Product reviews
After introducing the appearance size of The 30W Gallium Nitride charger of Taipower, I will take a look at the specific experience of this charger. The charging head network will take everyone to understand this charger from the aspects of protocol test, compatibility test, charging test, standby power consumption test, etc.
Protocol testing
Standby power consumption test
In terms of PDO messages, it supports five sets of fixed voltages of 5V3A, 9V3A, 12V2.5A, 15V2A and 20V1.5A and 3.3V-11V3A, 3.3V-16V2A, which has better device compatibility.
Charging compatibility testing
The compatibility test link can clearly know the charging situation of the charger for each device, and the charging head network will use dozens of devices with the charger for testing, presenting the reader with real test data.
Charge the Huawei Mate 40 Pro with approximately 8.61V 2.37A 20.46W.
Charge the iPad Pro at approximately 15.15V 1.9A 28.93W.
Organize the data into tables and the charger compatibility is quite good.
The charging power is sorted from high to low, and the histogram is made to make a histogram to intuitively compare the difference in charging power between different devices.
Full test of charging
The whole test of charging was selected to charge the iPhone 13 Pro Max, and the following is the measured data.
This is the use of Taipower 30W Gallium Nitride charger for the iPhone 13 Pro Max charging the whole test curve, the whole process can be roughly divided into three stages, 2 minutes 3s, the voltage from 5V to 9V into PD fast charge; 49 minutes 52s voltage from 9V to 5V input into the trickle charging state, in 2 hours and 7 minutes charging ends.
The whole charging process is drawn into a curve, and the 30W Gallium Nitride charger of The Taiwan power supply charges 53% for the iPhone 13 Pro Max in half an hour, 80% in 1 hour, and takes 2 hours and 7 minutes to fully charge.
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 0.044W, converted to a year of loss of power energy is about 0.38KW · h, if the market price of electricity is 0.6 yuan / KW · h, the charger's annual electricity cost is about 0.228 yuan.
The no-load power consumption at 110V 60Hz is 0.036W, which translates to a year's loss of electrical energy of about 0.31KW·h, and if the market price is 0.6 yuan/KW·h, the charger's annual electricity cost is about 0.18 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: five gears are measured to measure the input power of the AC terminal of the power strip and the output power of the USB terminal, and the conversion efficiency of the available charger varies from 87.38% to 91.06%.
At 110V 60Hz, the conversion efficiency of the charger varies from 87.14% to 90.12%.
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 (Y axis current in the histogram is non-0A) two, up to 218mVp-p, the charger is at 9V0A no-load; the minimum is 52mVp-p, the charger is at 20V1.5A output.
At 110V 60Hz, the maximum is 112mVp-p, the charger is at 5V3A output, and the minimum is 28mVp-p, and the charger is at 20V0A no load.
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 30W power for one hour, 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.
After one hour, the maximum temperature of the charger front is 61.5 °C.
The maximum temperature on the back of the charger is 59.7°C.
Look at the temperature performance of the charger in the mains environment of 110V60Hz.
After one hour, the maximum temperature of the charger front is 62.2 °C.
The maximum temperature on the back of the charger is 59°C.
Charging head net summary
