JetPower Fuel 230 gram

For best results with your Jetboil Personal Cooking System, use Jetboils JetPower Fuel, a high-performance propane/isobutane four-season blend. Propane provides higher vapor pressure to the fuel for better performance in cold weather. Iso-butane provides more constant pressure as the fuel level gets low. Jetpower 230g canisters will not stow in 1L cook cup, but you get a lot more bang for your buck if you have a bit more space in your pack.
