Adapter Gas Refill Adapter Butane Refill Adapter Filling Butane Canister Adapter for Backpacking Camping Stove

This device allows you to refill an isobutane canister (threaded for backpacking stoves) from a cylinder (pressure activated tip). It works really well. I used it extensively in Chile and Argentina. In many places we could only find the cylinders because car camping was more popular in those areas. Even if we could find the canisters, they were often double the price of the cylinders. I would put the cylinder in the freezer for about an hour and then do the change, though I also did it without freezing it and I can't say I noticed much difference. It usually took about 10 minutes to finish. I was often able to get about 95% of the gas moved, though there was always a little left over. One tip is to periodically stop and then restart again. I think perhaps the diaphragm on the canister gets ice build up or something, I don't know, but it wouldn't sound like the gas was moving. I would take the cylinder off, try it again, and the gas would start moving again. The exchanger is very small, I kept it in my money pouch, and it has no moving parts, so nothing to break. Make sure to keep the cylinder as vertical as possible. If it tips a little to the side gas can leak out.

Such a fun little piece. Simple and effective. Haven't had any real leak issues with it.

So first, this works pretty well to refill a standard backpacking iso-butane cannister (4oz, 7.75oz, etc.) from one of the taller cans used with some larger camping stoves. This is probably the smallest of the refill adapters you'll find on the market.Pros:It's small and very lightweight, which means it's great for backpackingIt's a fairly robust build, so it will lastIt comes with two additional o-ring gasketsOnce you achieve a good fit between the two cans, there do not appear to be any leakage issuesCons:It's small, so easily lost - especially on the trail, amidst leaf clutter, or into a firepit full of ashesIt comes with NO instructions, so check the seller's photos for some helpIt does not get secured between the cannisters in any way other than by friction and pressure. It will therefore easily get lost with just an inadvertent hand motion while you're using it. Make sure you're on a flat surface without much leaf litter. Better, do your refills on a workbench or using an old baking tray under everything to help contain small parts if they let pop off - this unit or one of the o-ringsThere is the danger of a LOT of leakage as you're positioning this valve between cans. With practice, you'll get better at minimizing that, but the amount of cold gas that sprays across your hand at first can be disconcerting. Do NOT use near flame.Once you start filling, the only way to tell if the process is complete is to listen closely to the hissing of gas moving through the valves. Will be difficult to tell in noisy or windy environments. Once the hissing stops, the pressure between the two cans has been roughly equalized, the empty can is full, or the filling can is now empty.Recommended if you can stand the limitations and cons above.

Perfect fit. Works as advertised.

I've save a ton of dough using this thing and it still works great, the butane canisters are far cheaper in the long run than buying more camp stove canisters. Just put the emptier camp canister in the freezer for 5 mins and it fills up the other lickety split. Money well spent

Works to allow Isobutane can to fill the long obsolete Colman powermax xcurssion lantern. The powermax fuel used an internal straw to feed from bottom of fuel can, allowing upright fuilling. This method needs to be filled upside down as pictured for best result. I cant believe an off the shelf solution exists. I know leds have surpassed this dimunitive lantern, but id rather use what I have. Esp. Since its lasted decades... try that led lantern...

I bought it for use ir with Thermacell but now work good

Muy necesario en campamentos
