Portable backup batteries are essential for breathing life into overexerted gadgetry. Our favorite is the Innergie PocketCell. It's small and easy to store, with a 3,000-mAh battery that can recharge almost every phone (or tablet). But its best feature? Its smart cable, which nests 30-pin, micro- and mini-USB connectors, freeing you from bringing additional cords. [$80; myinnergie.com]
