The DW-DF-15W Camping Cook Stove Thermoelectric Generator can be placed on the top of an open flame from a propane stove or grill to charge a battery, power a 12V DC device, or charge a cell phone with its handy 5V DC USB output. The DW-DF-15W is supplied with 2 cables: one for charging a battery, the other supplies a 12V DC automotive output and a 5V DC USB port.
To ensure an adequate temperature difference necessary for power generation, the low temperature side of the Thermoelectric Generator is cooled with 2 electric fans. The fans help circulate heat in the room. This unit is lightweight and provides a lot of output power for its size.
If you have a propane or natural stove at your camp or tent site, this is great micro-power system.
