preface
Beth is a brand that everyone is very familiar with, recently Beth in Shenzhen jointly recycled treasure, jointly opened a charger to replace the old with a new activity, you said that the change is changed, but also to change the gallium nitride is also too polite, right? The charging head network has also been replaced by this newly listed 30W Gallium nitride charger, in the end how the performance is, how to charge compatibility for different models, which is for everyone to be measured on the machine.

Product reviews
After introducing the appearance size of the Beth 30W Gallium Nitride 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.
Charging protocol testing
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 at approximately 8.9V 2.93A 26.14W.
Charge the Samsung S20 Ultra with approximately 9.13V 2.84A 26.01W.
Charge the iPad Pro at approximately 14.97V 1.9A 28.43W.
Charge the MacBook Pro 16 at approximately 20.01V 1.42A 28.41W.
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.
53 minutes before charging, the charging voltage is maintained at about 9V, the maximum power is about 27W, and then the voltage drops to 5V, entering the trickle charging mode, the whole process takes 2 hours and 1 minute.
The charging data is plotted as a graph, half an hour before charging, the recharge is about 46%, and the charge is about 78% in 1 hour, and the whole process takes 2 hours and 1 minute.
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 0.042W, converted to a year of loss of electrical energy is about 0.367KW· h, if the market price of electricity is 0.6 yuan / KW ·h, the charger's annual electricity cost is about 0.22 yuan.
110V 60Hz no-load power consumption of 0.041W, converted down, a year of loss of electrical energy is about 0.359KW·h, 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 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 plug board and the output power of the USB terminal, and the conversion efficiency of the available charger varies from 87.29% to 92% by calculation.
At 110V 60Hz, the conversion efficiency of the charger varies from 87.04% to 90.91%.
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 88mVp-p charger is at 20V1.5A output; the minimum 34mVp-p charger is at 20V0A output.
At 110V 60Hz, the maximum is 106mVp-p, and the charger is at 9V3A output; the minimum 32mVp-p charger is at 20V0A no load.
Ripple test summary
The national standard in the charger ripple requirement is not higher than 200mVp-p, Beth 30W Gallium Nitride 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 charger front is 69°C.
The maximum temperature on the back of the charger is 63°C.
Look at the temperature performance of the charger in the mains environment of 110V60Hz.
After one hour, the maximum temperature on the front of the charger is about 70.2 °C.
The maximum temperature on the back of the charger is about 63.9°C.
Full load stability test
After long-term use, will the charger be reduced due to overheating? The charging head network also tested the Beth 30W Gallium Nitride 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
Beth 30W Gallium Nitride Charger from the shape, continuing its own Gallium Nitride charger design language, corner LED indicators, so that this product to the hand has an indescribable sense of familiarity. In such a small size, Besse still tucked into the folding pin, so that the power density to 0.89W/cm, portability is definitely the best in its class.
In terms of performance, the single USB-C interface configuration supports Apple2.4A, QC2.0, QC3.0, QC4+, PD3.0 and PPS charging protocols, five sets of fixed voltages and a set of PPS variable voltages, and complete gear configurations. In the actual test, the compatibility and stability are good, and this wave of old-for-new can be said to be blood earned.
