Amperage by Pi Model

  • Pi 5: 5V / 5.0A (USB-PD required for full speed).
  • Pi 4: 5V / 3.0A (USB-C).
  • Pi 3 / Zero 2W: 5V / 2.5A (Micro-USB).
  • Pi Zero: 5V / 1.0A.

Note: 'Under-voltage' warnings (lightning bolt icon) cause CPU throttling and SD card corruption. Use a high-quality power supply.
