Recommended/Tested USB-C Charger

• UGREEN 100W - PPS 3.3 - 21.0 @ 3A
• ANKER 737 (GaN Prime 120W) - PPS 3.3 - 11.0 @ 3A
• UGREEN 140W - PPS 3.3 - 21.0 @ 5A
• AOHI Magcube 140W - PPS 3.3 - 21.0 @ 5A
• Anker 737 Power Bank - PPS 3.3 - 21.0 @ 5A

Many Anker charger/power banks do not include PPS capability in their marketing document. Their IQ3 and IQ4 standard support PPS up to at least 11V. IQ1 and IQ2 has not been tested.

Testing result

15 min stress test at 20V 5A showing that the board temperature rises to 62C with the board in still air. This is within the working temperature (85C) of all ICs on the boards.
