- How long does one canister last?
- A 16 oz propane cylinder boils about 8–10 liters of water — enough for 2–3 hot meals for a family of 4.
- Can I use a camp stove indoors?
- Only with serious ventilation (open window, crack the door) and never in a small sealed room. Propane produces CO when combusted incompletely.
- Are butane and propane interchangeable?
- No. They use different canister threads. Butane performs poorly below ~0°C (32°F), propane handles much lower temps.
