How Long Does One Butane Cartridge Last? Burn Times by Stove Type (India 2026)

Quick answer: one 225 g butane cartridge lasts 1 to 1.5 hours on a full flame, 2 to 2.5 hours on medium, and 2.5 to 3+ hours on a low simmer — a two- to threefold difference from the same can, decided almost entirely by the flame knob. On a medium flame that is about 4 to 5 everyday meals. Can size is the second factor and a much smaller one: a 220 g can gives roughly six minutes less cooking than a 225 g can, and an 8 oz (227 g) can is effectively the same as 225 g.

Every butane guide gives you one number. In practice a cartridge does not have one runtime — it has a range, and the flame knob decides where you land in it. This guide breaks runtime down by flame setting, works out what an hour of cooking actually costs you, and shows the habits that move you from the bad end of the range to the good end.

Runtime by flame setting (ZORACook 225 g can)

That is a two-to-threefold difference from the same can, decided entirely by how you cook. If your cartridges seem to disappear quickly, the flame setting is almost always the reason before anything else.

Runtime by can size: 190 g, 220 g, 225 g, 227 g (8 oz) and 250 g

Flame setting decides most of your runtime, but the second variable is simply how much gas is in the can. Butane cans are not all the same size, and the number that matters is the net fill — the weight of the fuel, not the weight of the can plus the fuel.

At the same flame setting on the same burner, runtime scales with net fill. Working from the ZORACook can's measured 2 – 2.5 hours on a medium flame, that gives:

227 g and 8 oz are the same can. So are 250 g and 8.8 oz. If you have been comparing an Indian can against an imported one, convert first — the difference between 220 g and 227 g is about seven grams, which is under four minutes of cooking.

Watch the printed weight. Some cans print the gross weight, which includes the steel. A can advertised at "300 g" may hold only 190 g of fuel. The can safety check guide shows where the net fill is printed and how to spot a short fill.

A 230 g isobutane canister is not the same thing and will not fit. Isobutane canisters are a different fuel in a threaded EN417 screw-on canister — a squat cylinder with a Lindal valve on top. That is not what either ZORACook stove takes. The full-size Portable Gas Stove takes a long cassette can that presses into a fuel slot in the side until it locks; on the Mini Camping Stove the same cassette can screws horizontally into a threaded port on the side of the stove body. Neither accepts an EN417 canister — the valve and the fitting are different. Isobutane holds its pressure better in the cold, which is why trekkers use it at altitude, but it is not what a cassette stove runs on. The cassette vs screw-on guide explains which one your stove takes, and butane vs propane vs LPG covers when butane is the wrong fuel.

What about 100 g and 450 g canisters?

Search for butane runtimes and you will find plenty of pages quoting 100 g and 450 g canisters. Those figures are real, but they are not about the can in your hand. 100 g, 230 g and 450 g are the three standard sizes of the threaded EN417 canister — the squat, round backpacking canister with a Lindal valve on top, usually filled with an isobutane/propane blend rather than plain butane. They are the sizes British, American and European gear sites write about, because that is the format sold there.

None of those three sizes fits a cassette stove, and that includes both ZORACook stoves. It is not a question of a tight fit or the right adapter: the valve, the thread and the way the burner meets the fuel are a different standard end to end. Ordering one because a runtime chart looked attractive is the most expensive mistake in this category — you end up holding fuel you cannot use and cannot put back on the shelf.

Why we do not print a runtime for them. Runtime scales with net fill only while the burner stays the same, and these canisters run on a completely different burner with a different gas output. We cannot test one on a ZORACook stove, because it will not attach to a ZORACook stove — so any hour figure we printed here would be copied from somebody else rather than measured. What we can give you is the fuel arithmetic, which is only weight: a 100 g canister holds under half the fuel of a 225 g cassette can, and a 450 g canister holds roughly double it. Whatever your burner does with 225 g, the small canister gives you well under half of that and the large one about twice.

What an Indian buyer should check instead. Ignore size charts written for a different fitting and look at three things on the can you can actually buy here: the net fill in grams (220–225 g is the Indian standard, and cheap cans quietly drop to 180–190 g), the CRV safety valve, and the notched collar that marks it as a cassette can. Those three decide your runtime and your safety far more than any imported canister-size table. And if you need more cooking time, the answer in this format is more cans rather than a bigger can — the cassette can does not come in a 450 g version.

