Portable Cooking Gear: How to Pick a Stove and Fuel That Still Works in the Cold

Choosing portable cooking gear is mostly simple until the temperature drops, and then one decision starts mattering a lot more than the others. The stove that has worked fine on every summer trip you have taken can sit there hissing weakly in a January outage while the water in the pot stays stubbornly lukewarm.

That failure is not a defect. It is chemistry, and it is predictable enough that you can pick your way around it. Here is how the fuel types actually behave, what the safety rules are and where they come from, and how to plan fuel for an outage rather than a weekend.

Why do canister stoves stop working in the cold?

Because a canister stove runs on vapor pressure, and vapor pressure comes from the liquid fuel boiling off inside the canister. Below the fuel's boiling point, that stops happening. The burner starves.

NOAA's CAMEO Chemicals database gives the boiling points in Fahrenheit for all three fuels used in consumer canisters:

• n-Butane: 31.1 degrees F

• Isobutane: 10.8 degrees F

• Propane: minus 43.8 degrees F

The NIST Chemistry WebBook independently places isobutane's normal boiling point at 262 plus or minus 2 Kelvin, which is about 11.9 degrees F, agreeing with CAMEO within its stated uncertainty.

Line those numbers up against your weather and the picture gets clear fast. A pure butane canister, the kind sold for tabletop stoves, is finished at just below freezing. The standard 80/20 isobutane and propane blend that the National Park Service sells at Isle Royale keeps working into the teens because the propane fraction is still vaporizing and holding pressure up. A dedicated propane cylinder goes down to temperatures nobody is cooking in.

I want to be honest about one thing here, because it gets overstated everywhere else. No government, university or standards body publishes a specific temperature at which a canister stove quits. What they publish are the boiling points, and the conclusion follows from the physics rather than from a citation. Below its boiling point, the liquid stops boiling off vapor. Everything else about canister behavior in cold, including how pressure drops as the canister empties and how the canister cools itself during use, comes from manufacturer material rather than from any authority I can point you to.

Practical version:

• Above 40 degrees F: a canister stove is fine.

• 20 to 40 degrees F: use an isobutane and propane blend, and expect reduced output.

• Below 20 degrees F: go liquid fuel.

Which stove is actually best for cold weather?

Liquid fuel, and the National Park Service says so from the place that would know. Denali National Park's mountaineering equipment guidance states that white gas stoves have been the staple for decades and perform reliably in cold weather and at high altitude, while cartridge stoves perform worse in cold, their cartridges are less widely available, and they are less efficient for melting large batches of water and cooking for a group. NPS notes some groups carry a cartridge stove as a backup or summit-day emergency stove, which is a sensible way to hold both.

The University of Maine's outdoor leadership curriculum agrees and adds the tradeoffs. White gas stoves are great in cold conditions, easy to clean, field repairable, with cheap accessible fuel and refillable bottles that produce less landfill waste. The downsides are that they are slower to light and require pumping to pressurize.

On canister stoves, UMaine is fair: inexpensive, easy, good for small groups and boiling water, but weaker for baking and simmering, and the burners are generally small and have a hard time evenly heating pots or pans larger than a liter. The canisters cannot be reused and have to be disposed of. Decide what you are actually cooking before you buy, because it drives the pot size as much as the stove does. Blanching a batch of foraged greens, for one, needs a hard rolling boil rather than a simmer, which is the first step in most recipes using wild plants.

UMaine also offers the line I would put on a wall: in the winter a stove is considered a piece of safety equipment that you should always bring.

The NPS Denali guidance adds two habits that transfer to any cold-weather cooking: bring multiple stoves plus repair kits and the knowledge to use them in the field, and use a flame-resistant cook board to give the stove a level platform.

Where can you safely run a stove?

Outside. That is the whole answer, and it is the one rule on this page I would not bend for anything.

