I've just unearthed my OpenPandora unit, and (of course) the battery is flat and the power supply is missing.

Am I correct in thinking it's a 3.3v 1A PSU with centre-negative plug? (For that little round port with a central pin on the back of the unit?)

And can anyone recommend a current source of power supplies for the UK/EU (yes, I can use an EU to UK adapter)?

You can use a Sony PSP-adapter, or the USB port.

The PSP appears to be like this:
  • Output Voltage: DC 5V, 1.5A to 2.0A (2000mA max)
  • Total Wattage: 10 Watts
  • Input Voltage: AC 100V – 240V, 50/60Hz (Worldwide compatibility)
  • Connector Type: 4.0mm x 1.7mm DC yellow-tipped barrel plug
  • Inner Pin (Tip): Positive (+) [DC 5V]
  • Outer Sleeve (Earth/Ground): Negative (-) [0V]

While that looks superficially similar, the output voltage seems -- going from the Pandora hacking guide -- as if it would fry the Pandora!

Have you actually used a PSP adapter?

(Also, which USB port would you charge through? The USB-C one, or USB-A?)

I did indeed use a regular Sony PSP adapter for the Pandora (especially when the battery is empty). The mini-USB port works to, but I think it's usually more power limited.

This is the mini-USB:
