The PowerPot is a thermoelectric generator that uses heat to generate electricity. The PowerPot has no moving parts or batteries, and since the thermoelectric technology is built into the bottom of the pot it can produce electricity from a wide variety of heat sources. Simply add water and place the PowerPot on a fire (e.g. wood, propane, butane, alcohol, gas) and it will start generating electricity within seconds. Just plug in the high temperature cable to the back of the pot and watch your USB devices safely charge from a fire.
