The Jetboil Flash Personal Cooking System

JetBoil Flash

Per the collective request of several of you, I will begin reviewing some compact camping stoves. I think having one (or two or three) of these systems is an important component of being self-reliant. The first one, and the subject of this review, is the Jetboil Flash. The Jetboil has been around for years (since 2001), and is the gold standard in personal camp stoves. It is used by backpackers, climbers, preppers, special operations personnel, and just about everyone else who spends significant time away from the comforts of home.

The first Jetboil I ever encountered belonged to one of my teammates back in 2004 or 2005. This cooking system was a game-changer in my mind. I had done a good amount of backpacking in the 1990s when the “dual-fuel” and “multi-fuel” stoves were all the rage. These stoves worked on gasoline, white (Coleman) gas, kerosene (and sometimes diesel), which was cool because you could find a fill-up just about anywhere. But they were finicky, required a lengthy bottle-priming process, and could be hard to get lit. The Jetboil Flash doesn’t suffer any of these ills; pretty much anyone can use it and it’s easy. I finally purchased my first (and so far only) Jetboil about five years ago.

The Jetboil Flash: Benefits

The Jetboil Flash has some incredible benefits. The first is speed and user-friendliness. The Jetboil sets up extremely quickly. Simply open the self-contained cup, and remove the stove and fuel canister. Screw the canister onto the stove, and attach the cup to the stove. Open the fuel regulator and press the piezo ignition. You should have boiling water in under three minutes. Simple as that! The Jetboil also cools really quickly, allowing you to pack it up with little delay.

The speed in this system is due largely to its insane efficiency. unlike many stoves there is very little wasted energy. I also like the self-contained nature of the Jetboil Flash. It has everything you need built into a convenient unit. The Jetboil Flash is NOT the most compact unit on the market. The cup that comes with it holds all other components of the stove, but is big. It does feature a heat-proof sleeve with a built-in, color-changing “hot” indicator.

The Jetboil Flash’s temperature regulator is a simple wire dial. Opening it all the way will get water hot, FAST! Dialing it down a bit will lower the temperature, but how much exactly is debatable. This isn’t a suitable stove for something that requires a long, low simmer, like pinto beans. This stove is designed with a single purpose in mind: boil water, and do it in a hurry.

The Jetboil’s fuel regulator is simple to use and allows a wide range of temperature settings from “full-on boil” to “full-on simmer”. Author’s note: the setting designations are my own, and not those described in Jetboil literature.

Because the Jetboil is so popular, it is also amply supported with a wide array of accessories to suit every discerning camp cookie. My Jetboil Flash is stock, but if you want you can outfit yours to the nines. There are frying pans made specifically for the stove unit. If I were going to purchase one accessory for my Jetboil Flash it would be the FluxRing Fry Pan for the flexibilty of cooking things other than water. There are also French press units for you coffee connoisseurs. There is even a steel ring setup that allows you to use non-Jetboil pots and pans.

The Jetboil Flash: Drawbacks

Being a very specialized tool, the JetBoil Flash also has some drawbacks. The biggest of these, in my mind, is the fuel. The JetBoil runs on “Jetpower,” a proprietary propane/butane mix. You can also run it on competing canisters from Primus and Coleman. These canisters come in a variety of sizes which can be characterized as “big” and “small.” Although Jetboil advertises a mid-sized canister (which I’d really like to run across for several reasons) I’ve only found the 3.5-ounce and 16-ounce Jet Power units. The isobutane/propane fuels from Primus (called Power Gas), Coleman, and GSI (available at Dick’s Sporting Goods) come in a variety of other sizes, but again, these can generally be lumped into the aforementioned two categories.

The large (15 to 16-ounce) fuel canisters last substantially longer, cost proportionally less, and make a more stable platform for the stove. Unfortunately, they are too large to fit into the Jetboil’s cup.

The Jetboil’s proprietary fuel system isn’t a problem normally; one can usually find fuel from one of these brands, everywhere from REI and EMS to Walmart and Dick’s Sporting Goods. And even the small fuel cartridges last longer than you’d think if used somewhat sparingly. In hard times, though, suitable fuel might be hard to come by and if you don’t have fuel, this stove is pretty much worthless. Of course I have a few laid by, but these will eventually run out.

