For regular backpacking trips I've found this little doohickey to be priceless. Texasbb, so, let me get this straight. Does this device allow me to transfer remaining fuel from, say a quarter full small canister to a larger partly empty canister, or vice versa? And you say it works well. It addresses ne of the most vexing problems I have in my gear closet. If it works, I want one. I don't know how many partially full canisters I have laying around in my gear closet, none of which I'm sure just how much fuel they have left in them. Thanks for your response.

The instructions make sense. Freeze the destination canister so it’s internal gas pressure is low. So the less full warm canister with its higher gas pressure will push the liquified fuel down into the destination canister.
Super clever!

I don't know how many partially full canisters I have laying around in my gear closet, none of which I'm sure just how much fuel they have left in them. It does work. I have one. I think the reason they are not more common is that there are dangers to them. Google about them. There are YouTube's as well. The quick version is use likes with likes. MSR to MSR. Peak to Peak, etc. Don't cross brands because they may have a different mix and different tank strength requirements. It is OK to use a large MSR to fill smaller MSR or vice versa. It would be better if you had a scale. My small MSR are filled at 113g (on my scale) The results are I have been always leaving with a full tank and I empty tanks down to no liquid and can use the valve to remove any pressure then punch a hole in the can. And the temp tip from High Sierra Fan

P.S. If you get the valve it is pretty small and not too heavy. Just a quality thing. I have come to regard it as a small jewel (<-engineer brain talking). I have heard that some carry on long trails. They use it to scavenge fuel. I hear you can find a way to top off your can at things like hostels from discarded almost empties or donations.
Edit: And again the danger thing. The cans are only expected as one time use containers. The multiple refill life of the cans is basically unknown. In normal mode I do buy new cans (now almost just buying more fuel) and the partials I've only used for a few refills. I rotate. Newer cans are the working cans. Older cans for refilling and eventual disposal.

As others have said, yes, it works. Yes, you can send fuel either way, from small to large or large to small. I just set the to-be-filled one in a bowl of shallow ice water and do the transfer. You do have to be careful not to overfill it, and that requires weighing it and sometimes reversing some of the fuel.
As others have said, the cans are intended for a single use, but I'm comfortable reusing them at least a few times as long as I'm careful not to overfill.
It's the only real solution I've found to the partial-full can problem.

Thanks folks. I think I'll give it a try.

This thing works. I went from 8 partial cans to 3 almost (I think) full cans. The MSR cans finally weighed 207 gms, the Jetboil and Snopeak weighed 170. How's your Korean?

Good info. I need to get one.
For car camping, we use a propane stove. That has the same problem, as we don’t have room in the car for one of the larger refillable canisters. I think I did see somewhere where you could buy refillable quart bottles, and I need to look into it. Or something between that and the 5-gallon or whatever those standard pods are. The thing is, it seems like these days the only way to fill a camping bottle is with the exchanges (drop off an empty, get a full).

I can see that as an issue for thru hikes. For regular backpacking trips I've found this little doohickey to be priceless. I can buy the bigger "bulk" gas canisters and just refill the smaller ones I take on trips. Wow, that's awesome. I had no idea such a device existed. I've always just collected the near-empties and run them dry while car camping. (When I car camp solo, I mostly just cook with the BPing stove.)

I have one of these to be able to use the green propane cans with my MSR Pocket Rocket: www.amazon.com/gp/product/B072QXKVJP/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1Seems to work OK but I have only done brief tests. I figure you can get the greens in a lot more places then an MSR can. Also if need be it should work in the very cold. This is more for car camping.
P.S. Do NOT use this and a transfer valve to try and fill a butane can with propane. BOOM. There is a reason the green cans are so heavy duty.
I have one of those for car camping, maybe even winter camping if not too far. Mine you have to put it on the stove first to prevent leaks, I. I have used it on the MSR windpro.

Okay, I got the little gizmo and successfully consolidated 7 cans to 4. I was careful to use my scale and leave about an ounce of slack in each. Marked the cans with their new fuel weights, and I'm good to go. Now, how many ounces do I need for 8 days.... ?
