This stove runs off butane instead of propane like many other camp stoves. The canisters are a bit smaller and should last at least an hour on full flame/heat. The nice thing about this stove is how easy it is to hook up the fuel. With this stove you don’t have to thread/twist the canister on. Just drop it in the slot and push down on a lever that locks it into place and pressurizes the system. Then just turn the knob past max till it clicks and the igniter sparks into the gas. It’s that easy and you’re cooking!
