOs of 5V3A / 9V2.23A / 12V1.67A and two PPS of 3.3-5.9V3A and 3.3-11V2.2A. It also performs well in the standby power test, ripple test and conversion efficiency test.
