A little experiment today. I timed the burn-off of a full small fuel canister.
Outside temp 53F
You're welcome 😉
@Philreedshikes Thanks for posting!
What kind of stove was it? It looks like a pocket rocket but I am curious. Perhaps a Soto? Any idea on how long that stove takes to boil water?
@REI-JohnJ the stove is an "Outsmart"
I did some stove comparison tests while getting ready for a JMT trip:
Goal – to find the best stove/pot/cup – AND FUEL CANISTER combination for a trip of at least 7 days, but not needing to exceed 7 days.
Best means lightest weight and enough fuel for at least 7 days. Seven days means boiling (for the test) 2cups of water up to a maximum of 4 times in a 24hr period, for an expected burn schedule of; 1-2 cups for breakfast meal, 2 cups for 2 coffees, 2 cups for dinner package re-hydration, 1 cup for possible evening herbal tea, plus 1 cup extra.
Burns means bringing 2 cups of water to a boil. Assumptions:
Note: while reviewing manufacturer data on various stoves and their boil times and fuel usage, the common test factor was the time to boil 1 liter of water, with the water at 68F or room temperature. I don’t think I’ve ever boiled more than 2 cups at a time and my “room” is the outdoors with the water (snowmelt) at least in the 40F range.
For my tests I used water stored outside with temperatures in the 40’s. Note:
For a weekend trip, the final best stove/fuel-can result is totally different because you may only need 4-8 burns.
Here are the tabular data, presented this way because the margins here are so narrow:

In my own tests with the Soto Windmaster fuel consumption to achieve a rolling two cup boil varied depending on how high I cranked up the burner. Using half-turn (180 degree increments) I found I could optimize my burner for minimum time to boil or minimal fuel consumption.
For raw speed I use settings that spill heat up the sides of my Toaks 600. This wastes is completely unacceptable for minimal fuel use. I recommend that each hiker experiment with their own configuration to learn how best to use it to meet your goals.
