Aggregate all charging compatibility test data for easy viewing.
The histogram section can clearly see the level of charging power of each device.
Full test of charging
The Black Shark 30W charger can just meet the power requirements of the iPhone 13 Pro Max, so the charging test chooses to charge the iPhone 13 Pro Max, and the following is the measured data.
This is the data change of the entire process of charging the iPhone 13 Pro Max using the Black Shark 30W charger, the whole process is divided into three stages, and finally ends at 1 hour and 50 minutes of charging, with a maximum power of 9.12V 2.92A 26.73W.
Drawing the whole charging data into a graph, and adding the data from the Apple 30W charger charging the iPhone 13 Pro Max, you can see that the two curves almost coincide.
At the half-hour time point, the Black Shark 30W charged faster and could be charged with 51% of the power; the two chargers charged the same amount of power at the 1-hour time point; the difference between the two was only 3 minutes when it was fully charged. Charging the iPhone 13 Pro Max with the Black Shark 30W charger can get the same fast charging effect as the Apple 30W charger.
Standby power consumption test
Nowadays, it is the norm for users to use the charger to charge their devices and no longer unplug them from the outlet. 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 0.043W, converted to a year's loss of electrical energy is about 0.37KW·h, if the market price of electricity is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.222 yuan.
The no-load power consumption at 110V 60Hz is 0.041W, which translates to a year's loss of electrical energy of about 0.35KW·h, and if the market price is 0.6 yuan /KW·h, the charger's annual electricity cost is about 0.21 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 charger is calculated from 86.59% to 90.44%.
At 110V 60Hz, the conversion efficiency of the charger varies from 85.79% to 89.37%.
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.
The ripple test is divided into two types: no load (0A current on the Y axis in the histogram) and heavy load (the current on the Y axis in the histogram is not 0A). In the no-load part, the charger has the highest ripple at 38mVp-p when it is in the 5V0A no-load state at 220V 50Hz AC input, and the lowest ripple at 24mVp-p when it is in the 20V0A no-load state.
The charger has the highest ripple of 32mVp-p when it is in the 5V0A no-load state at 110V 60Hz AC input and 26mVp-p when it is in the 15V0A and 20V0A no-load states.
In the heavy-duty section, the charger has the highest ripple at 94mVp-p when it is in the 15V2A output state at 220V 50Hz AC input, and the lowest ripple at 66mVp-p when it is in the 20V1.5A output state.
The charger has the highest ripple of 86mVp-p at 12V2.5A and 5V3A outputs at 110V 60Hz AND 60MVp-p at 20V1.5A output.
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 20V1.5A 30W 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.
After 1 hour, the maximum temperature of the two side surfaces of the charger was 69.9 °C when photographed using a thermal imager.
The maximum temperature on the other two sides is 61.7 °C.
Look at the temperature performance of the charger in the mains environment of 110V 60Hz.
After 1 hour, the maximum temperature of the surfaces on both sides of the charger is 64.1 °C when photographed using a thermal imager.
The maximum temperature on the other two sides is 64.4 °C.
Summarize the temperature data for easy viewing.
From the histogram, it is clear that the maximum temperature and the minimum temperature can be clearly seen.
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 Black Shark 30W PD charger.
The charger gear is adjusted to 20V1.5A, and the output is continuously output at 30W power 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.
Charging head net summary
After reading it, do you think that the temperament of this charger is enough for spaceflight? White brushed shell, excellent texture, stand-up 30W PD output, iPad, iPhone can be used. Performance this piece is really pinched, whether it is a rich fast charging protocol, support Apple 2.4A, QC2.0, QC3.0, QC4+, AFC, FCP, SCP, PD3.0 and PPS and other charging protocols; or a small size, 0.83W/cm power density, in all aspects it is a balanced choice in 30W chargers.
