This tiny thing can fully recharge your phone 1.5 times

Already available for Android and earlier Apple gadgets, this newly redesigned flash drive-sized gizmo now packs enough energy to fully charge the (notoriously power-draining) iPhone 5 more than once, offering comparable backup protection you'd get from much larger and bulkier devices. Plus, you can charge it and your phone from the wall simultaneously, and it lets you know how much juice is left via a special light-up touchpad.
