hi, Just wondered what amps the USB on the back of a normal white wii can throw out? don't want to overload it. Checked the search, even nintendo site, and no tech info at all I know it powers my 320gb external HDrive, so that's about 0.7-1 amp. I've checked the voltage myself, it is giving me 5.07/8volts, which I may need to power other things. Many thanks in advance!
