This protective case slips easily and snugly over your video iPod and has a built-in high-capacity lithium polymer battery pack designed to extend the playback time of the 60GB i604 player up to 55 hours, 275% more playing time than the standard playback life of a video iPod. The soft silicon skin provides a firm grip and gentle protection against scratches, and the lightweight protector has a stainless steel base that guards your iPods pin connector while allowing it to be plugged in for recharging without having to remove the cover. The leak-resistant shell resists overcharging, has slots to accommodate USB and headphone connections, and does not interfere with deft control of your iPods functions. Specify Black or White. 2 1/2" H x 1 3/4" W x 1" D. (1/2 lb.)
