Backpacking stoves are lightweight and efficient. They're great for emergency kits, camping and, of course, backpacking. Backpacking stoves are easy to use, great for boiling water quickly and use only a small amount of fuel. Their fuel canisters can last anywhere from 2 days to 1 week, depending what size you purchase and how many meals you cook using the fuel. Stoves and fuels can be purchased at most camping/outdoor recreations stores or online.
