1: This PD parody uses the 2721 hardware PD chip, which cannot be upgraded, cannot change voltage, and cannot be solved with compatibility issues. 2: Not all USB-C power supplies can support all voltages, if the power supply does not support the requested voltage, the next lowest voltage will be supplied, the module just performs PD negotiation and passes the output. 3: To use more than 3A you will need to use an electronically marked Type C cable, a genuine USB PD power source is required, will not work with QC chargers only..
