If you boil water for coffee, dehydrated meals, or one-pot dishes, get the JetBoil Flash. It has a two-minute boil time (for one liter) and features an insulating cookpot sleeve with a window that changes color when the water’s about to boil. Gimmicky? It would seem so, but our Colorado tester (who used it in temps down to 30°F) estimates that she was able to cook another weekend of meals on the fuel she saved. $100; 15 oz.; jetboil.com
With great fuel efficiency, quick boil times, and a small packed size, this stove is ideal for campers who need hot water fast, without the fuss.