CDC's guidance during a power outage is explicit: never use a charcoal grill, hibachi, lantern, or portable camping stove inside a home, tent, or camper. CDC's carbon monoxide page says never use a portable gas camp stove indoors and never burn charcoal indoors. FEMA's power outage hazard sheet says to use generators, camp stoves or charcoal grills outdoors, at least 20 feet away from any building openings.

The tent part is where people argue, so here is the evidence. A CDC MMWR report on carbon monoxide deaths associated with camping in Georgia documents two incidents in March 1999. In the first, a family brought a still-burning propane gas stove into a zipped-up 10 by 14 foot tent for warmth. Four people died, ages 51, 10, 9 and 7, plus the family dog, with postmortem carboxyhemoglobin levels of 50, 63, 69 and 63 percent. In the second, a charcoal grill was moved into a zipped-up tent after outdoor cooking, and two people died with levels of 68 and 76 percent. For scale, CDC notes typical COHb averages about 1 percent in nonsmokers and 4 percent in smokers.

The editorial note in that report contains the sentence that settles the argument: opening tent flaps, doors, or windows is insufficient to prevent build-up of CO concentrations from these devices.

The scale of the problem, from CDC: more than 400 Americans die each year from unintentional carbon monoxide poisoning not linked to fires, more than 100,000 visit an emergency department, and more than 14,000 are hospitalized. CPSC's 2022 consumer-product figures count 274 unintentional non-fire CO deaths from products under its jurisdiction, including 18 from charcoal and charcoal grills and 11 from grills and camp stoves.

The exposure thresholds, from the NIOSH Pocket Guide, in case you want to know what the numbers mean: the NIOSH recommended exposure limit is 35 ppm as an 8-hour average with a 200 ppm ceiling, the OSHA permissible exposure limit is 50 ppm, and the immediately dangerous to life or health level is 1,200 ppm.

CDC lists the symptoms in this order: headache, dizziness, weakness, upset stomach, vomiting, chest pain and confusion, and notes they are often described as flu-like. CDC's clinical guidance gives the detail that actually distinguishes it: no fever associated with the symptoms, a history of exposure, and multiple people with similar complaints.

On alarms, CDC recommends battery-operated or battery backup CO detectors near every sleeping area, checking batteries when you change the clocks each spring and fall, considering a model with a digital readout, and replacing per manufacturer instructions or every 5 years. CPSC adds that interconnected alarms are best so that when one sounds they all sound, and the instruction that matters most: never ignore an alarm when it sounds, get outside immediately and call 911.

Can you use a wood stove during a fire ban?

Usually not, and the rule agencies apply is clearer than most people expect: it comes down to whether the device has a valve that kills the flame instantly, and whether it produces ash.

North Cascades National Park's campfire ban notice states that gas or propane stoves, grills or lanterns are permitted in campgrounds and wilderness areas for cooking provided there is no flammable material within three feet of the device and the stoves are equipped with an on-off switch or valve capable of immediately extinguishing the flame. The ban itself covers igniting wood, briquettes or any fuel in fire pits, fire pans and barbecue grills, and applies to anything that produces ash, including charcoal grills. Even propane fire pits are not allowed during the ban, because they are not cooking devices.

The Sequoia National Forest restriction draws the same line from the other side: a valid California Campfire Permit does not exempt you from the prohibitions, but permit holders may use a stove or lantern that uses gas, kerosene, jellied petroleum, or pressurized liquid fuel and has a shut-off valve, used at least five feet from flammable materials.

Under normal conditions, though, small wood stoves can be legal. Isle Royale National Park permits small twig wood-burning stoves with a firebox of roughly 7 inches or less that contains fire and embers and leaves little ash, using dead and down twigs only, no breaking branches from trees. Isle Royale also permits white gas and liquid-fuel stoves, isobutane and propane canister stoves, and alcohol stoves burning denatured alcohol, while prohibiting charcoal-burning and solid-fuel-burning stoves.

