This portable phone and tablet backup battery by Griffin Technologies is called the Survivor. The name fits, because not only can it survive drops onto concrete from up to 2 meters, but it can also get wet — really wet — thanks to an IP66 water resistance rating. Drop it all you want, and this military-spec battery will continue to charge your smartphone at least three times over, and your iPad or tablet at least once. Grab yours at 16% off for a limited time now. – $50
