Backpacking Stoves: How to Choose
Being an Outdoor Guide means that everyone asks you questions. Here are some tips and tricks that you can use!
Backpacking stoves are light, reliable and support the Leave No Trace ethic. In many backcountry areas, open fires are prohibited due to forest-fire danger or the scarcity of available firewood, so a stove is your only option.
For most backpackers, your main decision will be between the 2 broad stove categories: canister fuel vs. liquid fuel. You may also want to consider one of the growing number of alternative-fuel options now available.
Here are some quick recommendations:

What’s Your Preference: Boiling or Simmering?
Some backpackers want a stove that boils water rapidly for rehydrating freeze-dried meals or melting snow for water. Others want a stove that offers more precise simmering control for gourmet-style cooking.
Manufacturers provide estimates of how quickly their stoves take water from ambient temperature to boiling. Unfortunately, no standardized test for determining water-boiling speed exists, so these estimates may not offer true apples-to-apples comparisons.
Some general boiling and simmering guidance:
- Integrated canister systems boil water fastest while also using minimal fuel. Simmering is possible, but it’s an afterthought in their designs.
- Canister stoves boil water quickly, and some models are good to excellent at simmering—great for camp gourmets.
- Liquid-fuel stoves boil water very quickly, even in cold weather. Simmering ability varies widely by model.
- Alternate-fuel stoves are intended primarily for boiling, though they are slower, sometimes by minutes. The BioLite CampStovemodel offers decent simmering capabilities.
Group Size
If camping in a group of 3 or more, it’s smart to bring more than 1 stove. Otherwise, if you’re hungry and last in line for that single stove, the wait can seem interminable. With modern stoves being so small and light, it’s not uncommon for each backpacker to bring their own stove.
Trip Length and Estimating Fuel Needs
In his book, The Ultimate Hiker’s Gear Guide, author Andrew Skurka estimates a typical 8-ounce fuel canister should heat about 30 pints of water. That’s about 60 cups. A freeze-dried meal usually requires 2 or more cups of water to rehydrate, so a canister is a good bet for 15 to 20 meals—barring cold temps, high winds or similar factors that could diminish stove performance.
Liquid-fuel stoves use refillable fuel bottles, and you can peek inside to gauge your fuel supply. With canister stoves, you can only shake the sealed canister and guess how much fuel remains. So carrying a spare is beneficial even though that means more weight and bulk in your pack.
Skurka’s calculation—60 cups of water heated per 8 ounces of fuel carried—is a good estimate for any canister or liquid-fuel stove. Your results, of course, may vary. Field experience will help you calculate how much fuel is needed for your style of cooking.
There you have it. The above discussion covers the basics of backpacking stove shopping. For a closer look at your choices, read on:
Canisters run on pre-pressurized gases: isobutane (primarily) and propane. Isobutane burns hot and clean, and in colder conditions it outperforms conventional butane. The canister self-seals when the stove is detached, eliminating the possibility of fuel spills.
Fuel canisters connect to stoves in 2 ways:
Upright: The stove screws into the top of the fuel canister. This is the smallest, lightest option. Downsides? Tall profile is prone to tip-overs; small pots don't hold large pots well.
Low-profile: The burner sits on its own base and a fuel hose connects it to the canister. Canisters can be inverted to improve cold-weather performance; large pot supports improve pot stability. Cons? It's a bit heavier and bulkier.
The biggest drawback is that upright canisters depressurize in the cold (32°F or lower) leading to weak or no flame. Normal pressure resumes when the canister temperature is increased.
Tip: In cold weather, keep the canister warm by putting it in your sleeping bag at night or hiking with it in your jacket pocket. Place a bit of foam underneath it when cooking.

Other considerations:
- The Jetboil CrunchIt Tool allows you to recycle your spent fuel canisters. (Previously, they were often considered hazardous waste.) Check with your local recycler to ensure acceptance.
- Warning: For stoves that attach directly to the canister, a windscreen must not be used because it traps excessive heat. This creates the potential of fuel exploding.
- Low-profile canister stoves (those that separate the canister from the stove) may allow the use of a windscreen to improve efficiency.
- Some models have a built-in pressure regulator to provide consistent heat output throughout the life of the canister. This improves cold weather performance, too.
- Stabilizers, sometimes sold separately, can be attached to the bottom of fuel canisters to reduce the chance of tipping over.
Tip: Stormproof matches should always be carried in case the Piezo igniter fails.
Integrated Stove Systems (Canister)
One popular option for the canister-stove shopper is an integrated stove system such as the Jetboil series.
With this approach, the canister stove is paired with a cooking pot (and optional accessories such as a French press for coffee making) designed to work specifically with that stove.
Here's how these compare with traditional canister stoves:

What fuels do liquid-fuel stoves use? All run on so-called white gas, or naphtha, as it’s known in the fuel industry. It is a highly refined fuel processed to leave few or no impurities in the final product. It burns hot and clean, performs well in below-freezing temperatures and, compared to the per-ounce cost of canister fuel, is much less expensive.
Some backpacking stoves (a few camping stoves, too) are multifuel stoves. Depending on the model they may also operate on kerosene, jet fuel, diesel or non-oxygenated unleaded auto gasoline. This can be useful for international travelers who face limited fuel choices outside the U.S.
None of these fuels are as purely refined as white gas, and any impurities they carry may, over time, clog stove parts such as the fuel tube.

