How long does a 230g gas canister last?

A 230g canister typically provides 40-70 minutes of burn time at full power, or 80-120 minutes at a simmer. This translates to roughly 15-25 boils of 0.5L water, or 7-12 days of basic 2-meal-a-day camping. Actual duration depends on stove efficiency, altitude, wind, and water temperature.

What affects stove burn rate?

Key factors: flame setting (simmer vs full power), wind exposure (can double consumption), temperature (cold reduces canister pressure), altitude (affects both pressure and boiling point), and stove design (integrated systems like Jetboil are much more efficient than open burners).

How do I make fuel last longer?

Use a windshield (can halve fuel consumption). Use a lid on your pot. Heat only the water you need. Use an integrated stove system. Simmer rather than boil. In cold weather, warm the canister in your jacket before use. Choose dehydrated meals that only need hot water, not long cooking times.

What is the burn rate of my stove?

Check your stove specifications. Typical rates: MSR PocketRocket ~3.5g/min, Jetboil Flash ~2.8g/min, Trangia alcohol stove ~2g/min, Esbit solid fuel ~1.2g/min. If not specified, use 3-4g/min for canister stoves and 2g/min for alcohol stoves as estimates.

How We Calculate This

Burn Time

Burn time = Fuel amount / (Burn rate x Flame setting multiplier)

Flame multipliers: Low (0.4x), Medium (0.65x), High (1.0x)

Usage Estimate

Average boil: 3-6 minutes. Average meals: 1.5 boils each. Days = Meals / 2 hot meals per day.
