MSR Reactor 1.0 L

MSR Reactor 1.0 L

After our previous stove failed in Iceland. We had to buy a new stove. We wanted to try a different brand then the Jetboil that we used before. Our main priority is to boil water really fast, cooking other meals is not necessary for us. Because we always eat freeze dried meals. During our search, we found the MSR Reactor 1.0L.

We like the design of the pot, the handle on the pot makes it easy to use. It pot does not attach to the stove when you are cooking. So you have to be careful when you are cooking. But we do not find it a disadvantage, we found the attached pot sometimes dangerous when it doesn’t want to come loose once the water was boiling. There is enough space in the pot to put the stove and 2 foldable spoons together in it. Or you can put a 100-gram gas can and the stove in the pot. When you flip the handle of the pot you can close and secure it for transport.

The stove looks very solid, a lot of metal parts compared with the Jetboil that we had before. That’s probably the reason why the reactor is a little bit heavier, it weighs 420 grams. The boil time of the burner is super fast. In about 4 to 5 minutes you got 1 litre of boiling water. We ignite the stove with a strike ignitor so that the sparks land directly on the metal foam. Once the stove burns correctly the foam becomes red and you can see the MSR logo.

We had once a malfunction while we were using it in Norway. We had a blue flame on top of the foam. I found some other people that had the same problem. It’s possible that was not enough air movement around the stove. But there is a solution when it happens while you’re in the backcountry. If there is a blue flame, you have to place a finger in front of the air intakes on either side of the control valve. This should act as a choke to reduce the air intake and richen the fuel mixture. But be careful doing this because the stove is warm around the top of the stove. But this solution should work. 🙂

Like I said before, it’s not possible to slowly cook some food with the stove. This stove simple does not simmer. If that is a problem for you, you should take another stove.


  • compact
  • solid build quality
  • fast boiling time
  • stormproof
  • simple to use
  • fuel efficient ( 20 litre per 225 gram canister )
  • pot does not attach to the stove ( saver when the water is boiling )


  • maybe a bit heavy
  • no simmer function
