Hello! My brother got a free MP4 Player from Staples. Its only got a Gig on board. And it came with a usb adapter to use, so he can charge it using a Plug (3Pin) I was wondering whether it was safe to use with my iPod touch 2G? What i found on it: S.E.C tm www.sec-brand.eu CHARGER RoHS MODEL: CH-L02 INPUT: AC100-240V 50/60Mhz OUTPUT: DC5V% 450 -+ (The + was above the -) 550A USE ING IN ROOM So is this ok to use with my iPod Touch?