So the same twig stove can be legal in one park and banned in another, and legal in one park in June and banned there in August. Restrictions are issued per unit and per stage. Check the actual order for the place you are going.

The University of Maine adds a non-legal consideration: wood and biomass stoves are not permitted in all areas because they are not very Leave No Trace friendly, and bringing your own wood is not a great practice either.

What about alcohol stoves?

They work decently in low temperatures, they are easy to improvise, and they have one genuine hazard that makes me cautious recommending them to beginners.

The University of Maine states it directly: alcohol stoves can be dangerous as they are hard to put out, having no off switch, and a spill of denatured alcohol fuel can quickly lead to an invisible fire. The blue flame is hard to see in daylight, which is the whole problem.

The refueling hazard is documented by CPSC, though in a different product category. CPSC's consumer alert on alcohol and liquid-burning fire pits warns that a small flame in the fire pit can be hard to see and can ignite alcohol or other liquid fuel as it is poured, and that flame jetting can occur when refilling if any flame is present, causing an explosion that propels flames and burning liquid onto the consumer or bystanders. CPSC associates those products with two deaths and at least 60 injuries since 2019. An earlier CPSC recall of pourable gel fuel documented 65 incidents, 2 deaths and 34 hospitalizations with second and third degree burns.

Those are fire pits, not stoves, but the physics of pouring fuel onto a flame you cannot see is identical. The USFA's rule for fire pits transfers cleanly: never add liquid fuel after trying to start a fire. With an alcohol stove, that means letting it burn out completely and cool before you touch the fuel bottle.

How should you store fuel?

Outside the house, upright, cool, and away from anything with a pilot light.

For propane cylinders, the North Carolina Department of Agriculture and Consumer Services LP-Gas section states as a matter of state law that containers are to be stored outdoors, standing upright on the foot ring, and specifically not indoors and not under the house in a crawl space. Keep them away from heat and out of the sun, and not beside a southern-facing masonry or dark wall.

The Minnesota State Fire Marshal gives the hard numbers from NFPA 58, and they are stricter than most people assume: in residential occupancies, including attached and detached garages, the maximum container size is 1 pound and the maximum is 2 pounds per dwelling unit. Cylinders larger than 1 pound must not be stored or used indoors at a residential property. That rules out a 20-pound grill cylinder in any home garage. Minnesota also notes that valves stay closed in storage, cylinders over 1 pound are stored upright so the pressure relief valve stays in the vapor space, and that excessive temperature rises will cause venting due to expansion.

For liquid fuel, CPSC's fuel container guidance says to use a child-resistant portable fuel container holding five gallons or less, store containers in well-ventilated cool areas only, keep them out of children's reach, and not keep gas cans in a house or basement. Avoid storing near fuel-burning appliances, open flames, pilot lights, stoves and heaters. The US Fire Administration's version is shorter: store oil, gasoline, paints, propane and varnishes in a shed away from your home.

One note on honesty: the commonly repeated 120 degree F ceiling for propane storage is not something I could verify on any government or NFPA page. The sourced version of that concern is Minnesota's venting language and North Carolina's instruction to keep cylinders out of direct sun. Keep them cool and shaded and you are following the actual guidance.

How much fuel do you need?

Here is where I have to tell you that the number you want does not exist in any authoritative source, and that the honest approach is to calculate your own.

I found exactly one government fuel-planning figure. The National Park Service's Denali mountaineering guidance plans one gallon of white gas per person for a three-week expedition, plus one extra gallon for the team, and notes that use varies by team depending on meal planning and water needs. That works out to roughly 6 fluid ounces per person per day, but that is my arithmetic, not NPS's, and it describes an extreme case where nearly all water is melted from snow. A summer backpacker boiling two liters a day is nowhere near it.

