Hi.
I have a 20V battery connected to my pcb. I need a 5V/3A output, so I am going to solder a 5V step down module to my circuit.
Since I know a USB C cable can handle 3A, I am going to wire a USB C cable to the output pins of the step down module. At 5V/3A, that will be a total of 15W going through the cable. I am not sure if the same cable type can be used for the input since the voltage from the battery is 20V. Making it 20V*3A = 60W going in to the step down module through the cables.
I have seen AWG charts, and they don't mention anything about voltage or wattage. How do I know if the USB C cable will be safe to use for the input of the step down module?