White gas is known to degrade over time. The fresher the fuel, the less likely it will cause clogs. If using aged white gas (not advised), use a filter to strain out any tiny sediment that might be lurking within. If older white gas shows a tint of color, that’s often a sign it’s past its prime.
Two potential downsides to liquid-fuel stoves:
1. They typically require periodic maintenance, such as cleaning the fuel hose or replacing O-rings (in the stove and on fuel bottles).
2. Most require priming, which involves igniting a few drips of fuel in a cup below the burner, creating a small flame that preheats the fuel line. This enables the stove to convert liquid fuel into a vapor.
Multifuel Stoves (Liquid Fuel)
Some liquid-fuel stoves can accommodate various fuels including some or all of the following: white gas, unleaded auto gasoline, kerosene, jet fuel and diesel. These stoves can cost a bit more and require more maintenance but the added fuel versatility makes them a great choice for international travelers.

Wood-burning stoves burn twigs and leaves you gather in the backcountry. So you carry no fuel, a nice idea for longer trips. A recent addition to this category is the BioLite CampStove, which generates electricity while operating—enough to charge a mobile phones or other small gadgets via a USB connection. It can even be outfitted with the optional BioLite Portable Grill. Downside: This stove is not the lightest or most compact option, and finding dry fuel during wet weather can be challenging.
Denatured alcohol stoves have few or no moving parts to worry about, weigh very little and burn silently. Alcohol does not burn as hot as canister fuel or white gas, so it takes longer to boil water and requires more fuel. Alcohol fuel can be hard to find outside the U.S. These stoves appeal most to ultralight backpackers.
Solid-fuel tablet stoves are another popular choice with ultralight backpackers thanks to their compact size. Also good for emergency kits. Downside: They are slow to bring water to a boil.
Once you've decided on a stove category, compare models using the following performance attributes:
- Burn time: how long a stove burns using a given amount of fuel.
- Average boil time: time required to bring 1 liter of 70°F water to a boil (based on an average of 3 timed boils).
- Liters of water boiled (per 100g of fuel): the "miles per gallon" rating for fuel efficiency at full stove power. Note: When stoves are operated at less than full power, they are even more efficient.
- Pot stability: how well a stove's support arms hold a typical cooking pot.
- Stove stability: the stability of a stove's design.
- Ease of operation: what stoves are the easiest to operate?
Keep in mind that lab performance is almost always better than performance in the field (i.e., a stove that takes 3 minutes to boil 1 liter of water in a lab may take significantly longer in cold, windy conditions).
Q: Are the various brands of fuel canisters interchangeable? For example, can I use my Gigapower fuel on a Jetboil stove?
A: Most canisters feature a Lindal valve with standardized threading. This allows fuel canisters to be interchangeable between brands, though manufacturers generally like to recommend using their own brand of fuel with their stoves.
Q: How difficult is priming? What are the steps?
A: Priming is required for liquid-fuel stoves only. Its purpose is to preheat (and vaporize) a small quantity of fuel to ensure proper stove ignition. While priming is not difficult, you should refer to your owner's manual for step-by-step instructions.
Q: What is a Piezo igniter?
A: Pronounced pee-A-zo, this is a push-button spark producer (generated by a crystal) found on some canister-fuel stoves. It's a handy feature, especially if your matches are lost or wet.
Tip: Always carry stormproof matches as a backup.
Q: Can I use unleaded auto gasoline in a multifuel stove?
A: Gas stations in many parts of the U.S. carry only oxygenated gasoline during winter months to reduce emissions. That’s helpful to the environment, but additives in oxygenated gasoline can damage your stove. Outside of an emergency, it’s best to stick to whatever fuels the manufacturer recommends.
Any stove:
- Warning: Do NOT cook inside tents or enclosed spaces. This can cause carbon monoxide poisoning and create a high fire risk.
- Check all fuel lines, valves and connections for leaks before lighting your stove.
- Operate your stove on the most level surface possible.
- Use a lid when cooking.
Canister stoves:
- New fuel canisters usually contain a small amount of air near the top; after this bleeds off, the fuel will flow and ignite. If the stove tips, a large yellow flame-up may occur.
- Never use a windscreen with a canister stove.
- Always carry stormproof matches in case the Piezo igniter doesn't work.
Liquid-fuel stoves:
- Don't fill a fuel tank to the brim. Fuel expands as it warms, so leaving an air space prevents excessive pressure buildup.
- Empty the fuel tank before storing your stove for several months or longer.
- If using auto fuel, avoid the oxygenated gas found in some areas of the U.S., especially during winter. It breaks down vital stove components.
- Use alcohol for priming. It helps to keep your stove soot-free.
- Use a windscreen.
- Consider using a heat exchanger for cold weather or extended trips—it promotes faster boiling and saves fuel.
- Don't spill fuel on bare skin. In extreme cold, this can cause frostbite due to the rapid evaporation of fuel.