One other potential point of failure with the Jetboil is the igniter. Though I have not personally experienced this, the igniter is widely regarded as the part most likely to fail. You can still light the thing without the igniter (assuming you have a match) but it’s not easy. Spare ignition assemblies used to be sold but every site I’ve checked in the last month lists them as “temporarily unavailable.” I really wish I’d bought a few of these a couple of years ago.

The Bottom Line

The final drawback with the Jetboil flash is cost. New units run around $110. If you have the spare cash for it (or spend a ton of time outdoors), the Jetboil Flash is a ridiculously good stove. It isn’t without fault; it’s Achilles’ Heel is its propriety, waste-producing, factory-filled fuel canisters. However, it is efficient, fast, user-friendly, and completely self-contained.

The Jetboil Flash is one of the top-performers all-around is well-respected among those who spend a large amount of time outdoors. If you can afford one, and maybe a dozen large fuel cartridges, you will be pretty well prepared, and you certainly won’t be disappointed. I would recommend keeping a backup stove handy, though – I don’t like putting all my eggs in one basket. I’ll talk about some worthy backups and (more affordable) alternatives to the JetBoil in upcoming posts. Stay tuned!

  1. Cost is not bad for a good stove like this one, but as with guns I am an old-school camper. Precisely because it runs on multiple fuels I use one of those stoves. I have not had much trouble priming or starting mine.

    1. It is costly. I lived off mine for about six weeks two summers ago, and with that kind of use (2-3x/day) the time saved makes it totally worth it, without question.

  2. I’ll concur that it is more than I would like to spend, but it isn’t beyond what I would be willing to spend. Ideally, I would like to get something a little more affordable and possibly a bit more versatile right out of the box, though, so I will be looking forward to your other reviews.
    I don’t know if your meal at the Jones Creek Campground was good, but at least we know your beer was.

  3. Great story, Justin!

    I used a classic Coleman stove for years and years. I have many fond memories of remote campsite evenings with that stove. And it was relatively inexpensive – especially considering how many years of service it gave.

    Alas, it was fiddly. Like the carbureted motor vehicles we all had when I bought it, altitude wasn’t its friend. It was more sensitive to cold weather than I was, which was saying something. And although I took some sort of perverse comfort in knowing I could find fuel for it most anywhere, fact is I never once siphoned gasoline for it out of my motorcycle, or otherwise went scrounging.

    Like you, nowadays it’s the Jetboil for me. Faster, cleaner, easier, safer, and vastly more efficient. It’s an amazing stove. I wouldn’t go back on a bet!

  4. Whole lot more compact than a 1-gallon can (with a few holes in the side, .22-size), a half dozen charcoal briquettes, a tiny can of charcoal lighter (that you had to hope didn’t spill or evaporate), and a box of matches. Of course, with that rig, when you run out of charcoal, it was easy to find wood to burn–if it wasn’t raining. Still had to stay supplied with matches, or hope somebody in the group smoked; they usually had a Zippo.
    Makes me wish I still got out and did things where a compact stove would be useful. Maybe when the grandbaby gets a little older…..
    Looking forward to more articles along this line—-but don’t forget the revawvers, too. Ace

  5. Looking forward to your further reviews! Im particularly interested in the previously discussed (in past column) that runs on twigs, scraps, etc. I still have my Whisperlite International…but things have advanced much over the past 20 years. By the way…couldnt help but notice the Black Butte Porter in the background. Solid choice!!

  6. I’m really enjoying the occasional review of other types of outdoor gear on this site. I’ve used a Jetboil for many years, and they are insanely efficient. Most of my outdoor trips involve backpacking or bikepacking, and recently I’ve decided to opt for more lightweight alternatives, so my main stove for the backountry these days is either an MSR Pocket Rocket 2, or an Emberlit Ti stove, depending somewhat on the type of trip, anticipated weather, etc.

    The Jetboil still gets a fair bit of use though, and I particularly love it for road trips, where I can pull off somewhere and quickly have boiling water and a cup o’ joe on the tailgate before driving on.

    p.s. – you better guard your Black Butte porter if my wife is ever around, that’s her beer of choice. 😉
