Packed with games, e-mail, Internet, music, and video, Apple's iPod Touch is one of the best portable time-wasting tools ever conceived, but its built-in battery isn't practical to recharge on-the-go. The Mophie Juice Pack ($99) offers power-hungry iPod Touch owners a stylish and practical means of doubling the device's battery life.
Constructed from matte black plastic with a green interior, the Juice Pack's unique design fits onto your iPod Touch like a case. If the iPod Touch wasn't already so thin, we'd feel the need to complain about how the Juice Pack doubles the total thickness of the player. In truth, we thought the extra bulk added by the Juice Pack made our iPod Touch feel more substantial. The Mophie Juice Pack also adds an extra inch to the bottom of the Touch, obscuring the iPod's dock connection and relocating the headphone jack to the bottom left.
