I seriously believe this thing has dammaged my IPod. It would lock up my IPod when I was listening to it while charging. It also reads as charged within about 4-5 minutes of charging, but when I unplug it, is back down to only a quarter charged. I ended up throwing this in the garbage, the great price is not worth ruining an expensive IPod. Also, this item does not have the approved by UL stamp on it and it gets extremly hot while plugged in, even when its only been plugged in for about 20 minutes or less. BAD PRODUCT
