The Jetboil Flash is, quite rightly, most famous for the incredible speed with which it brings water to the boil – stick 500ml in the pot, fire it up and in just over a minute and a half the stove will be wobbling with excitement, with steam billowing from the top. For this reason it’s a very popular choice for everyone from backpackers to mountaineers, for whom quickly getting hot water to rehydrate a and make a warm drink, often in challenging and uncomfortable circumstances, is a massive priority. But the Flash is more than just a superhero kettle.
It’s a masterpiece of small-item engineering and part of a family with a massive legacy. Jetboil stoves – like Gore-Tex , Therm-a-Rest , Camelbak and Leatherman – are one of an elite group of products that genuinely rocked the outdoor world when they were first released, and they have been revered and widely imitated ever since. So, is the Jetboil Flash one of the ? The answer to that is an emphatic yes, and I’ll fight anyone who says otherwise.
But in the meantime, let me try to convince you in a more civilized way. The reason the Jetboil can boil water so quickly is that there is next-to-no energy wastage. The design includes a FluxRing on the bespoke one-liter pot that comes included with the Flash cooking set, which is a conducting collar that concentrates almost all the heat produced by the genuinely jet-like burner directly upwards towards the contents of the pot, with very little escaping out of the sides.
