How long does a camping stove fuel canister last?

If you've ever stood in a gear store staring at a wall of fuel canisters wondering how many to grab for your next trip — you're not alone. How long a camping stove fuel canister lasts is one of the most commonly asked questions we get here at PAST Outdoors, and it's one that catches a lot of people out — particularly those new to backcountry cooking. The good news is that with a little bit of knowledge, it's easy to plan your fuel load with confidence. The answer depends on three key variables: the size of your canister, the output of your stove, and how you're actually using it in the field.

How long does a 100g fuel canister last?

As a general rule of thumb, a standard 100g isobutane-propane canister will last approximately two to three days for a solo hiker who is boiling water twice a day for meals and coffee. Push that to a more capable integrated system running at higher output, and you'll burn through fuel faster, but you'll also boil water more quickly, which partially offsets the difference. The Jetboil TrailCook 1.2L, for example, boils half a litre of water in just 2 minutes 10 seconds and yields around 12 litres of boiled water from a single 100g JetPower canister — impressive fuel economy that directly translates to fewer canisters carried over a long trip.

How you cook makes a big difference

The way you cook also makes a significant difference. Running your stove at full blast to boil water, then immediately shutting it off, is far more fuel-efficient than keeping a gentle simmer going for extended periods. Using a lid on your pot, shielding your stove from wind, and pre-soaking freeze-dried meals can all reduce your fuel consumption meaningfully — sometimes enough to stretch a canister an extra day on a longer trip.

How does cold weather affect fuel canister performance?

Cold temperatures are another important variable. Isobutane-propane mixes perform reasonably well in mild to moderate cold, but as temperatures drop towards zero and below, canister pressure decreases and output suffers. Stoves with a pressure regulator, like the Jetboil TrailCook systems, compensate for this by maintaining more consistent output throughout the life of the canister — not just when it's full and warm. The Soto Windmaster also features cold-weather regulation, making it a strong performer in conditions where a standard canister stove would start to fade.

How many fuel canisters should I carry?

For a two-person trip lasting three to five days, most experienced bushwalkers carry two 100g canisters as a baseline, with a third for longer or more demanding itineraries. If you're cooking more elaborate meals rather than just boiling water, plan accordingly. Check our Jetboil camping stove comparison guide to see specific fuel efficiency data across the range, which can help you plan your canister load more precisely.

Plan smart, cook well

Understanding both of these questions: what stove to choose and how far your fuel will go — is the foundation of smart camp kitchen planning. Get these two right and the rest tends to fall into place, whether you're out for a quick overnight or deep into a week-long traverse.
