Ever hear of thermoelectric power? That's OK, you don't have to know how it actually works to use it. You just need a way to turn heat into energy and that's exactly what the PowerPot does: boiling water in this special receptacle will actually charge up your phone, tablet or any other USB-powered handheld device.
The $149 PowerPot works with any heat source, so you don't need a special stove: Electric (although that would be silly, no?), gas or a plain old fire will do the trick because you're just boiling water.
