The Crux Lite packs the power and performance of bigger stoves without all the weight.

Serious about shaving weight? Take the frame out of your pack, cut the tags off your jacket, and get yourself the 3.3oz Optimus Crux Lite Stove. This incredibly lightweight stove folds down to a super-compact size and comes with a stuff sack that fits in the hollow space under your butane canister. The Optimus Crux Lite Stove's 3000W output boils a liter of water in as little as three minutes, and a simmer knob lets you cook food instead of burning it.

Fits in pockets your phone can't fit in

  • Familiarity:I've used it several times

I love this stove for the price and size! It is perfect for someone wanting to pack ultralite and or they have minimal space. Besides the sheer size of the stove.. It will get a liter of water to boil within 3 minutes. You can't go wrong with this little guy.

I will be soloing Mont Blanc soon and I...

I will be soloing Mont Blanc soon and I am in need of a light stove that works at high altitude. Of course I know that a liquid fuel stove will be better but I am hesitant about the weight and the cost. Will this work at 12-14,000 feet? And just as importantly, does anyone know if I can get canisters in chamonix?

Best Answer

I wouldnt worry as much about the altitude as I would about the cold. If you cannot keep the canisters warm then they will not burn efficiently. Canister stove is definitely the way to go just realize that you might have to work to keep it warm. I dont condone this but, I know holding the canister in between your legs helps or developing some kind of cover that could hold some hand warmers on the canister in a pinch.



  • Familiarity:I've used it several times

This stove is small in size, light, simple, and effective.

I really like that the areas you can touch with your hand are color coded the way that they are, it makes it easy to avoid a hand burn.

The stove stop itself isn't very large, this can be solved by using a smaller pot or keeping a close eye on boiling water.

I got this stove to go with the rest of my collection, and it has been my designated water boiler because it boils water more quickly than my other stoves that I have.


Little beast

Although small, this thing packs a punch. There are more versatile stoves out there but for a simplistic, compact and lightweight option, this guy really shines. It doesn't have a piezo igniter but they don't work well at higher altitudes and will fail eventually over time anyhow. (BIC lighters actually work really well in altitude) Here's what I really like so far.

-Simple design


-Very sturdy feel and construction

-Green Color coded areas let you know what you can touch without getting burned

Cons (not many)

-Small cooking surface (easy to tip the pan over if you're not paying attention)

-Boils water like a champ, not as friendly for cooking and simmering food.

-Doesn't do as well in high altitude/cold temps

It's really quite perfect for what it is intended for. If you are looking for a similar stove with more versatility and features, I would suggest you look at the Optimus Vega. It is a bit larger and heavier but having the ability to invert the canister is a great feature that contributes to greater versatility. When it comes to vital equipment, it's a good idea to have a backup. As the military men would say, "one is none, two is one".

Mighty Mouse

    I was a bit nervous when I bought this stove because I honestly didn't think it could handle the demands...boy was I proven wrong.

    This little guy is tough, durable, and can boil water in about 2 minutes...if you are in a hurry.

    He size is great as I can pack it into either my cup or fuel canister.

    Been using a 70/30 butane/propane mix...seems to be working just fine.

    I see a lot of pictures of the Crux Lite...

    I see a lot of pictures of the Crux Lite appears as if some people are using the jet boil/isobutane fuel canisters. The specs specify butane, so.. can you use the isobutane canister with this stove?

    Yeah you can use any of the mixes that come in the canisters with lindal valves. So the ones from Optimus, MSR, Jetboil, etc. are all good to go.


    Great Stove!

    • Familiarity:I've used it several times

    Love this stove, it brings a whole new culinary aspect to backpacking. I love how compact and lightweight it is. It is also very user friendly.


    The lite model does not fold

      Had to send back b/c it does not fold and therefore does not fit under the gas cylinder in my pot.

      If you don't need a stove that folds flat then I'll bet you will be very happy with this stove as the folding one is excellent.


      Mt. Shasta



        Blown away by this stove. Boiling water, making oatmeal, or whipping up a desert, this stove can handle everything. From boiling to simmering, it's spot on.

        My goal this summer was to go ultralight and this stove was an obvious choice for hitting that objective. It packs away in my cookset. It's absurdly light, but it's bomber. And it's a powerful son of a gun! Fires up every time. Haven't had it in sub zero temperatures, but it was completely fine in high 30s low 40s.

        Sure, the jetboil can whip up water about 30 seconds faster than the Crux Lite, but the crux gives you much more variety and manageability when you're cooking. Highly recommend it.


        great stove

        • Gender:Male
        • Familiarity:I've used it several times

        very happy with stove and when I bought it here, it was $27 so a great deal. It boils water fast and very stable.



          I have used my stove over 60 times out in the elements. It has not failed me once!!! I would for sure recommend this stove to anyone.



            This little guy packs a lot of heat! It's small, not made for putting big pots on there but I've done it (very carefully)! It's great because it's small, light, very strong, and super super portable. I put it inside a backpacking mug and toss it in my bag. If you are car camping I'd recommend something bigger, although I always bring it just for coffee while breakfast is cookin!

            Does anyone have the folded dimensions of...

            Does anyone have the folded dimensions of this stove? Specifically, I'm wondering what the height is, and the diameter when the arms are folded in. Are the specs listed here with arms open or closed, and is it 3.3" tall or diameter?
            I'm looking for a stove that will fit inside my GSI Pinnacle Soloist laid on its side in the hollow between the cup and fuel can.

            Edit: I've looked at the regular Crux, but would prefer to avoid a potential failure point of the hinge on the burner (though I admit it is pretty trick) and want to keep this purchase as inexpensive as possible.

            This stove does not fold at all. It is lighter than the regular Crux that folds though. The difference is a stove that folds into a smaller space versus a simpler stove that weighs less but has a larger packable footprint.


            Don't try this at home!

              I can't really add anything to what's already been said here about the technical details of the stove- boiling times... weight, etc... It obviously compares well to other, similar stoves, and those reviews offer great reasons to consider buying a Crux Lite. But I do have something unique to offer that a potential buyer may want to consider in addition to the other qualities mentioned...

              Last week, I stepped on mine.

              I weight well over 200 lbs...

              Fortunately, I can report that both stove and owner are doing well, and I am now a fan for life of this stove. It is as strong as they come.

              Why does it say that the boil time on this...

              Why does it say that the boil time on this stove is 60 min? Also, the weight is the same as the regular Crux Stove according to the stats?

              Since it says 3 min to boil a liter, I'd say they mean how long it will run on one gas bottle.

              I believe that's correct- I get about an hour per bottle with mine...
