was given a tip for using the jetboil in winter, to put a gel handwarmer under the gas cartridge to keep it warm and presumably recharge another while boiling water ready for next time.
I was wondering if anyone has tried this and is it safe ?

Could do, but I just keep my canister in my sleeping bag which seems to work well enough.

Promise used to sell a gel pack specifically for this, so yes it's safe.

Used a Jetboil in Iceland with temps down to -15C and didn't have any trouble. Shouldn't really be a need for gel packs to be honest as long as you have the right gas. If it's that cold I'd rather use them for myself!

Just keep gas canisters off the ground and warm them up a little before using, and make sure to gradually add snow to melt it rather than just smashing the lot in. No trouble whatsoever*



*except trying to light the damn thing in the wind :(

In reply to wobl: Once it's going you can pour a spoonful of the hot water onto the canister before putting more snow/ice in and it'll launch back into life.

I find having a Trangia to gently warm the gas canister helps too


But seriously, off the ground helps a lot <in snow> and bare hands on the canister helps too, the heat from your hands is enough to help the fuel turn to vapour

off the ground helps a lot

I was told that the gel packs were used with a hanging kit in snow

In reply to wobl: makes sense that, at the end of the day its all about ambiant temp so even a fraction of a difference will make a difference
