Does a Soto Amicus fit a jetboil cup?

I don’t know about the fit of the Amicus, but if needed, you could consider cutting slots in your JetBoil pot. I don’t remember how I cut the slots. a Dremel maybe? This moves the flame closer to the pot bottom and protects it from the wind.

Here are pics of what I did. I actually like it better than the JetBoil standard pot/stove interface. It is very stable, yet easy to separate.

Michael – nice mod!  Looks factory.

Dan – Hope you like the Amicus…it’s supposed to be a really nice stove.  I have a Windmaster and love it. I’d replace it with another one if needed.  I suspect it’s 3-pronged pot support could be easily modified to fit the JetBoil.

The amicus has a 4 prong support so that would make it very easy to cut the slots with a saw.

So, got my Amicus, and certainly impressed. Excellent build quality, and …wind resistance certainly seems to be true (at least compared to my brs 3000t).

I am just overloaded with choices right now. So,6 items to choose from right now (amicus, brs3000t, evernew 600ml pot, jetboil .8L pot…and…for winter…jetboil 1.8L pot vs open country 2 quart nonstick pot).

I went ahead and did 20 test boils between the 4 combos possible for summer use stoves/pots. I learned:

1. Brs:Amicus have about the same fuel efficiency in kitchen use (no wind).
2. Amicus: mid vs high power settings: High is only about 4-5% less fuel efficient, but saves about 25% off boil time (2:05 min vs 1:35 for tap water).
3. For a 2 cup boil….there is about a 1.5g fuel savings if I go with the jetboil vs the titanium evernew pot.

So…the heat exchanger definitely works on the jetboil, and titanium, though lighter…is just not as effective at heat transfer as aluminum. (I’m preaching to the choir on most of this data).

I am also now leaning to go closer to high power on the stoves to get faster boil times. Previously I was going towards the lower end on settings for fuel efficiency…but I’m just not saving enough fuel to make it worth it (especially since I’m usually with a family doing multiple boils).

But….I previously had my .8L jetboil sol TI cup…which…on the higher output setting of the brs, melted some of the fins. I’m hoping that now with the Jetboil aluminum cup that has better welds and heat transfer, that it won’t happen again, though its still on the back of my mind.

Minimum setup: BRS with Evernew: 3.63oz ->

Maximum weight setup (amicus/jetboil): 5.31oz jetboil cup with 2.77oz amicus: 8.08oz

Anyway, it boils down to (pun intended):

Jetboil vs Evernew: 5.31oz vs 2.74oz: Jetboil saves me 1.5g of fuel per boil (so..4.7g vs 6.3g for 68° 2cup water), plus faster, also packs nicer, but weighs 2.57oz  heavier. So, I would have to boil 48x to make up for the weight. I do usually just max 6 day trips so…that wont happen on any trip.

Amicus vs BRS: 2.77oz vs .89oz. Mainly…quality goes to amicus…its just a nicer stove. Built in piezo, solid, wont bend to heat, 4 long prongs, wind resistance. BRS just has weight going for it.

Anyway…so I’ll have to contemplate all of that for a while.

Then, for snow melting…I’ll have to go with an Amicus…b/c a BRS is not going to support the weight of a 1.8L pot for extended periods..plus its just too small.

I really wanted the NON-nonstick open country 2L pot, but it looks like they don’t make them anymore. Its just $17 on amazon though for the nonstick version ->

Vs: a 1.8L Jetboil, which I can get for about $40 on sale. ->

I’m…not positive on the weight differences between the two (after I cut down the jetboil weight (find a better lid, don’t take cup, cut cozy, etc).

Anyway….last comment. On the Amicus…currently looks like this with a jetboil ->

I could cut 4 slots with a hacksaw (I don’t have a dremel), which would make the stove be closer to the pot. It would definitely help with pot stability. I would assume it would help wind efficiency and probably be slightly more fuel efficient. I am worried about the flame being even closer to the jetboil fins though if I use high power setting on the amicus…..I could just be overly worrying about it though. Thoughts?

Can anyone take a guess if heat exchanger rings will still function well of you cut all the way down to the pot surface and have to remove 2 fins in each spot, so instead of a full ring you have 3 separate sections?

