Charge your phone, MP3 player and more with AA batteries
Face it. Once the battery dies, your phone is just another hunk of plastic.
Avoid the heartbreak of dead batteries. TuneJuice Universal uses three AA batteries to charge your MP3 player or other USB-charging device. Just pop the batteries into TuneJuice Universal's sliding battery compartment, attach the charge/sync cable that came with your device and your device will charge. We've even included a fresh set of batteries to get you started.
A must-have for travel, camping or anywhere else you might face the bleak prospect of dead batteries.
