In Pictures: Cool iOS accessories for iPhone and iPad unveiled at CES 2013

Innergie announced the PocketCell Duo, a rechargeable battery pack that can repower your iPhone and iPad at the same time (it also works with Android devices). It's equipped with a 6,800mAh battery, twice the power of the previous model, and two 2.1-amp USB power ports; it's 3.75 x 1.75 x 1 inches, and weighs 4.7 ounces. For the newest iOS devices with Apple's Lightning connector, Innergie will offer a tip that plugs into its existing Magic Cable Duo and Trio charging cables. The battery can fully charge a tablet once or a smartphone four times on a single charge; or extend a tablet's life for up to seven hours, and of a smartphone up to 30 hours.
