Jetboil just launched their new and improved Jetboil Flash 1.0L and 1.8L cook systems for backpacking. And they certainly got a few welcome upgrades. Considering getting one? We’ll highlight what’s new with the recently released Jetboil Flash cooking system and who it’s for. Hint: backpackers–but not all backpackers.
What’s New with the Jetboil Flash
There’s plenty that’s new with the new Flash lineup. And we’re fans of all of it.
- New Sizes: Choose from 1.0L and 1.8L (we tested the 1.8).
- New Igniter: There’s now an easy automatic igniter on the Jetboil Flash! Igniters exist on several older models, but the new one on the Flash line is burlier, easier to use, and less likely to fail thanks to being encased in ceramic (igniters are usually the first thing to fail).
- New Handles: The 1.8L got a handle upgrade. While the smaller version is still just a webbing handle, the larger has more robust, silicone-sheathed folding handles to boost usability.
- Heat Indicators: Not all older models had heat indicators built into the insulated wrap that goes around the pot, but all new Flash models do. The flames turn from black to orange when water reaches boiling.
- Easy-Grab Stove: The burner base also got an upgrade. A bright orange textured grip zone makes it easier to connect the cookpot, adjust the flame, or attach a fuel canister.
- Available in a Java Option: Looking for an all-in-one boiling and coffee-making solution? Opt for the Flash Java, which comes with a removable and packable French-press style filter designed specifically for the Jetboil (you can also buy one separately).
- Compatibility: Yes, you CAN use a pan with the Jetboil Flash. It is compatible with a wide range of accessories, including the Grande Silicone Coffee Press. And if you use the stable and sturdy new Pot Support 2.0, the Summit Skillet and 1.5L Ceramic Cook Pot.
- New Windscreen Accessory: Boil more efficiently in breezy conditions with the new windscreen, which connects easily to any of the new Flash sizes and block the wind without overheating the burner.
What Stayed the Same
Of course, there’s plenty that Jetboil fans will still recognize.
- An easy-to-remove lid that offers pouring and straining functionalities.
- A FluxRing for fast and even heat distribution.
- Fast boiling: Heat up a liter of water in under 4 minutes on average (that’s a bit faster than the most comparable model, the Sumo).
- A bottom cover that doubles as a measuring cup or bowl, now with easier-to-read measurements.
- Packable functionality: Everything nestles into the cookpot or the bottom cover, including a gas canister, windscreen, burner, matches, and pot stand.
- The Jetboil Flash still uses isobutane fuel canisters and a 230g canister (the large ones) should last up to 90 minutes or 24 boil cycles when boiling 1L at a time (in ideal conditions).
- Simmer Functionality: Yes, the Jetboil Flash technically has a bit of heat regulation built into the knob, but simmering functionality is still limited. The flash still excels at boiling water over sautéing.
How it Functions
Naturally, we took the new Jetboil Flash 1.8 on a test run alongside our older model and we have to say, we were impressed.
For starters, the cookpot was much easier to secure to the burner base AND remove again when boiling was complete. That’s thanks to the new wrap-around grip on the burner base (which also keeps your fingers from singeing), but we also found the locking action smoother and more usable than older models.
Next, we much preferred the silicone folding handles on the larger version to the smaller webbing loop on older and smaller options. The webbing does help reduce weight, though, so if that’s your main concern, we certainly didn’t find the webbing handle a dealbreaker.
Boiling was as fast as expected, too. We tested the speed with just 12 oz of water and the new Flash made quick work of it, reaching boiling in just two minutes with a mostly full fuel canister. The older model we have took two and a half minutes. You can boil up to 1.25L at a time in the Jetboil Flash 1.8.
Speaking of boiling, we love to see the thermal indicator on the cockpit cozy that changes color when water reaches boiling. Older, smaller models didn’t have that feature so we had to constantly remove the lid to check if water was hot enough yet. Not so with all the new Flash models; they all have that handy feature.
The measuring cup was easier to use, too. Instead of being plain black like older versions, it’s semi-transparent. That makes the measurement lines easier to read, but because it’s also made out of a higher quality material, you can use it as a bowl or cup, too. We accidentally threw away the bottom cover from our first model because it looked so cheap and single-purpose we never imagined we were supposed to keep it. (We dug it out of the trash a day later when we bothered to read the instructions…)
Jetboil Sustainability
The brand isn’t the most standout in the outdoor industry when it comes to sustainability, but they are passionate about the outdoors, including in Maine where the brand is based. They currently host trail cleanups in partnership with the National Wildlife Federation and Clean Earth Challenge.
Jetboil also offers a 1-year warranty against manufacturing defects in the product. If something goes wrong in that time, they’ll fix your stove or replace it.
Who the Jetboil Flash Cooking System is For
While the new Flash is impressive and functions well, boils fast, and nests well with other cooking necessities, it’s not for everyone. What are the cons of the Jetboil?
For starters, it’s heavy. The 1.8 weighs 16 oz while the 1.0 weighs 13.1 oz (weights don’t include the recommended fuel stabilizer, which comes with the stove). Those weights certainly aren’t a dealbreaker for many backpackers, but ultralight backpackers will likely balk. I, personally, find Jetboil systems too heavy since I aim to keep my pack well under a 10-pound base weight. Instead, I choose an ultralight stove and ultralight pot.
It’s also important to note that as-is, the Flash cooking system is almost exclusively for boiling water in order to rehydrate freeze-dried backpacking meals, make tea or coffee, etc. If you prefer to cook actual ingredients on a stove like you would at home, you’ll have to purchase additional accessories like compatible pans or pots plus an adapter.
Likewise, the Flash system is designed to serve just two to four people, even the 1.8 size. Naturally, if you have more in your group, it’s still functional, some folks might just have to wait their turn for hot water as you boil in shifts.
It’s not a budget item at $165, but it’s definitely still comparable to (and sometimes cheaper than) similar high-performing and reliable cooking systems like the MSR Pocket Rocket Deluxe and MSR Windburner. So if you’re set on a fast-boiling cook system, the price of the Flash is actually pretty good.
Bottom Line: The New Jetboil Flash Stove
The new Jetboil cooking system certainly comes with plenty of upgrades, including burlier handles, a more reliable and easier-to-use igniter, and more functionality. All while maintaining the efficiency and simplicity the brand is known for.
Sure, it’s heavier than other options, but is the Jetboil Flash good at what it does? You betcha. In fact, for those more concerned with ease-of-use, fuel efficiency, and fast boiling than weight or size, the new Jetboil Flash is an excellent choice.
