Coleman Fyrestorm PCS – remote canister stove

I took the liberty of converting the units to their Imperial counterparts. It could certainly stand to reduce the weight – 486 grams is a bit over a pound.  Producing 7500 BTU (2200 W), and a boil time of over 6 minutes isn’t terribly impressive either, even in the stated 3 M/S wind (which is a bit over 6 MPH).

The gas canister it’s attached to, on the other hand, is intriguing.  It claims to work to -27C.  That’s about -16 Fahrenheit, which is darned impressive.  I wonder what the propane content is.

Yeah, WAY too heavy(~17oz) for the power. I will pass…

It looks to me like what you get when you let someone from marketing (instead of an engineer) do the design. Coleman USED to have a brilliant stove designer, but he seems to have retired. Some of their later designs have been almost grotesque.

Working at -27 C? Sure. you can do that with a standard 30% propane / 70 % isobutane mix. Nothing special about that. Several brands offer that (but maybe not in the USA).
Go up to 1,000 m and you can get down to -30 C. (-35 C at 3,000 m.)

But note: this is with a NEW canister. If you use the canister inverted ALL the time, you should be good to the end. But if you try to use the canister upright you will very quickly die. (OK, the canister will die.) There are 2 reasons for this: chilling down of the fuel in the short term and preferential loss of the propane in the long term.

But the marketing spin does not tell you that.
