A water-boiling speed demon that will feed up to five and heat consistently in sub-freezing temperatures.
Jetboil's new Joule Group Cooking System is the company's largest backpacking stove to date, and its inverted canister design with a fuel regulator provides consistent heat in sub-freezing temperatures. Equipped with a voluminous 2.5-liter cooking vessel and powered by a 10,000 BTU burner, it'll boil soup or water for you and two to four of your friends or family members in less than three minutes (2 minutes and 40 seconds to be exact) when you're spending the night high up on a snowy mountain. The boiling time is almost half of Jetboil's other group cooking system unit (the Sumo), and the burner can be adjusted to simmer liquids as well bring them to a boil. The stove's smart design essentially turns the cooking vessel and burner into one integrated unit; Jetboil's patented FluxRing unites the two pieces, provides a built-in wind barrier, and efficiently draws hot air from the burner to the cooking vessel to enable its very rapid boiling rate. This integrated design, along with a beefier burner unit, also provides excellent stability.
The burner and fuel canister pack into the cooking vessel, and the locking handle on the cooking vessel folds down for a compact transporting size. Considering the stove's ability to feed up to five people, its 6.5x8-inch pack size is relatively compact. Once you've reached your stopping point for the day, stove set-up is a breeze, and doesn't require the special priming steps of much fussier liquid/multi-fuel systems. With one quick push of the Piezo igniter button, light the Joule, and get to work on your gourmet stew amidst stunning natural scenery that would put any four-star restaurant to shame.

- Q & A
Excellent portable stove unit. Super efficient boil time for those that need to make coffee and a few dehydrated meals while exploring off the beaten path. The piezo electric starter is a nice convenience to get it going quickly.
Holy crap this is a snow melting machine
- Familiarity: I've used it once or twice and have initial impressions
Used this the other day at 11,700' in about 10-20 F temperatures. It started right up, but took a few minutes to properly warm up. I recommend leaving the fuel flow rate to low until the thing gets warmed up. Once the stove was purring we brewed up 4L of water in under 30 minutes. We actually were having a tough time keeping the thing full of snow! Once full of snow it melted and warmed it faster than we could get the pot off to brew a second batch. A 4L pot for this sucker would be amazing for expeditions.
Packs great and performs even better.
For anyone that is asking the Joule system is kind of on its own when it comes to Jetboil compatibility. It wont be compatible with any of the other stove/cups. The sumo, flash, minimo, zip all use the same burner and attachment so they are all interchangable
Thanks for the info Michael, this is super helpful.
