The DW-SM-45W Wood Burning Stove Thermoelectric Generator can be placed on the top or mounted onto the side wall of a stove to generate electricity to charge a battery, power a 12V DC device, or charge a cell phone with it's handy 5V DC USB output. The DW-SM-45W 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 it's size.
If you have a wood stove at your house or camp, this is great micro-power system. Connect multiple units and subsidise your heavily taxed solar system in the winter months.
