I have read here that is possible to charge you pi4 with 3rd party chargers that supply 5V 3A.
I am wondering if I can use this 20W charger, which can deliver differnet voltage level (5V/3A, 9V/2A, 12V/1.5A, 9V/3A, 11V/1A), without damaging the pi4?
Can I be sure that the charger will output the correct voltage/ampere for the pi?
How does the pi4 handle the usb-c negotiation?
From the official pi schematic, the usb-c specification (I am refering to table 4-24) and this post it seems that there are two 5kΩ resistors which tell the charger that the pi4 needs 5V. Is my assumption correct?
