Camp fire…charge your phone…what?! Yes, with the soon-to-be-released FlameStower, you can charge any type of phone just by using the heat from your camp fire and a little water. Their special “Thermoelectric Generator” converts the thermal energy from the fire into useable energy. It takes about as much time to charge a device as it would be to charge it from a USB port on your computer. This handy accessory folds down easily, weighs only 8oz, and can charge phones, GPS devices, digital cameras, just about anything that accepts a standard USB charge.
