I took a JetBoil Sol Ti on the JMT in August. I made two brews of tea and one hot meal per day, each of 500 mls. The tea was heated to 75c, and the meal water - Mountain House type or oatmeal- heated to boiling. I got 31 brews/meals out of one Snow Peak Giga Power 110gm canister, which, for me , was 9 days, so I only ever had to carry one small canister between resupply.
This stove is so fast, the tea took only 1.5 mins.
However, don't try heating food in the Jetboil, even gentle reheating of porridge for 30 secs burnt the pan base above the heat exchanger.
