If youre looking for a stove that offers delicate simmering performance so you can cook your meal just right and serve it up on the picnic table against a beautiful backdrop of a lake in the summertime youve come to the wrong stove. The MSR Reactor is an all-out, maximum-power water boiling and snow melting machine. For alpinists who want to whip up something hot and fast in inhospitable environments, the Reactor is the way to go. The Reactor uses MSRs Auto-Start ignition, which fires up the stove with the push of a button, and the stove systems burner utilizes both convective and radiant heat for greater heat output. The integrated heat exchanger is fused right into the 1.7-liter pot and completely encloses and locks in the radiant burner to provide total wind protection. An internal regulator equalizes fuel pressure for consistent flame output in all temperatures, meaning youll be boiling that last liter of water nearly as fast as the first. The Reactor boils its first liter of water off a full canister in less than three minutes and its last liter from the end of a canister at three and a half minutes, a marginal performance difference. And since it burns 22 liters of water per 8-ounce canister, youll be carrying less fuel overall.
