Leave your fuel canister at home—you can cook your camp meals, charge your gadgets, and reduce your carbon footprint at the same time with the BioLite CampStove (pictured left, $130; biolitestove.com). Just collect a pile of twigs, pine cones, or wood pellets into the stove’s fuel chamber, light ‘em up, and cook over natural heat. Jets circulate air through the chamber to gasify the wood for clean combustion that boils a liter of water in 4.5 minutes. No outlet in your neck of the woods? No problem. The stove’s thermoelectric generator transfers heat to electricity to charge (albeit slowly) your gadgets via a USB port. For greater culinary versatility, tack on the Portable Grill ($60; biolitestove.com) which cooks up to four burgers or six sausages with high, medium, or low temperature zones.
