Lightest collapsible wood burning stove on the planet - the FireFly Stove on 02/27/2012 15:25:27 MST Print View

June 2015 UPDATE:

Stove, trowel, and saw info:

Before placing an order, please check the shipping page on my website (a link to this page is available on any page that you order from).

Try and find a more ultralight highly functional and pot-adaptable woodburner that easily assembles and comes apart into a neat, tidy flat package. Now laser-cut and tweaked to work with an even larger variety of pot and pans! Has a completely unique FlexPort option for feeding longer pieces of wood into the stove for longer burns, OR closing the Port for a quick chimney burn.

Titanium sides and stainless steel mesh shelf - weighs 2.7 ounces, 2.8 with a FlexPort! Standard with an 8 mil ziplock pouch. Optional reinforced tyvek pouch with velcro closure. Multifuel (Esbit and alcohol), grilling, and baking options.

See more information, links to videos, and how to purchase at:
Videos include demos of assembly and disassembly as well as getting all fired up. Available FlexPort, MultiFuel, Grills, Bake Kits, Esbit-only burners, and other options also fully described.


The vast majority of pots that backpackers use will work well on the stove. I have tested the stove with light pots up to 6" in diameter holding up to 1000 ml (32 ounces) of liquid. In the event that you want to use a cooking mug or beer can pot that is too narrow for the built-in pot supports, you will need to get a pair of my optional pot supports. The "narrow-light" supports insert into the lower holes and notches to span the stove in parallel at the same height as the built-in supports. They will support a light pot with up to 600 ml (20 ounces) of liquid. They are also perfect to support one of Gary's titanium grills (available at If you want to use a really wide pot or light frying pan (more than 6 inches in diameter), you will find that my optional "wide-heavy" pot supports are helpful. Using the higher holes and notches, they make an "X" above the firebox and add another inch of room under your wide pot or pan, for additional air flow and easier fire feeding. They will support a light pot or pan with up to 1000 ml (32 ounces) of liquid.

You know you WANT one . . .

What about the Pocket Ti Stove (wood burner, alcohol, esbit) at 1.975oz 56g. I'm thinking of getting one of these.

I'm not connected with the company in any way other than as a customer.

I was going to post the same link. Found it last night researching wood burning stoves. I think the FireFly could benefit from the same circular punches to get the weight down even more.

I wonder if a 2/3 scale version of the FireFly would be more attractive to Heinie/Fosters' can users.

The first of this type of collapsible stoves I came across was the Little Dandy Wood burning stove, commonly called the Nimblewill Nomad after its designer :
that does have some slots on the sides but a solid bottom .

Mea Culpa on the "lightest on the planet"; answers to questions and comments on 02/27/2012 20:34:35 MST Print View

Oooh how I hate to be wrong, but I guess I have to admit that the Pocket Ti stove is about a half-ounce lighter than the FireFly (at least if you don't use the tin it comes in). I had not found this stove when I did my research on woodburners, so I guess the FireFly is only the second lightest. I don't know how long the Pocket Ti has been available, but the current site lists it as a 2012 stove, so it may not be that long. The Pocket Ti appears to have achieved this even lower weight by having an open side/door and probably by having a smaller sized firebox overall.

Snide comment alert: If you watch the video on the Pocket Ti, the ability to use multiple fuels is nicely demonstrated, but it's also shown in the video that the addition of an Evernew titanium trivet to the top of the stove helps create air space between the top of the stove and a pot (if you like a squat pot like I do) and improves draft and performance. The trivet weighs 16g and costs an additional 12.99 pounds. With this modification, the Pocket Ti would probably draft as well as the FireFly, weigh as much, and cost more. Good to get that out of my system.

Anyway, at the risk of encouraging dissent, here are some of my thoughts on woodburning stoves in general from having made and used many of them over the years: [1] ignoring stove weight for a moment, a larger firebox makes a stove easier to light and easier to keep going; [2] you want a good air inlet under your fire and a good air exit above your fire but under your pot. So the trick in making a light woodburner is to satisfy #2 while making the firebox as small as is reasonable (but not too small) out of the lightest material you can. Titanium is what works best as a material, but adds expense (Oh well). The current size of the FireFly is as small as I would want to use myself. I could make a smaller FireFly, but it would be less stable in use and harder to keep going because it would not hold much wood. A 2/3 size FireFly would save maybe .75 ounces but would not work well IMO. Your opinions may vary.

I don't see the dimensions of yours but the British version is about 4" high and 2.8" wide at the base .
That 4" looks to me to be the full height , not the height of the fire box..
As you can see from the video it is designed to take a Trangia stove , so not very big for a wood burning stove ...

FireFly dimensions on 02/28/2012 15:54:54 MST Print View

The FireFly firebox is 3.25 x 3.25 x 3.75 inches, which works out to about 40 cubic inches. Small but not too small.

3/2/12 UPDATE: Firebox now 3.25 x 3.25 x 4.00 inches, for a 42.25 cubic inch capacity

Compared to the "pocket stove", the FireFly has a 65% bigger firebox, as best I can calculate from the information on their site. 'Nuff said. Defense rests. ; )

I like the your stove better. on 02/28/2012 17:33:44 MST Print View

The Tyvek sleeve is a great idea. The difference in weight of the actual stove just doesn't matter if it holds a little more fuel. All the options may make great marketing material but the reality is you either use it to burn wood or it is a glorified wind screen for alcohol or Esbit.