So build your own estimate from the thing you actually control, which is how many liters you need to boil. Start with CDC's water treatment figure, since that is usually the biggest draw: bring clear water to a rolling boil for 1 minute, and for 3 minutes at elevations above 6,500 feet. Boiling is effective against all major germ types, including viruses, bacteria and parasites such as Cryptosporidium and Giardia. If the water is coming off a roof or out of a rain barrel rather than a tap, look at rainwater filtration methods before any of it goes in the pot.

Count the liters per person per day for drinking, cooking and cleanup. Boil that many liters at home with the stove and fuel you plan to carry, time it, and weigh or measure the fuel you used. Multiply by your days, then add half again for cold weather, wind and the pot you will inevitably have to reheat. That is a real number for your gear rather than a guess from someone else's.

What about cooking during a power outage specifically?

Same stove rules, plus food safety, because the two problems arrive together.

FEMA's power outage hazard sheet gives the thresholds: discard refrigerated food exposed to temperatures of 40 degrees Fahrenheit or higher for more than 4 hours, and discard food with unusual odor, color or texture. Refrigerated food stays cold about 4 hours, and a full freezer holds a safe temperature about 48 hours. Which means the pantry is what actually carries an outage, so it pays to know how to organize shelf-stable food before the power goes out.

CDC supplies the half-full number: a full freezer keeps food safe for 48 hours, 24 hours if half full, if you do not open the door. Food can be refrozen or cooked if it still contains ice crystals and feels as cold as if refrigerated. Food that never needed refrigeration in the first place, like jarred goods kept for long-term food storage, sidesteps the clock entirely.

And CDC's rule that overlaps directly with this article: never use a gas range or oven to heat a home. Cooking on it is what it is for. Heating with it is how people die.

Frequently asked questions

Why do canister stoves stop working in cold weather?
Because the fuel has to boil to make vapor pressure, and below its boiling point it stops. Per NOAA CAMEO Chemicals, n-butane boils at 31.1 degrees F, isobutane at 10.8 degrees F, and propane at minus 43.8 degrees F. Once the canister itself falls below the boiling point of its blend, the liquid stops producing usable vapor and the burner starves.

Can you use a camp stove indoors or in a tent?
No. CDC states plainly: never use a charcoal grill, hibachi, lantern, or portable camping stove inside a home, tent, or camper, and never use a portable gas camp stove indoors. A CDC MMWR report on Georgia camping deaths notes that opening tent flaps, doors, or windows is insufficient to prevent buildup of carbon monoxide from these devices.

Which stove is best for winter camping?
A liquid-fuel stove. The National Park Service's Denali mountaineering guidance says white gas stoves perform reliably in cold weather and at high altitude, while cartridge stoves perform worse in cold and are less efficient for melting large batches of water. The University of Maine's outdoor leadership curriculum says white gas stoves are great in cold conditions.

Are wood-burning backpacking stoves allowed during fire restrictions?
Usually not. Agencies draw the line at whether a device has a valve that kills the flame instantly. North Cascades National Park permits gas or propane stoves with an on-off valve during a campfire ban, while the ban applies to anything that produces ash, including charcoal grills. Restrictions are issued per unit and per stage, so check the specific forest or park order.

How long do you need to boil water to make it safe?
CDC says to bring clear water to a rolling boil for 1 minute, and for 3 minutes at elevations above 6,500 feet. Boiling is effective against all major germ types including viruses, bacteria and parasites such as Cryptosporidium and Giardia. Let the water cool before use to avoid burns.

Where should you store propane cylinders?
Outdoors, upright on the foot ring, out of direct sun and away from heat, per the North Carolina Department of Agriculture and Consumer Services. The Minnesota State Fire Marshal, citing NFPA 58, says cylinders larger than 1 pound must not be stored or used indoors at a residential property, which includes attached and detached garages.

Pick the fuel for the coldest temperature you will actually cook in, keep the stove outside, and know your own boil times before you need them. That is a short list, and it holds up. You never know, but you can always be ready.
