After turning on the power, shake the 20V voltage, and the power is stable at about 63W in the first 1 hour and 13 minutes; Then the power drops to about 44W and continues to charge until the 1st hour and 30 minutes; Then the power continues to drop, and the second hour enters a trickle charge until the computer is fully charged, and the whole charging takes about 2 hours and 27 minutes
Drawing a line chart, it can be seen that the mobile speed 65W charger USB-C takes 49 minutes to charge the MacBook Pro 16 M1 Max to 50%, 1 hour and 19 minutes to 80%, and about 2 hours and 27 minutes to 100%.
No-load power consumption test
Whether the charger will waste power when not used in the socket, and how much power will be lost, this is the question in the minds of many readers, and the standby power consumption link is to answer this question. Plug the charger into the socket of the Becky power meter and read the data on the power meter, the test results are as below.
After the power meter test, the no-load power consumption of the charger at 220V 50Hz voltage is 0.088W.
Let's look at the no-load power consumption at 110V 60Hz voltage, the power consumption read by the power meter is 0.044W, which translates to a year's loss of about 0.385W•h

Overall, the GaN 65W moving speed charger under the two types of voltage is the mainstream level among similar chargers.
Ripple test
Since the switching power supply is used in the charger, the secondary output of the transformer is not direct current, and the output needs to be rectified and capacitive filtered, that is, there will be a ripple in the charger output; The charging head network uses an oscilloscope to test the ripple value of the charger output, compare it with the industry standard, and detect the output quality of the charger. The lower the ripple, the higher the output quality of the charger.

Temperature test
The charger is a conversion device, and there will be losses during the charging process, which will be dissipated in the form of heat, so the charger will heat up. The C port of the GaN 65W output and the charger is placed in a 25°C incubator to collect the temperature of the charger surface after one hour of 20V3.25A load.
First, look at how the charger temperature behaves at a 220V 50Hz voltage output
