my rpi kit had a 1.5 amp power supply. if yours still has a sticker on it read the output should be 5v and current like 650mA or 1.5Amp or whatever, you should try to have at least 3A. you can get a usb microB to 1.1mil barrel adapter if you got the money, that way your supply is not modified. your barrel , i think , is 3.5mm o.d. x 1.35mm i.d. and the link you posted has that.
