Which is power connector polarity?

I would like to adapt a power supplier of mine for my old 3DS (maybe building up something like a dock-station), I found specification of the input current (4.6V, 0.9A), but I have no idea about polarity of the connector. Which is + and wich is - ?

Hi Mick,

For battery connector: When you open the 3DS it tells you which pin is plus and minus on both the 3DS battery slot and the battery itself. You shouldn't need the middle pin to turn it on i don't think.

For the charge port at the back: There are only 2 pins. Set it on a desk with the port facing you. Left is - and right is +
