The Thermodynamic Cell Phone Charger

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.