What an hour of cooking actually costs

Because runtime swings so widely, cost per hour is the honest way to compare. Using ZORACook's current fuel prices:

Two things fall out of this. First, cooking habits save you more than bulk buying does — dropping from a full flame to a simmer roughly halves your cost per hour, which is a bigger gain than any multipack discount. Second, the multipacks are still worth it if you cook on butane regularly, because the per-can price keeps falling all the way to twelve. The full ladder is in our butane price guide.

How to land at the good end of the range

• Use a lid. The single biggest change. Boiling with a lid on cuts the time the burner runs, not just the flame size.
• Match the flame to the pot base. Flame licking up the sides of the vessel is fuel heating the air, not your food.
• Shield the burner from wind. Outdoors, a breeze can add half again to your cooking time. See why wind empties a can faster and how to block it without a windshield.
• Turn it off between dishes. Idling between prep steps is invisible fuel loss — you never see it burn, but the can empties.
• Do not run it cold. Butane loses pressure in cold weather, so the stove works harder for the same heat. See our guide on butane stoves below 5°C.

Which cartridge fits your stove

The ZORACook Portable Gas Stove (₹1,099) takes standard cassette-style butane cartridges, aligned with the fuel slot and pressed in until they lock. The compact Mini Camping Stove (₹350) runs on exactly the same can, screwed horizontally into a threaded port on the side of the stove body. Our butane cartridge (₹199) fuels both, plus ZORACook's butane torches. Compare models in the portable stoves collection, or buy fuel from the butane gas cylinders collection.

Safety note

Use butane stoves only in well-ventilated spaces, never in a small sealed room. Keep cartridges away from heat and direct sun, and let the stove cool fully before changing one. Butane is flammable — store and handle it with care, and keep it away from children.

Frequently Asked Questions

How long does a butane cartridge last on high heat?
Roughly 1 to 1.5 hours of continuous use on a full flame for a standard ~220 g cartridge — about 2 to 3 meals.

How long does a butane cartridge last on low heat?
About 2.5 to 3+ hours on a low simmer, roughly double the high-flame runtime, because a smaller flame burns less fuel per minute.

What does an hour of butane cooking cost in India?
At ₹199 a can, roughly ₹159 per hour on a full flame and about ₹73 per hour on a low simmer. Buying a pack of 12 brings that down to about ₹107 and ₹48 respectively.

Does cooking style or bulk buying save more?
Cooking style. Moving from a full flame to a simmer roughly halves your cost per hour, which is a larger saving than the per-can discount on any multipack.

How long does a 220 g butane can last?
About 2 to 2.4 hours on a medium flame and 1 to 1.5 hours on a full flame. 220 g is the Indian standard fill; the ZORACook can holds 225 g, which is roughly six extra minutes of cooking.

How long does an 8 oz (227 g) butane canister last?
8 oz is 227 g, so about 2 to 2.5 hours on a medium flame and 1 to 1.5 hours on a full flame — effectively the same as a 225 g can. The seven-gram difference is under four minutes of cooking.

How long does a 250 g butane can last?
Roughly 2.2 to 2.8 hours on a medium flame and 1.1 to 1.7 hours on a full flame. 250 g is sold abroad as 8.8 oz. ZORACook does not sell a 250 g can — ours is 225 g.

Will a 230 g isobutane canister fit my cassette stove?
No. Isobutane comes in a threaded EN417 canister with a Lindal valve, which is a different fitting entirely. A ZORACook stove takes a long cassette butane can — pressed into the fuel slot on the full-size stove, or screwed horizontally into the side port on the Mini Camping Stove. Isobutane keeps its pressure better in the cold, but neither stove will accept the canister it comes in.

Do 100 g and 450 g butane canisters fit an Indian cassette stove?
No. 100 g, 230 g and 450 g are the standard sizes of the threaded EN417 screw-thread canister used by imported backpacking burners. That is a different fitting from the cassette can an Indian portable stove takes, so none of those sizes will attach to a ZORACook stove, with or without an adapter.

How long does a 100 g or 450 g butane canister last?
We do not publish a figure, because those canisters do not fit a ZORACook stove and we cannot measure them on our own burner. The fuel arithmetic is simple though: a 100 g canister holds under half the fuel of a 225 g cassette can, and a 450 g canister holds roughly double. The actual runtime depends on the burner they are used with, which is not one of ours.

How do I pay for ZORACook butane cartridges?
