The power requirements of the raspberry pi increase as you make use of the various interfaces on the raspberry pi.
Raspberry pi 4 power port. The official and recommended usb c power supply. H 265 4kp60 decode h264 1080p60 decode 1080p30 encode. Raspberry pi 15 3w usb c power supply. An individual gpio pin can only safely draw 16ma.
Unlike the original raspberry pi model b the raspberry pi 2 model b cannot be back powered via the usb ports or at least can t be booted in this fashion. Some raspberry pi models can be powered from a pc or laptop. For raspberry pi 0 3 we recommend our 2 5a micro usb supply.
