We got this A/C adapter for my daughter's LeapPad. When we bought the LeapPad, we were not aware that it was not a rechargeable thing. So, we have eaten through a LOT of batteries in recent weeks. This will hopefully help when we run out of batteries and can't make it to the store for more. (Much cheaper in the long run!!)