Nice experimentation. I’ve burned a bunch if fins off of two times jetboil now, so I’m thinking about the Al replacement cup as well as other pot/stove combos. I will say I’ve happily used a jetboil to for the last 7 years about and somehow never thought to nerd out on anything else, but I guess the time has come ;)

Curious if you got the chance to weigh the .8 Al cup vs. the time cup? Also, what soup cap did you use? JB lid is pretty useless IMO. I do think it’s something specific to the ti fins that makes them vulnerable. I’m thinking about getting a regulated Soto windmaster and matching it to a .8 liter jetboil cup. I like the  dremel idea too.

@popeye

I wouldnt mess with the fins. My experience is that once a couple of them go, there is less heat dispersal and the others start to burn off too, esp if they get wet.

And finally, anybody use a moulder strip with a Soto windmaster? Is the stove too tall for effective heat transfer?

And finally, anybody use a moulder strip with a Soto windmaster?

Short answer: Yes

Although the copper strip works best with a stove with a small burner head that concentrates the flame, QiWiz found that making the top of the strip a bit wider to capture more heat from a broader burner also works well.

I once did a test with a Primus Trail Classic which has a very large burner head that is in a ring configuration and the strip did not work well at all. However that is a stove that no respectable UL backpacker would be carrying anyway.  ;^)

Using a 1.8 liter JB pot I would stick with using a JB Minimo stove simply because of the stability issue.

For a 2 cup boil….there is about a 1.5g fuel savings if I go with the jetboil vs the titanium evernew pot.

With a good setup it normally takes about 5g to boil 2 cups, so this is a huge difference. On a short trip not a big deal… significant if aiming for best fuel economy on a longer outing.

One thing I will add about the BRS-3000T stove – DON’T run it on a high flame setting when using it with a JB pot and riser disk. The several failures I’ve read/heard about involved just that. I use mine at a medium-low to medium flame, and it works great. Too high a flame setting can lead to flame quenching, and probably overheating of the JB fins. It certainly wastes fuel. No need to be in a hurry here, a minute or so longer boil time is insignificant…

I’ve burned a bunch if fins off of two times jetboil now, so I’m thinking about the Al replacement cup as well as other pot/stove combos.

How did you burn your fins off? With the jetboil stove? Did you…try and melt snow with a Jetboil Sol TI cup or something?

Curious if you got the chance to weigh the .8 Al cup vs. the time cup?

Sure…there is a 1oz difference. Jetboil originally stated that there was a 2oz difference between a Sol Al vs Sol TI…but it was super shady. On the TI they weren’t counting the weight of the cup or something and on the Sol AL they were.

Anyway, weights:

Sol TI cup: 3.87oz   .8L AL cup: 4.7oz

Jetboil lid 1oz   soup cup lid: .28oz

Jetboil Cozy: .92oz, cut off the webbing: .74oz   cut it in half   .33oz

Jetboil cup: 1.13oz   (I don’t take).

So my current jetboil cup setup is 4.7 + .33oz + .28oz = 5.31oz

Also, what soup cap did you use?

Just to clarify your statement….so…after my test boils, I would get 4.7g for 2 cup boil with a jetboil (with either stove)…so…yeah, about 5g out in the wild. But….with the evernew short/wide 600ml pot, it would take about 6.3g. Are you saying….that with other NON-jetboil setups you should still be getting 5g boils? Or are you saying….yeah, 5g boils with a jetboil (heat transfer fin cup) is standard.

BRS-3000T stove – DON’T run it on a high flame setting when using it with a JB pot and riser disk. The several failures I’ve read/heard about involved just that.

Yeah…that is exactly what happened with mine. During a boil test, with my riser disk, brs3000t and Jetboil Sol TI when I turned it on high…it quickly burned the fins.

But…..do you happen to know if the other failures you heard about were with SOL TIs are also with Aluminum jetboil cups?

I think the high output brs is even hotter than a full power amicus…and definitely the flame is “wilder”..and wider than the amicus. The amicus high power is definitely more “under control”.

BRS:

Amicus:

Basically…still a question in the back of my mind if how dangerous it would be to use an amicus at higher power with a jetboil Aluminum.

Anyway…I’m now contemplating and selling the 600ml evernew pot…to get a 600-700ml Evernew “tall/skinny” pot. One thing I don’t like about the 600ml pot is that I can’t store a fuel canister in it (you can if you use the original lid but it still doesn’t pack great). With something like this ->

https://www.traildesigns.com/products/evernew-760ml-ultra-light-titanium-mug-eby270r

I could store fuel canister plus stoves no problem. I would assume that it would be even worse fuel efficiency though since its a skinny vs wide pot.

