camping moonFuel Canister Refill Adapter, Isobutane Refill Adapter, Butane Gas Refill Adapter Gas Saver Plus Isobutane Canister EN417 Lindal Valve (Gas Fuel not Included) Z15

After many years of using a canister stove, several partially filled canisters accumulated. Not wanting to risk running out of gas on a hike, a full cylinder was normally used for backpacking. With this gizmo, it was possible to consolidate gas into a few full canisters and toss all the empties. It is also possible to fill two empty 110g. cylinders from one full 250g. cylinder. Given pricing favors large cylinders, this adapter will pay for itself over time. Its easy to use (donor cylinder goes in the sun, cylinder to be filled goes in the freezer) and takes only a few minutes. Highly reccomended.

Threw a few 8 oz canisters in the freezer for about an hour. I weighed a brand new can at a little over 13 oz and everywhere online said 12 oz gross weight is a full can. I used a big 16 oz jetboil canister to fill and brought two up to 13 ounces and the other over 15 by accident. Had to wait for the heavy one to warm up and flip it over to put some back into the large can. This will save so much money. No leaks. Functions amazing, and looks to be cast aluminum with final machining. I'm not too worried about the build quality for how cheap and effective it is.

I have only used it once, but it works well. Seems to be well made with no leakages.

My one significant gripe (so far) is that when the valve is 100% closed the handle doesn't fold over the body of the refill adapter. Maybe mine is "faulty" in that regard, though it did work to refill my small isobutane canister from a larger one. Of course my reasoning for that is that the smaller canister works well for short trips/backpacking where you don't need or want to carry more fuel than necessary. Aside from that the product works well and mine even came with quick instructions on how to use it. I think using it is pretty obvious except perhaps to those who have never done it before. It is recommended and it does help to put the canister we're refilling into the freezer for at least 5 minutes before refilling it from the full or mostly full and approximately room temperature canister. Due to physics that I can't explain well the temperature differential helps the liquid isobutane fuel mixture to flow from the top canister to the bottom one.

you can fill smaller isobutane containers off of large bulk containters that are much cheaper. Or you can fill with cheap butane just need a butane to lindal adapter too. Carful not to overfill past the original weight, or you can overpressurize. 100-110g small isobutane containers are around 200g full gross weight.

Works as expected. Was able to transfer fuel from various stragglers and fill up one 230g can. Yay! That was my main use case; consolidation.I can also see a use case where I actually want LESS fuel for say a short solo trip and can put this little gizmo to use to achieve that.

I’m a pretty avid backpacker and I am always having extra cans of gas hanging out. Use this product. It works awesome totally worth the money. I would highly recommend.

Works well for me.Not getting a ton of gas into the receiver cartridge, but I'm an ultralight camper, so that's pretty much what I want.IMPORTANT TIP: Hold it upside down so the liquid fuel pores down into the receiving canister. Hold it to your ear to hear the progress. Putting receiver cartridge into freezer for couple minutes helps, not sure if necessary.Go easy when screwing in the cartridges, the seal is rubber and you only need them to not leak for a minute. Don't twist them down tight.
