The listing, Never Used Emergency iPod Charger/ Keychain has ended.
Ok, so here's how it works- you plug a 9 volt battery (the rectangle ones) into one side & your iPod into the other & it charges it. It fits both of my iPods, so I'm guessing the connector is standard. I never used it because I lost it not long after I got it & just found it last week. My new iPod holds a charge so well that I don't have a use for it. Very cool item to have around (if you keep track of where you put it). It is also a keychain. Please check out my other auctions. Happy Bidding!
