This is the only emergency charger that can restore the drained batteries of electronic devices by boiling water. Using the laws of thermoelectricity, this unassuming pot becomes a generator, converting heat into electricity anywhere an AC outlet isn't available. Simply fill the 1.4-liter pot with water and heat it on any wood fire, camp stove, or the included propane-powered heating element. As heat passes from the flame to the pot's cool interior, a special plate harnesses the energy, generating a current that recharges handheld USB devices like phones, cameras, headlamps, and GPS units. In tests at the Hammacher Schlemmer Institute, four hours of heat fully restored a dead cell phone to 100% power. The pot includes a 4-oz. camp stove with electric ignition; a 3' long heat-resistant charging cable; a rechargeable lithium-ion battery pack that can charge phones when a heat source isn't available; and adapters for most phones and USB devices. 5" H x 6" Diam.
