4. Pressurized Gas Stoves
Store-bought cylinders of propane, butane, or blended fuels are the fuel source for this group of stoves. These are very efficient, easy to operate and clean. They tend to have a higher price tag, though butane cook stoves can be found as low as $20 USD at international grocery stores. Their chief problem would be the difficulty finding the right fuel canisters in remote areas, during an emergency, or in the aftermath of a crisis. That said, something like a Jetboil is a Cadillac of camp stoves. It's quick to boil, lightweight and very well engineered. If you have a cache of fuel canisters at your disposal, you'll really enjoy the speed and convenience of this group.
