BioLite
Is it a portable stove or a gadget charger? How about both. The BioLite ($130) is a compact, portable stove that burns sticks, twigs, pine cones, and other renewable resources instead of petroleum gas, lighting quickly and bringing water to a boil in no time. In addition, it packs a USB port on the front that draws its power from the heat of the fire, letting you charge your phone, GPS, or LED lights miles from the nearest outlet.