I may buy one Robert because I miss my zip stove.

Good news, Bad news on 03/02/2012 05:18:08 MST Print View

Good News:
I have tweaked my design in such a way that firebox size increased by 5% with no increase in stove weight. Firebox is now 42.25 cubic inches. I have also improved the design of the optional tyvek pouch, adding only 2g to the original 9g weight, but the pouch interior is now completely reinforced with fiberglass mesh tape, for much greater durability. Now we're cooking!

Bad News:
Just ordered more titanium for stoves and trowels. Prices have increased a lot. I'm holding firm on trowel prices, but have had to increase the price of the FireFly stove by $5, since each stove uses quite a bit of Ti to make. The improved redesigned pouch is now optional rather than included. You can use a plastic ziplock or other DIY pouch if you like, but the tyvek one I'm making now is really nice.

Free stove floor upgrade; new FuelPort option for FireFly Stove on 03/12/2012 11:09:32 MDT Print View

3/20/12 UPDATE:

I have been able to find some 1/4" by 1/4" stainless steel mesh in an affordable quantity (as opposed to spending $$$$ on a full roll of it). It has replaced the galvanized steel mesh I have been using for stove floors. Everyone who has a galvanized floor will get a free upgrade from me. You're welcome!

The other thing I've been working on is a "FuelPort" option that will allow you to feed longer pieces of wood into the stove once you have your fire going. I am happy to say that this option as well as the even more astounding FlexPort option is now available. A video of a FlexPort prototype is also available on my website.

* In the FlexPort video, you will see that I put the ventilated ti floor (another new option, along with a perforated stainless steel floor) on top of the old mesh floor. This is not necessary; you can just use the ti floor by itself, saving a few grams.

New stainless steel mesh floor; FuelPort and FlexPort options for FireFly stove on 03/20/2012 11:21:34 MDT Print View

Well the wait for the new FireFly stove floor material was worth it. I now have the 1/4" stainless steel mesh in hand and it is really nice. It replaces the previous 1/2" mesh as the new standard FireFly floor. Replacement floors went out this morning to early adopters as a free upgrade. Fits snugly in floor and actually tightens up the set-up stove as a result. No increase in stove weight. Less room for twigs and embers to fall through the floor mesh. More durable. What's not to like? Nada! Here's me admiring it.


And, NOW available on website are some additional options:

A FlexPort, so you can have your cake and eat it too - have an open FuelPort when you want one, and a closed FuelPort when you just want a quick chimney stove burn. Adds only 4 grams to the weight of a FireFly stove.

I will also have an optional floor to reduce through-the-floor ventilation when using a FuelPort. This is a notched titanium plate.

All of this is live on my website for your perusal and even purchasing ; ) - Now we're cooking!

Air Flow on 03/24/2012 08:08:06 MDT Print View

I am wondering what the benefit to closing the fuel port door. Is there really an increase in efficiency by closing the fuel port door? My experience with paint can wood stoves is that the more air the better they worked. I think this is why Zelph ended up with an open mesh design for his folding wood stove. I think the benefit of the FireFly is increased volume of the fuel box and ease of adding wood as you burn. I was able to barely boil water with a single fill of wood and always seemed to need to add more wood.

This was also part of the pleasure of burning wood. The comfort and pleasure of working the fire.

Design matters on 03/24/2012 09:34:51 MDT Print View

Yes, a chimney design is more efficient, wind resistant, and heat concentrating. Most "paint can" hobo stoves do not have enough bottom ventilation.
My experience with wood burners is that the best design has air coming in from UNDER the fire, rising THROUGH the burning wood while being sheltered from any wind, and then EXITING freely above the burning wood, right under and/or around your pot. The standard FireFly does this very well with its open mesh (above ground but) under the burning twigs, a protected chimney of a firebox with 4 solid sides, and plenty of exit room under your pot.
When you create a side opening for feeding in longer pieces (aka my FuelPort and FlexPort options), you want air coming IN that Port to feed oxygen to the fire, so my notched Ti floor reduces bottom ventilation, so that the fire is now fed air about 50% through the bottom, and 50% through the Port.
Watch the videos on my website and this may be more obvious.

Wind Screen on 03/24/2012 20:37:45 MDT Print View

Robert: Have you experimented with adding an additional standard wind screen around the stove. You would want to cut judicious air inlets around the base but that might give you even more heated air and wind coverage for complete combustion while adding < 1 ounce.

Wind screen ideas and comments on 03/24/2012 21:10:49 MDT Print View

I guess in my use of wood burners over the years I've been less concerned with wasting heat when burning wood than when burning alcohol or Esbit, because a twig fire burns pretty hot and I usually have all the twigs I need. So I have not generally bothered with a wind screen when wood burning.

BUT, in a windy spot, a windscreen of the type Kevin describes would definitely help heat your pot more effectively. You would need to leave an opening for feeding twigs in and maybe prop it up on some small rocks or sticks or cut openings in the bottom so that air could flow in to the area under the stove mesh.

BTW, all three FireFly videos on my site and YouTube have been updated to show the new floor, FuelPort, FlexPort, and all the other cool new stuff. This stove is HOT!
