What's the big deal about fuel efficiency?

Fuel efficiency translates to weight, space, and money savings. Since Jetboil is up to twice as efficient as conventional stoves, you can take half as much fuel on your trip, thus saving weight. In fact, our Jetpower fuel canister, with 100 grams of fuel, boils as much water with Jetboil as competing stoves do with their big 227 gram canisters. The other big benefit is space savings, since Jetpower canisters nest conveniently inside the cooking cup.
