It never hurts to have an extra canister of fuel along, and it might make a big difference in comfort and safety. This canister is perfect for camping and other outdoor pursuits. Use with KITC062 and KITC063. The 100g canister of Jetpower fuel boils up to 10-12 liters of water. For trip planning, count on 10 liters per canister for some extra margin. If you're melting snow, assume 6 liters per canister. NOTE: In colder temperatures, it will take longer for your water to boil and thus your burner will use more fuel so adhere to the 6L rule.
