Plugging a PS2 adapter into a PSP (even if forced) feeds 8.5 V into a 5 V device—instantly frying the power circuit.

Correct PSP Charging Options

  • Official PSP AC Adapter (model varies by region/PSP model).
  • USB Cable + 5 V USB Charger (PSP-1000/2000/3000/E1000 via Mini-USB; PSP Go via proprietary cradle/USB).
  • Multi-voltage Travel Adapter with correct tip and 5 V / 2 A output.
