MSR Reactor Stove: The “Pocket Rocket” of Outdoor Cooking

Written by Kane Dane

Deciding on the best cooking stove for your wilderness trips can be somewhat confusing as there are many options available that have different features and use different sources for fuel. However, if you require a very efficient, fast system that melts snow or boils water almost at the drop of a hat, you would be very hard pushed to go past the MSR Reactor Stove System.

In the words of the manufacturer, the Reactor “combines high-performance cookware with innovative design, making it the quickest, most efficient stove system MSR has ever made”. Considering the reputation of the manufacturer, for producing other high-quality outdoor equipment, that is a high recommendation, indeed. To back up their words, they include a lifetime warranty on their product which is produced in Seattle, United States.

In this article, we will discuss what makes a Reactor stove unique and consider various MSR model reviews to discover why there is nothing that will beat the MSR for rapid heat production in the outdoors.


The Reactor is the first canister fuel stove engineered to utilize maximum benefits of radiant burning for use in outdoor and alpine regions. This new technology cranks out heat rapidly and keeps constant pressure for optimal fuel regulation and consumption.

This combines high-efficiency heating in one very compact, simple-to-use-system. New generation technology takes on heating of the liquids and cooking one pot meals with speed, efficiency, and convenience in the outdoors to a new level. Read on to check out some essential features of this cooking stove.


The stove is stuffed in a compact 6 x 6 x 7.5 inch box. With a weight of 1 lbs. 3 oz. ounces, the main Reactor stove accompanies a 1.7-liter pot, a top and a small sponge that is helpful for drying the pot before packing the stove in it and cushioning the stove amid storage. The stove utilizes IsoPro fuel canisters that have a weight of 8 ounces each. The entire package is compact and elegant.


The reactor 1.7L is pretty large, yet at the same time packs well. It has a weight of 530g when stowed which is blundering on the weighty side. While some people incline towards functionality compared rather than an ultra-light gram, most people will concur that the reliability, fast boiling, and fuel efficiency, are worth it, regardless of the weight or size. The cooking stove was packed, assembled and unpacked and generally dealt with as it would have been amid an extended wilderness adventure.

Design and Durability

In the case of the Reactor, an extremely lightweight yet durable disc of “Fecralloy” is used. To manufacture the special discs used in Reactors, an open cell foam is immersed in a slurry of Fecralloy and left to solidify into shape. This is then baked at a high enough temperature to burn off the foam leaving a rigid open cell structured alloy material – Fecralloy. Discs for the Reactor are then cut into shape for the special burners called Burner Screens.

The pot is durable and strong—due to its sturdy, wide stance and is able to resist general mishandle like being full at the base of a loaded backpack, kicked around stones or rocks and flung off the burner a couple times. Even if while using and you notice that the handle fell off, you can take it and quickly snap it. Amazing! The Reactor’s stove unit, which screws into the stove canister, features an aluminum mesh within the outside edge that is dentable and flimsy.


This combination of flame and screen heat produces both radiant and convection heat. Radiant energy transfers from one material to another without changing the ambient air temperature. Convective heat also plays a part of the Reactor system which is where the heat is transferred via hot air. These two modes of heat transfer, utilizing convection and radiant heat, produce such efficiency that a liter of water boils in approximately three minutes. That is pretty extraordinary!

Fuel and Efficiency

Not only is the state-of-the-art Reactor stove very wind resistant, internal regulation of fuel pressure creates a consistent flame in all temperatures and excellent performance throughout the life of the fuel canister for greater energy efficiency. The MSR® Reactor is not sold with a fuel canister, but these are relatively easy to purchase from most outdoor stores throughout the world.


Reactor stoves can only be attached by appropriately threaded, self-sealing canisters. It is recommended you use an MSR IsoPro Isobutane-propane gas canister where possible. MSR recommend using a blend of 80% Isobutane (with the purest Isobutane – 5% or less n-butane) and 20% propane.

This makes for a cleaner burning fuel that helps to maintain higher internal pressure, which is more far more reliable throughout the life of the canister and gives superior performance at higher elevations or in colder weather. Other brands often use lesser quality gasses and a 70:30 blend Isobutane: propane which will reduce the performance of any gas stove. The fuel is also very clean burning so there are no nasty smudge marks left to clean up on cookware.


The pot is billed to be a 1.0L pot, and if you completely fill the pot, obviously you should be able to put a liter in it. However, MSR suggests that you put just 0.5L in the pot at once. What? Only half of the pot’s capacity? What gives? Indeed, the Reactor is a standout amongst the most powerful stove available for backpacking.


You can get a fast boil, a boil that could reach the brim of the pot in no time, and displays an undeniable scalding danger. The weight of the stove canister could project through the rooftop. Your stove could erupt or carry on in sudden, risky ways. Not something you do want to risk.

Nonetheless, a cautious user, a user who is able to keep the stove turned down always and is able to watch the pot properly, could effortlessly boil 0.75L at any given moment or perhaps 0.8L. But, in the event that you boil above 0.5L at once, you are conflicting with the manufacturer’s suggestions and you do as such at your own risk. The outcome of a bubble over could be very serious if your canister ends up plainly overheated. Be careful!

Ease of Assembling and Using

Setting up the unit is super simple. You have only the stove, the pot and a suitable gas canister to assemble and the MSR Reactor Stove system is undoubtedly a pocket rocket when it comes to this stove’s ability to heat water and liquids rapidly, thereby effectively. It is second to none when it comes to boiling water or melting snow. Within 3 minutes you can be pouring a hot drink or soup, which in a cold outdoor environment could be a life saver.


Because of this, super heating efficiency, however, the Reactor is more suitable for heating liquids or one pot meals that contain a fair amount of water. Dehydrated meals that can be reconstituted in their pouches would also be ideal for easy use and clean up. One pot meals are also successful, providing they are water based.

When it comes to meals that require slow simmering, however, the Reactor proves more challenging as the Reactor does not ‘do simmer’ so well. It is not suitable for any sort of fry up as there is no suitable lower profile pot that fits the burner disc.

Value for Money and Guarantee

The Reactor is costly and retails for approximately $200. Its burner is somewhat larger compared to the Windburner. We believe that the Windburner is a vastly improved value and has great features, particularly in case you’re searching for something around 1L size.

However, at an approximate price of $200, we believe that the MSR Reactor is somewhat costly for the value it gives. However, the extra cost isn’t a problem, it is still a great choice if you’d like to enjoy some simmering functionalities in a canister stove. Good incentive for money at approximately $200!

In regards to the guarantee, the product has a limited lifetime producer’s guarantee. However, we are certain that the sellers by one means or another have a guarantee for defect items. So in if the cooking stove gets spoilt, you can send it back and get in contact with their customer service. Indeed, even on Amazon, there is a warranty for such defect items.

The greatest performance advantage of the MSR Reactor results from the management and control of airflow. The Reactor’s burner pulls the required air through vents situated on both sides of the knob that controls the flame intensity. This ensures that mixing of the fuel, air, and gas, occurs inside the stove area only.

When in place on the stove, the integrated heat exchanger fused to the 1.7-liter pot completely encloses the radiant burner, ensuring maximum protection even in the most extreme winds. With this unique windproof design, this gives the much advantage over any other gas canister stove.
