Description

Pack MSR's compact, easy-to-use Reactor Stove system, and experience a new world of camp stove efficiency.

The MSR Reactor Stove seamlessly integrates a radiant burner, a heat exchanger, and a high-efficiency pot to provide you with a windproof, crazily fuel-efficient stove system for all conditions. So efficient is the Reactor Stove that it boils one liter of water in under three minutes so you can enjoy a quick, hot cup of tea in the morning before packing up for the ascent.
  • MSR's heat exchanger encloses the radiant burner, providing super-efficient fuel burn
  • Internal regulator puts out a consistent flame throughout the life of the canister and combats gusty winds and cold
  • Integrated stove-and-pot system increases fuel efficiency, nests together for convenience, and makes the system easy to set up
  • Package includes: Reactor stove, 1.7L hard anodized aluminum pot, handle, and BPA-free lid
  • Note: fuel canister sold separately

If you're heading out for some winter camping and need to melt snow. This is the one and only stove you need. Melts snow faster than anything I've seen. It uses a bit more fuel than others, but when you can be done melting snow 15 minutes faster than anyone (or anything) else, it's well worth it. Simmers pretty well and is fairly light.

It all stacks together neatly, which is cool, but the main thing is how amazingly fast it boils water or melts snow. It's incredible. MSR also makes a separate piezo igniter that's pretty neat.
I usually figure 1 large fuel canister for 2 people for 2 days.
The downsides are that fuel is less flexible than other stoves such as my msr dragonfly which I've run on various gasoline in foreign countries.. You have to have the canisters. But this stove is way better for backpacking in the cold.
If its very cold though you'll need to keep a canister in your jacket/sleeping bag for it to flow correctly. My last "gripe" is that there's no way to recycle the spent canisters. It'd be great if MSR had collections at various retail stores for the used canisters.
Overall the best stove I've seen for everything except places where you can't buy or carry enough fuel.

Great system

Awesome. You hear about people who hate any stove that uses these fuel canisters.. For one or two people this stove pot system rocks. I have been looking at getting the larger pot sold separately. I just feel that once you start getting into needing a larger pot you should move into a fuel bottle stove system and spread the load amongst those in the party.

Pretty cool stove! Hard to light in high wind but once it catches its definitely not going out even if you spill an entire pot of water on it. Obviously it boils fast. It even can be held if you are using it somewhere not recommended like in the tent. I do wish the pot would attach to prevent the aforementioned spilling but once that happens you learn quick to hold on tight and it hasn't been a problem since. The included pot is perfect for two people and will work for three if you dont have to melt much water. Three people in the winter might want a bigger pot. I like being able to store everything (including fuel) in the pot. It packs nicely into the bag and protects the stove well.

Used this up to 21000 ft and had no issues, boils well, heats evenly, great size for two people. Would love the pot to lock on, best set up for winter camping

This is great. Essentially windproof once lit. Works great in all temps and most elevations. Super fast and you can boil enough water for two freeze dried meals in 3 minutes or less. Only wish the pot attached to the stove to make it more secure. Other than that, this is a great stove for heating water.

I have an older Coleman lp stove for car...

I have an older Coleman lp stove for car camping but want something that is lightweight and solid construction where I can boil water, make water based food, and use for general food making. In talking with others msr makes the best lightweight stoves but don't know which is the best and most versatile. Any recommendations? My use is car camping or short hikes to camping areas

You could get away with much less stove - a pocket rocket or an older version of a liquid gas stove. This stove is the best of the best - you will enjoy it and it will last a long time. Check out a jetboil as well - a little lighter and works very well but not as well in the cold. Canister stoves in general are somewhat sensitive to the cold.

For a wide use of needs (car camping, actual cooking, short backpacking, etc.) it's tough to beat the MSR Windpro II. It's a bit more expensive than some stoves, but cheaper than the Reactor. And, it has a huge range of adjustability, can be used with a windscreen and allows you to invert the canister to feed it the fuel in a liquid form if the temps get too low.

I have the Reactor and the Windpro. While the Reactor rocks for super-fast water boiling in a number of conditions, I think the WindPro is a more solid, all-around choice.

Light weight, easy to light, easy to store, it's everything you need in one package. My only issue has been controlling the heat. On low I lose flame. Otherwise it boils water fast and doesn't use a ton of fuel.

high altitude, no regrets!

fast eating means HAPPY times! there's not much else to say oh the heat sink in this is so wonderful... all in itself the item is going to left you wondering why is it that I used something else ALL THIS TIME!!!

I spend most of my time in the Ecuadorian Andes (cooking at 10,000-15,000 feet) and this is my "go to" stove. I've also used it on weeklong trips in Peru's Cordillera Blanca with similar high altitudes. Pros: fast setup, fast cool, the boil champ! Cons: the boil champ simmers poorly and won't accept other pots or pans. If you want something hot in a hurry at high altitude, look no further. While I still use my MSR Whisperlite International at lower altitudes or if I have lots of time to cook, I prefer to sleep than tinker with it at high altitude.

Will boil water faster than you can put a chuck of chocolate in your mug, it will shock you! Well built, high quality. Keep in mind it is not for cooking just boiling I only put water in it. Has never let me down there are other brands that seem similar but don't be fooled they do not compare. Get this thing I recommend also getting a titanium spork to go with it. Ps it can hold that larger fuel canister if you do a little Tetris.

I love this stove, It boils wicked fast. However it is a bit heavy and bulky. But for not being a white gas stove it works great in canister stove conditions.

This thing is an oven. MSR's graphs that are provided on their box are certainly accurate as well. At 7500 feet this thing had no problem with melting snow and probably enjoyed the chance to show off. People like to worry about stoves that run off of isobutane/propane because performance decreases with the amount of fuel you use. In the case of the Reactor, it only requires 1.8psi in the can to be burning at full bore. Most cans are filled to 6psi. Jet Boil in comparison requires 3psi. Therefore this product takes an even farther leap in design than Jet Boil in terms of performance/function.

This stove works off of radiant heat and not convective so more of the energy goes to heating the water and less is diffused into the air by convection. It works in really high winds even. No need to use a screen to trap in heat...

This thing rocks.

One trick I want to share with people is that another way to get more out of your canisters is to make a neoprene 'sock' to envelope the bottom and sides of the cannister. After using the fuel and during use, put a hand warmer under the can and then slip on the sock. This helps at altitude and in colder temps.

Only two complaints. This is a combination setup where this stove and the pot are made for eachother. You cannot use another pot with this stove. Secondly, one thing that the Jet Boil has on the Reactor is the locking mechanism to keep the pot attached to the stove. From what I hear, this was intentionally left out by MSR for matters of safety.

Buy this thing! It boils 2 cups in about 1min and 25sec and 4 cups in 2min and 30-40sec. It is pretty huge, but hey, it's smaller than a Saturn V rocket engine lol. If you nest it with an 8 oz fuel can, don't count on putting much else in there with it. Be careful how you pack it. The folding handle will scar stuff(my platypus) in your pack, if it constantly rubs it. I ended up wraping it in my sham-wow. It is hard to light in wind. Tip: to get it primed(turn red) hold your lighter over it and then move your hand quickly because the excess gas lights first(you can't see it!!). You will see a slight vapor if it lit. Then IMMEDIATELY set the pot on the burner. Once the burner is covered by the pot it will prime on its own.
