Rain or shine, Brunton's Revolt 4000 Power Pack will keep your phone, camera, or GPS beeping and bleeping when you're miles from an outlet. The lithium polymer battery charges quickly and provides over two full phone charges via a standard USB, and the included 3-in-1 connector cord has Micro USB, Apple Lightning, and 30-pin connectors. Life's tough, too, so Brunton built the Revolt with a shock- and weather-proof silicone case and a Vibram underside to keep it from sliding off slick surfaces.
