MSR Reactor Stove System – Coffee In Less Than One Minute

The MSR Reactor Stove System is a great little personal cooking system designed for single person use while climbing, hiking, and camping, for cooking, boiling, and heating.

This can sometimes prove to be tricky unless of course, you have a small stove such as this one. Shopping for the right stove for outdoor activities can be overwhelming but it comes down to its reliability, durability, lightweight, and ease of use 

You need a unit that can perform in extreme outdoor weather conditions, and it should be durable despite being constantly moved around and exposed to the unpredictable outdoor environment.

Let me walk you through my post and give you insights into a product we have done much research on so you can get an idea of the benefits of the stove and if it may be able to help you with your cooking and boiling on your next adventure.


The Key Features

Fast boil time

What better place to start than looking at the core of the performance. When setting out to get that ideal stove, the duration of boil time is one of the most important considerations to look into.

After all, the last thing you want is a portable stove that takes forever to boil a cup of coffee when you are already behind schedule.

There’s some good news for you, this one offers quite unbeatable performance at this, with a tested and proven ability to boil half a liter of water in as less as 1.5 minutes, one cup full in less than a minute.

So if time is of the essence for you, then you can be sure you won’t be wasting any precious minutes waiting for a breakfast drink to boil.

An integrated compact system

Size and performance go hand in hand when it comes to these stoves. It should deliver at best, but without being too big to take up all the space in your backpack.

Measuring only 8 inches by 6 inches by 6 inches that’s one area this unit doesn’t disappoint at, it will fit very comfortably in your backpack

Thanks to the state-of-the-art design, this stove packs in quite the punch to take on your cooking needs on a stride despite being a small gizmo that you can carry with ease. 

It’s a little compact unit that’s super easy to transport, and it weighs only 1.09 pounds, so it won’t weigh you down.

Wonderful performance in windy conditions

If there’s one thing out there that gives these stoves a hard time as far as performance goes, then it has to be the wind.

Cooking with gusts of wind blowing all around you is not only frustratingly slow, but it also means the unit uses a lot of fuel than it would during less windy or calm conditions.

To ensure this never has to be a concern for you, this MSR stove is built with the necessity of cooking during windy weather in mind.

Thus, it features an unbeatable wind protection design, with the heat exchanger built to enclose the radiant burner head completely.

This construction ensures that your stove’s performance is never compromised by the wind, which goes a long way to saving on fuel and time, as the boil times don’t change significantly even in the windiest conditions.

Top-notch energy efficiency

If you’ve ever run out of fuel a few days before the end of your camping excursion, then you know how inconvenient things can get. And this can be a common occurrence if you are unfortunate enough to get a unit that sucks up the fuel faster than necessary.

Luckily for you, this stove is built to give you the best in terms of fuel efficiency, so you can continue communing with nature. It all comes down to a number of features, including the patent-pending radiant burner, an internal pressure regulator and a heat exchanger.

The benefit of this combination of features leads to one crucial thing, ideal fuel-sipping efficiency in any weather.

Works great at high elevation

While most stoves in this tier work perfectly in plains and beaches, not all of them work as efficiently when you take them up high on climbing expeditions.

This can be a blow to those who might want to camp on high grounds or climbers who go to unparalleled heights, literally.

The good news is, this is yet another area where this stove shows it’s prowess as far as performance in extreme conditions goes.

You can use it up to 11,000 ft, which sets it apart from most stoves that would struggle to deliver at such cold and windy environments, not to mention the reduced oxygen levels.


This not only means you have to stay on the lookout for the stove whenever it’s in use, but it could also pose a serious threat if the unit topples with the hot contents inside.

And the last thing you want is to come from a camping trip with burns. Stability is another thing you can’t afford to get wrong with these stoves.

Thankfully, that’s one less thing you have to worry about with this unit. As long as you are using it with the 1-liter pot, the chances of it tipping over are well close to none, although this will still depend on how even the ground where you’ve placed it is.

What Are The Benefits Of Owning This Stove

When it comes to size and compact design, this little gizmo takes the cake among the smallest and most complete compact options out there that will fit easily on your belt or in your backpack.

Weighing only 1.09 pounds and measuring 8 inches by 6 inches by 6 inches, it’s super easy to transport, you can hardly notice a difference when you add it to your gear.

Its fast boil time ranks it among the top performers. This stove has proved to be capable of boiling a liter of water in less than two minutes in winds of up to 20+MPH, which is quite remarkable.

It’s also super easy to handle, especially considering the small size. But the most important of all is the integrated design, which keeps everything together in one container, so you can have an easy time when using this stove.

Reliability and durable build are also worth noting since it not only helps avoid unexpected surprises at the most inappropriate moment but also saves you a whole lot of money in the long term.

The energy efficiency of this little device to use so little fuel so efficiently with all the difficulties of the outdoors is nothing short of impressive.

Cleanup is the other thing that makes this unit stand out as it is very easy to clean after use. You can simply wipe it clean, and use a rubber-spreading spatula for cleaning the corners, and it should be all clean in next to no time.

Here’s a Tip For You

  • When camping in freezing temperatures, consider keeping the fuel container warm by storing it in clothes or the sleeping bag to ensure the performance doesn’t diminish.


  1. The performance is impressive despite this unit being considerably small.
  2. You can’t beat the fuel efficiency, which makes it great for saving money and ensuring your peace of mind.
  3. It’s stable even with the heavy top, just make sure to place it on even ground for ultimate stability.
  4. You can enjoy fast boil times, usually less than 2 minutes.
  5. It also works great even in windy and cold weather.


  1. The only downside I see with this unit is that it does not have a built-in ignition.


My Overall Opinion

Overall, it turns out this stove is definitely built for every outdoor enthusiast who is serious about bringing fun to outdoor cooking.

It’s light, compact, and easy to tote along, and most importantly, delivers up to its word when it comes to the performance. I really like this little stove.

If you are on the lookout for a small and heavy-duty stove, then I would recommend checking out this little buddy. You won’t believe how well it performs at its size.

Go ahead and grab one for your next trip, whether you are heading down to the beach or on the mountains and anywhere in between, this unit goes with you and will solve all your small heating requirements.
