Charging a USB powered device is possible by using thermoelectric plates. Basicly it is a plate that produces electric currents when one side of the plate is hotter then the other cooler side of the plate. This is how BioLite Camp Stove is able to produce electricity. At the same time you are charging your USB smartphone or tablet you can be cooking your dinner on the camp stove at the same time. Saving space by not carrying separate charging sources and combining your camp stove with it is a great way to save space as it is increasing efficiency.
