Jetboil Jetpower Fuel – 450 g

At 450 g, this is the largest JetPower canister Jetboil offers, mixing 73% isobutane with 25% propane for four-season reliability and rated to boil approximately 48 litres of water — around four times the yield of the 100 g size, though obviously at a proportionally higher weight to carry. The Lindal EN417 valve keeps it compatible with all Jetboil stoves as well as most other screw-on gas systems on the market, so switching between camp stove brands does not require a different fuel source. A listed burn time of 150 minutes gives a rough sense of continuous stove runtime on this canister alone, useful for planning fuel needs on longer trips or for group cooking where a single large canister is more efficient than carrying several smaller ones. Because of its size and weight, it makes more sense for basecamp use, extended expeditions or shared cooking among several hikers than for solo ultralight thru-hiking, where the 100 g or 230 g canisters keep pack weight lower between resupply points.
