Overview
Built around its own 1 liter cook cup, the Jetboil Flash 1.0L (model FLMS3) is a fast-boil backpacking stove with auto ignition, aimed at heating water for coffee, tea, and dehydrated meals rather than pan cooking.
Turning the knob about half a turn counterclockwise fires the burner without a match or lighter, and three locking points with visual indicators confirm the cup is seated securely on the burner before use. Everything, including a 100 g fuel canister sold separately, packs inside the 1 liter cup for storage.
- One-step auto ignition, no match needed
- Boils 16 oz of water in about 2 minutes
- Three-point locking pot-to-burner connection
- Packs into its own 1 liter cook cup
Who it's for
Backpackers and hikers who mainly need hot water fast, for coffee, tea, or dehydrated meals. Less suited to anyone who wants to simmer or cook ingredients in an open pan.
Pros and cons
- Boils 16 oz of water in about 2 minutes
- Auto ignition lights the burner without a match or lighter
- Packs into its own cup along with the fuel canister
- Bottom cup doubles as a measuring cup or bowl
- Fuel canister is sold separately
- Built around its own 1 liter cup rather than an open pan, so it favors boiling over cooking
Performance notes
The turn-and-click knob produces a cooking flame the way a home stove does, with no match needed, and the stainless steel burner locks to the cup at three points for a secure connection. The design boils 16 ounces of water in about 2 minutes, and the insulated cozy around the cup holds heat afterward.
