How fast does the Jetboil Flash boil water?

Jetboil rates it at about 100 seconds for a boil, the fastest in the Flash line. Real times vary with wind, altitude and water temperature.

Can the Jetboil Flash simmer or cook food?

It is built mainly for boiling. The burner runs hot and is hard to dial down, so it suits coffee, soup and dehydrated meals better than skillet cooking.

What comes in the box?

The Flash includes the burner with pushbutton igniter, the 1-liter FluxRing cup with cozy and lid, and the bottom measuring cup. Accessories such as the coffee press and pot support are sold separately.

Does it work with standard canisters?

It runs on standard isobutane-propane backpacking canisters. The burner and cup nest together for packing.

How many people is it good for?

The 1-liter cup suits one or two people boiling water for drinks or dehydrated meals. Larger groups need a bigger pot or a second stove.

Is it worth it over a basic canister stove?

If you mainly boil water and want speed and an all-in-one setup, the Flash is a strong pick. A bare stove and separate pot is lighter and cheaper but slower and less convenient.
