Any camp stove can cook your dinner or boil water, but the BioLite CampStove 2 also generates electricity for your gadgets.

Just gather some twigs, light the stove and the USB port will charge your phone while you cook on the portable grill.

Heat from the stove’s smokeless burner is converted into electricity with a thermoelectric generator.

The built-in battery then stores unused power, allowing you to keep charging after the fire has gone out.
