Most purists will completely condemn the use of anything that requires electricity while spending time in the woods, but they’ll probably still use a lighter or even matches to start a fire. Unless you’ve got a piece of flint in your pocket, you’re willing to accept some elements of modern technology into your wilderness survival kit. The fact is that the 21st century hiker, camper, and hunter has probably got some electronic device in their bag. Whether it’s a radio, camera, GPS unit, or (heaven forbid) a cellular phone, electronics are coming with us into the woods. Until now the only option to keep them charged is more batteries, but BioLite has developed an alternative. The BioLite CampStove converts excess heat into usable electricity while using wood or other flammable material to heat your food.
