First, try USB charging. It is slower than AC charging but should help a little identifying if it is a problem with the Pandora, battery, or the charger. If you have a PSP or know someone who does, the Pandora uses the exact same AC charger. If you can find a PSP charger then you will be able to test for sure whether the problems you're having are with the charger or the Pandora. You can find official Sony PSP chargers for $5-$10 these days from a lot of places, so no need to buy one from EvilDragon.
