I made a card to turn any USB C charger into a power supply. Connect to your charger or powerbank, see what it is capable of, and use it to power your load. With PPS, you even have current limit functionality where your charger will drop the voltage to maintain the chosen current! 2 mm thick, $8 a piece to make 100 of them (wasnt easy!)... I love cool PCBs, I hope you find this cool too :D
