Application case: How to test the power of a PD charger at 100W
Required materials:
1. A charger that supports PD 100W power (self owned)
2. We need a PD trigger (capable of triggering PD 5V 9V 12V 20V voltage) (to be purchased separately)
3. An electronic load (at least 100W power electronic load) is required (to be purchased separately)
4. A tester is required (A3 tester has been purchased)
Operation method:
Insert the trigger into the PD charger, trigger the voltage to 20V, then insert the USB tester, connect the output terminal to a 150W power load, adjust the current to 5A, and test the 100W power
If 100W can be tested, it indicates that the charger is OK
If 100W cannot be tested, it indicates that the charger is NG.
