The whole charging process is drawn into a curve, and it can be seen that half an hour of charging is 55%, 1 hour of charging is 80%, and it takes 2 hours and 2 minutes to fully charge.
Because the Anker Nano Pro 40W charger is equipped with a dual USB-C interface that supports 20W+20W output when the dual ports are output at the same time, it also added the use of two USB-C interfaces to charge the iPhone 12 and iPhone 12 Pro at the same time to see the whole test.
This is the data change situation of using one of the USB-C for the entire charging of the iPhone 12, the voltage rises from 5V to 9V into PD fast charging at 2 minutes, drops from 9V to 5V at 58 minutes into trickle charging, the test ends at 2 hours and 1 minute, and the maximum power is 9.17V 1.87A 17.24W.
The data of the iPhone 12 charging process will be plotted, and it can be seen that it takes 52% of the half hour to charge, 81% to charge in 1 hour, and 2 hours and 1 minute to fully charge.
This is the data change situation of charging the iPhone 12 Pro at the same time using another USB-C, the voltage rises from 5V to 9V into PD fast charging at 2 minutes, drops from 9V to 5V at 57 minutes into trickle charging, and the test ends at 1 hour and 59 minutes, with a maximum power of 9.21V 2A 18.46W.
Drawing the whole charging process into a curve, it can be seen that half an hour of charging 53%, 1 hour of charging 83%, fully charging takes 1 hour and 59 minutes.
A summary of the entire charging process
The Anker Nano Pro 40W charger is very friendly to iPhone users, feeding the iPhone 13 Pro Max with 40W of fast charging power, and can meet the fast charging needs of two iPhones. Whether it is a single-port output or a dual-port simultaneous output, it can meet the needs of charging more than 50% of the iPhone for half an hour.
Standby power consumption test
If the charger is often plugged into the socket and not used, it will consume power, but it is very small. Many readers want to know whether the charger is wasted if it is always plugged into the socket, and the standby power consumption test session is to answer this question.
After the power meter test, the charger in 220V 50Hz no-load power consumption of 0.091W, converted to a year of loss of electrical energy is about 0.79KW· h, if the market price of electricity is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.47 yuan.
The no-load power consumption at 110V 60Hz is 0.074W, which translates to a year's loss of electrical energy of about 0.64KW·h, and if the market price is 0.6 yuan /KW·h, the charger's annual electricity cost is about 0.38 yuan.
Conversion efficiency testing
A charger is essentially a conversion device that is lost during the process and dissipated in the form of heat. We usually look at the charger above the parameter output 100W or 65W is the maximum output power that the charger can provide for the device, but the charger draws more power from the socket, the following is the charger in the case of 220V 50Hz and 110V 60Hz AC input respectively carried out conversion efficiency test, the test results are as follows.
At 220V 50Hz, the output power of the charger in each voltage gear is fully tested: the input power of the AC terminal of the power strip and the output power of the USB terminal are measured in four gears, and the conversion efficiency of the available charger varies from 82.23% to 88.94%.
At 110V 60Hz, the conversion efficiency of the charger varies from 82.93% to 88.23%.
Ripple test
Due to the switching power supply in the charger, the secondary output of the transformer is not direct current, and it needs to be rectified and capacitor filtered, that is, there will be ripple in the charger output. The charging head network uses an oscilloscope to test the ripple value of the charger output, compare with the national standard, and detect the output quality of the charger. The lower the ripple, the higher the output quality of the charger.
This is the use of the charger at 220V 50Hz AC input ripple test, ripple test is divided into no load (Y axis current in the histogram is 0A) and heavy load (the Y axis current in the histogram is not 0A) two, the maximum is 166mVp-p, the charger is in the 15V0A no-load state; the minimum is 12mVp-p, the charger is in the 5V0A no-load state.
At 110V 60Hz, the maximum is 146mVp-p, the charger is in the 15V0A no-load state, and the minimum is 12mVp-p, and the charger is in the 5V0A no-load state.
Temperature testing
As mentioned earlier, the charger will involve the problem of efficiency conversion, and the vast majority of the lost power is dissipated by heat, so the heat of the charger working for a long time is also an important part of the test. Let the charger output at 40W power for one hour continuously, collect the surface temperature of the charger, and place the charger in a 25 °C incubator throughout the experiment.
First, let's take a look at the temperature performance of the charger in the mains environment of 220V50Hz.
The maximum temperature of the charger surface after 1 hour is 65.4 °C when shooting with a thermal imager.
The maximum temperature on the other two sides is 67.1 °C.
Look at the temperature performance of the charger in the mains environment of 110V60Hz.
The maximum temperature of the charger surface after 1 hour is 60.8 °C when photographed using a thermal imager.
The maximum temperature on the other two sides is 70 °C.
1 hour full load stability test
After long-term use, will the charger be reduced due to overheating? The charging head network also tested the Xiaomi Mi 67W Gallium Nitride charger.
The charger gear is adjusted to 20V2A, and the output is continuously output at 40W for one hour, and the voltage and current are horizontal and straight during the test, without obvious fluctuations, and the use of full load for a long time is also quite stable.
