Oh, nice, thanks for that link and info! As you mentioned, the page even lists the output plug polarity¹ it requires (centre positive)!
EDIT: Just realized that’s the same size barrel connector used for Sony’s PlayStation Portable², PlayStation TV³, etc., and the power supply⁴ those devices come with is 5V ⎓ 2A and have a centre positive polarity, so it seems like they’ll be perfect for use on the Orange Pi One.

- wyldfire 10y agoDon't DC power jacks come keyed for at least voltage/polarity? If not -- why‽
- khedoros 10y agoThey come in various shapes, varying on inner diameter, outer diameter, and length. Smaller connectors may tend to be lower voltage, but that's certainly always true. There are several standards, and at least some of them specify voltage ranges for particular sizes, but there's no universal standard.
