Marko Posted March 24, 2006 Share Posted March 24, 2006 Anyone use these in cold weather and have an opinion on them? Thanks Quote Link to comment Share on other sites More sharing options...

John Frieh Posted March 24, 2006 Share Posted March 24, 2006 Seen the new pot? 2.5 L capacity. I haven't used them in cold weather... nothing below 0 F but them seem to do well at least above 0 F. They are much easier to light/ignite if you use the jetboil brand canister. If you can wait a month Marcus took one to the Ruth Gorge... he should have an opinion when he gets back.

Ade Posted March 24, 2006 Share Posted March 24, 2006 (edited) Humm... Yes not exactly something for melting a lot of snow in. Pity. If they made the same base but for a larger pot it might be really good. Doh... So it looks like they do. 1.5l is still a bit on the small side for melting dry snow. I usually use a 2l just to get more snow in it. Edited March 24, 2006 by Ade Quote Link to comment Share on other sites More sharing options...

John Frieh Posted March 24, 2006 Share Posted March 24, 2006 My understanding is the new pot fits on the old base. Quote Link to comment Share on other sites More sharing options...
tomtom Posted March 24, 2006 Share Posted March 24, 2006 If you preheat the pot by filling it with hot water, it will melt snow faster. Quote Link to comment Share on other sites More sharing options...
Ade Posted March 24, 2006 Share Posted March 24, 2006 If you preheat the pot by filling it with hot water, it will melt snow faster. If I had hot water I wouldn't need a stove now would I? More interestingly if you compare the stats for an MSR Pocket Rocket and Jetboil they don't seem to be much different. Quote Link to comment Share on other sites More sharing options...
John Frieh Posted March 24, 2006 Share Posted March 24, 2006 tomtom is making a reference to my thermos recommendation thread. It's the new neutrino joke... I think the selling point w/ the jetboil is weight... you want efficiency go XKG Quote Link to comment Share on other sites More sharing options...
cj001f Posted March 24, 2006 Share Posted March 24, 2006 How's that much different than a pocket rocket, aside from the pot cozy? Quote Link to comment Share on other sites More sharing options...
John Frieh Posted March 24, 2006 Share Posted March 24, 2006 Built in heat exchanger. Quote Link to comment Share on other sites More sharing options...
cj001f Posted March 24, 2006 Share Posted March 24, 2006 Built in heat exchanger. That'll pack really well, and last Quote Link to comment Share on other sites More sharing options...
Ade Posted March 25, 2006 Share Posted March 25, 2006 I think the selling point w/ the jetboil is weight... you want efficiency go XKG But according to the numbers on MSRs site it's no lighter and doesn't boil more water or any faster. A Pocket Rocket + pan is about 400g, the jetboil comes in at over 500g. The only thing is seems to be better at is it'll boil more water per cylinder so I guess for long trips you can save weight. Can't say I'm entirely convinced. Ade Quote Link to comment Share on other sites More sharing options...

foraker Posted March 25, 2006 Share Posted March 25, 2006 You want to save weight, try losing 5 pounds instead of worrying about 100g. Quote Link to comment Share on other sites More sharing options...
Ade Posted March 25, 2006 Share Posted March 25, 2006 You want to save weight, try losing 5 pounds instead of worrying about 100g. No shit. Really? I'm not trying to save weight. But their marketing department is telling me their stove is better and lighter than the competition and I just don't see it. Quote Link to comment Share on other sites More sharing options...
alexbaker Posted March 25, 2006 Share Posted March 25, 2006 I used one in sub-freezing last weekend. About 20 deg maybe. Although not real cold, it performed awesomely. The pot that came with mine was just a tad short for filling a Nalgene. Other than that, the snow was dry but I got water remarkably fast. I recommend buying an extra long spoon for this one. all in all, i was very impressed. Alex Quote Link to comment Share on other sites More sharing options...
Ade Posted March 26, 2006 Share Posted March 26, 2006 So the big difference... Seeing as onbody else has pointed it out is that the MSR figures are for water boiled per 8oz fuel cannister and the JetBoil number is for a 3.5oz cannister so theirs is over twice as efficent.

marylou Posted March 26, 2006 Share Posted March 26, 2006 It's difficult to compare boil times between the Jetboil and other stoves as well. The standard lab boil test involves boiling a liter of water and the J'boil holds a half liter. I did the standard lab test with the J'boil and a number of other stoves, adjusting the water amount to a half liter in all stoves, and the J'boil was not the fastest, but it was competitive. I did not replicate the test in the field, nor did I do the fuel efficiency tests. Quote Link to comment Share on other sites More sharing options...
Chad_A Posted March 26, 2006 Share Posted March 26, 2006 Granted, it wasn't that cold when we were camped below Eldorado, but it seemed that the insulated "pot" that came with my pal's heated up really fast, and the insulator kept the fluid warm for a really long time. I guess if you really believed in it, you could have your partner buy another insulated "pot" for it to carry themselves, and you could heat up individual goods. One thing that is nice is that those little canisters fit really well inside it's own rig, and I think two of them will fit.

sean_beanntan Posted March 27, 2006 Share Posted March 27, 2006 Anyone read the label on the Jetboil that says "do not use to melt snow".hmm Quote Link to comment Share on other sites More sharing options...
JackY Posted March 27, 2006 Share Posted March 27, 2006 I think isobutane boils at about 18F. One way to solve this problem below that temp. is to submerge the canaster in liquid water. Quote Link to comment Share on other sites More sharing options...
Ade Posted March 29, 2006 Share Posted March 29, 2006 So I'm set. Just don't melt snow in it and have a bunch of hot water handly to make sure the fuel is liquid. And all for the same price as an XGK. Quote Link to comment Share on other sites More sharing options...
JackY Posted March 29, 2006 Share Posted March 29, 2006 I melt snow in mine. And I said liquid water, not hot water. Quote Link to comment Share on other sites More sharing options...
Marko Posted March 30, 2006 Author Share Posted March 30, 2006 So I went and bought one and used it up in the hills the other night (~20°F). Kinda cool all unitized and all. It'll be a great hanging stove. Seemed similar in cool weather performance to the old Pocket Rocket. Pot's OK if you're not in a hurry melting snow, but sucks if you're used to a 2 liter pot. Then I took it home and did a battle of the stoves boiling ice blocks. Attached are the results in an Excel spreadsheet. Basically, in spite of the better efficiency of canister stoves, I'm taking the old tried and true Whisperlight up to Alaska again.
