I own quite a few of thee types of miniature gas canister stoves. And this would have to be my second favorite of all. It has some wind resistance from being blown out, which is nice, and the flame egress surface faces outwards to cover wider pots. It is also well suited for small pots and any cup designed for this purpose.
The heat output is also very high. And it also fits in most cups designed to hold a 100 gram gas canister.
Having said all that, it would really benefit from a wind screen/heat reflector.
There is one from Optimus that fits this well.
Currently, there is a wind screen being sold specifically for this type of vertically stacked stove, the Optimus wind screen. I don’t know yet if the pot stand tines are small enough to work with that wind screen, but if it does fit, and the setup works well, this may quikly become my new favorite. That would be impresive, because my favorit is pretty phenomenally awesome too.
Excerpt from Gear Junkie (author: shaun):
Having some trial and error experience with Jetboil, I can point out a few things about the fuel, and a few things that have worked for me. First, NOT all canister fuel is created equal. Here are a few for comparison, each with the relative temp values of each fuel – canister fuels are generally a mixture, and they are different ratios.
– Brunton/Kovea: 0% n-butane, 70% isobutane, 30% propane
– Coleman: 60% n-butane, 0% isobutane, 40% propane
– Primus: 70% n-butane, 10% isobutane, 20% propane
– Peak1: 70% n-butane, 0% isobutane, 30% propane
– MSR IsoPro: 0% n-butane, 80% isobutane, 20% propane
– JetPower: 0% n-butane, 80% isobutane, 20% propane
– Snow Peak: 0% n-butane, 65% isobutane, 35% propane
This is important since all fuels vaporize at different temps. Without some fuel left in the canister that is vaporized – it will leave no pressure to feed fuel to the stove. n-Butane vaporizes at 31°F. Isobutane vaporizes at 11°F. Propane vaporizes at -43°F. Essentially what that means is that n-Butane will not vaporize below 31°F, while the other mixtures do and leave useless liquid n-butane in the canister. At 11°F the same phenomenon happens with Isobutane.
So.. A low (or no) n-Butane mixture, and higher propane mixture are more suitable for colder temps.
