it should work. this is a new item. one of those promotional gifts from companies during an event. if it works for all kinds of devices, I can't say as it didn't come with instructions but I would assume it works for example phone chargers and camera chargers if they are USB plugs
Well I'm willing to bid all my credits for it! I need one for when I travel from PA to MI. It's 11 hr drive and my ipod always dies half way through, so I've been wanting one of these!