I would hope since its probably very similar to the jetboil cup width that the soup lid would work with it…but…just a very small diameter change would make it not work. Only one way to try though.

Just to clarify your statement….so…after my test boils, I would get 4.7g for 2 cup boil with a jetboil (with either stove)…so…yeah, about 5g out in the wild. But….with the evernew short/wide 600ml pot, it would take about 6.3g. Are you saying….that with other NON-jetboil setups you should still be getting 5g boils? Or are you saying….yeah, 5g boils with a jetboil (heat transfer fin cup) is standard.

Yes, 5g with JB (Reactor, Windburner also) is easy to achieve, but more fuel will be consumed for other non-HX pots, such as you experienced with the Evernew.

However, a MiniMo pot/BRS with Gary’s riser disk and his suggested flame output level is also extremely efficient… best efficiency I ever achieved, which was 3 cups using 6.3g of fuel, so about 4.3g for 2 cups (generic test variables similar to other more well-controlled tests…)

Fuel economy is almost certainly going to suffer with a tall/skinny pot.

I have reckoned for some time that JB intentionally limits the output of its burners to protect the fins so I proceed with caution when using other stoves. Full bore isn’t necessary anyway.

Thanks for the reply.

However, a MiniMo pot/BRS with Gary’s riser disk and his suggested flame output level is also extremely efficient… best efficiency I ever achieved

Yeah….makes sense…the wider pot of the minimo would be more efficient. But…I have been trying to google actual weight of just the minimo pot itself (or at least, the components of it (lid, cup, pot, sleeve) and can’t find it.

From what I can guess…is that a minimo just the pot weighs about 7.2oz? I’m not sure…but if thats the case, it means it weighs 2.5oz more than the standard .8L cup. If that makes efficiency go from 4.6 to 4.3g per boil….that wouldn’t be worth it to me at least.

But….going back to the evernew vs jetboil….Yeah, short trips would definitely lean towards the evernew, but…I could see myself switching to the jetboil for certain cases.

For example….with the evernew, I would get about 17 2 cup boils on a 110g canister. With the jetboil, about 22.  So…there are certainly trips where my estimated boils could be between 17 and 22 (especially with a group), and the jetboil would certainly win there because I wouldn’t have to carry a 2nd 110g canister and its fuel. 1 110g fuel canister is about 100g of metal weight…or 3.5oz, which just the metal alone is more than the 2.5oz difference between the evernew and jetboil pot.

Ok, so…I used the moulder strip setup on a winter trip I took with my son two weeks ago.

I was super impressed with the moulder strip itself! Wasn’t super cold…the low was around 15°. I did preheat the fuel can a bit in my lap for a few minutes, but with the strip, I had no issues with power with boiling water and melting snow for multiple liters of water.

This is a 110g canister with the soto amicus and a jetboil 1.8L cup. Its resting on a snow claw shovel and the foam from the inside of one of my down booty overboots.

It took me about….3 seconds to realize that this particular setup was way too unstable. I really need to get a jetboil fuel can stabilizer (I gave mine away since I never used it in 3 season camping). And…I still need to make 4 slits into the bottom of the jetboil ring for the amicus pot supports to rest into ( I wanted to test out the system first before I permanently modified the jetboil cup).

I also want to use the 225g fuel canisters…but…my moulder strip isn’t long enough. I would hate to ask Bob for another one. Not sure where I can find 1″ copper plate strips? Any ideas?

Ok…as a followup…now I am much more setup for winter! (stove wise).

First, I was able to borrow a friends dremel with a grinding wheel. It was fairly easy to grind away 4 slots for the amicus, and then use a metal file to smooth out the cuts. I went ahead and did it to both of my jetboils (.8L and 1.8L).

Now….the cup is much more stable on the amicus. I set the cup on the amicus, just rotate slightly and it slips right into the grooves. Now I don’t have to worry about the cup not being centered on the stove, and slightly moving the setup won’t cause the cup to slide off the amicus.

For stability…. a fellow forum member gave me a MSR fuel stabilizer, which is definitely nice, though a bit heavy for what it is. I was able to acquire some 3d printed clip on can stabilizers, which…are not as stable, but weigh very little ->

 They weigh so little I might even bring them for summer camping!

I was also able to make various length copper strips to handle all of my possible setups (100mg/200mg fuel cans, brs3000t, amicus). Now…I am ready for winter! Too bad its another 8 months away now.
