So you're thinking of buying an Alcohol stove for your bug out bag or for hiking.
Before you think about the stove stop and think about the cook pot you will be using.
The reason for this statement is that not all alcohol stoves will work with all pots.
I learned that lesson the hard way. I literally bought 12 alcohol stoves I could not use. Those stoves work perfectly, They are not designed in a way that meets my needs.
In my bug out bag is the Heineken (Heine Pot) beer can pot; because it is a great pot, and super light weight.
Most of those stoves such as the MiniBull Design BIOS & BIOS 4, Batch Stovez 2.0, Zellph Stoveworks Cobalt, etc work well with larger pots that are 4+ inches (10 Cm) and larger in diameter.
If you are using the GSI Dualist. MSR Stowaway pot, etc. All of the stoves above would serve you Very well. I can HIGHLY recommend the BIOS 1&4 by MiniBull Design, and Batch Stovez 2.0 without any hesitation. I have corresponded with Tinny at MiniBull Design via E-mail, and Sam at Batch Stovez many times, and both are honest sellers.
I bought a MiniBull Elite stove (because it would work with beer can pots such as Heine pot. There was a small problem in the Elite that Tinny did not catch during manufacturing. I reported the problem and Tinny refunded the $ I paid for the stove including the cost of postage to get the stove to me.
Both Tinny and Sam are honest reputable sellers.
Now what to do if you carry a small pot such as the GSI Minimalist, the Heine Pot, or the Fosters beer can pot.
Then the BIOS stoves, and Batch Stovez 2.0 stove will not work for you because the flames will run up the side of the pot. When flames go up the side of the pot you are wasting fuel.
Now for the stoves; there are many small stoves you can use. There is the End2End Trail Gram Weenie Pro, Batch Stovez 1.0, and MiniBull Design BIOS micro. These stoves do not need a pot stand.
Then there is a plethora of other stoves that will work with a small pot. Some of them require pot stands, others like the MiniBull Design M1, Bongo Pro, MooDoo (also called the M6) uses legs to hold the pot.
I refuse to use a stove that needs a pot stand or legs. That is my personal choice. I made that decision based on my poor eyesight. If I damage or lose the pot stand or legs that come apart; then my whiz bang stove is useless until I repair or replace the stand or legs used with the stove.
Since none of the stoves I purchased met my needs I started looking at videos on You Tube. I found a design for the Super Cat stove. I liked it because it was very light and did not require a pot stand: when I tried to make one; it FAILED miserably. 16 air holes was insufficient. The stove kept going out because there was not enough air getting in the stove. I refused to make a second row of holes because that would drastically reduce the amount of fuel it would hold. Also I did not want to make more holes in the tough metal that Cat food cans are made from.
I took the design for the Super Cat and moved it over to soda cans so the aluminum would be thinner. I placed the holes closer together so I could get 20 air holes in a single row and the Perfected Super Cat stove works perfectly, and at 4000 feet of elevation one OZ of fuel will burn for 14 1/2 minutes. So these Perfected Super Cat Stoves are packed in my Heine pot to keep them from being damaged.
