Product reviews
After introducing the appearance size of the Magic Habitat 30W PD charger, I will take you to see 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.
In terms of protocols, ChargerLAB's POWER-Z KT002 reads the charger's fast charging protocol, and the actual test supports charging protocols such as Apple2.4A, QC2.0, QC3.0, QC4+, PD3.0 and PPS.
In terms of PDO messages, it supports five sets of fixed voltages and 3.3V-11V3A sets of PPS voltage files of 5V3A, 9V3A, 12V2.5A, 15V2A and 20V1.5A, with 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 iPhone 13 Pro Max with approximately 9.25V 2.89A 26.75W.
Charge the iPad Pro at approximately 15.26V 1.9A 29.03W.
Charge the MacBook Pro 16 at approximately 20.31V 1.43A 29.12W.
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 can clearly see the changes in parameters during charging, and the model used this time is the iPhone 13 Pro Max, to see the data changes throughout the charging process.
52 minutes before charging, the charging voltage is maintained at about 9V, and the maximum power is around 27W. The voltage will then reach 5V and enter trickle charging mode, which takes 1 hour and 42 minutes.
The charging data is sorted into a graph, half an hour before charging, the charge is about 54%, the one-hour charge is 86%, and the whole process takes 1 hour and 42 minutes.
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 0.04W, converted to a year of loss of power is about 0.35KW · h, if the market price of electricity is 0.6 yuan / KW · h, the charger's annual electricity cost is about 0.21 yuan.
110V 60Hz no-load power consumption of 0.017W, converted down, a year loss of electrical energy is about 0.148KW·h, if the market price is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.08 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 power from the socket is often larger, 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 86.35% to 91.16%.
At 110V 60Hz, the conversion efficiency of the charger varies from 88.37% to 90.58%.
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 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, the highest 164mVp-p charger is at 5V3A output; the lowest 24mVp-p charger is at 20V0A no-load.
At 110V 60Hz, the maximum is 156mVp-p, and the charger is at 5V3A output; the minimum 24mVp-p charger is at 20V0A no load.
Ripple test summary
The national standard in the charger ripple requirement is not higher than 200mVp-p, Moqi 30W PD charger in 110V 60Hz, 220V 50Hz input voltage, all output power ripple peak-to-peak are lower than 200mVp-p this standard, good performance.
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. The charger is continuously output at 30W power for one hour, the surface temperature of the charger is collected, and the charger is placed 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 front of the charger is 58.2 °C.
The maximum temperature on the back of the charger is 63.3°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 61.8 °C.
The maximum temperature on the back of the charger is 61.2°C.
Full load stability test
After long-term use, will the charger be reduced due to overheating? The charging head network also tested the Magic Habitat 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.
