Figured I’d share here since it’s probably useful to someone. I recently did some fuel consumption testing with a fairly common canister stove setup (MSR Pocket Rocket Deluxe + Toaks 750ml with stock lid), in preparation for a Wind River High Route trip.

I boiled fourteen 250ml batches of water (amount of water used in typical 1p dehydrated meal pouches and morning coffee), plus two 450ml batches of water (amount of water used in typical 2p dehydrated meal pouches). After these sixteen boils, I had enough fuel remaining to warm, but not boil, a 250ml batch of water. All the water came from a bowl of ice water that I added ice to and let sit until the ice stopped melting, to simulate a glacial meltwater source at 32f. I stopped each test once I reached a rolling boil.

TLDR - if you’re boiling glacial melt water (ie near freezing start temps), you can expect to get fourteen 250ml boils plus two 450ml boils out of a 100g MSR IsoPro fuel canister using this pot/stove setup in wind-free conditions.

Adjust your expectations accordingly if you are using warmer water sources, or if you’ll be frequently boiling water in windy conditions.
