- This is a nice gadget used to transfer fuel from one backpacking fuel canister to another. It's annoying to have a bunch of 1/4 or half-filled canisters lying around, but topping them off before a trip lets you reuse them and always go out with a full canister.
Thxs, I just bought one, but my Korean is not so good, 😎 Your video was perfect. I just emptied 3 bottles into two. I already have a Jetboil ‘crunchit’ for the old bottles. I may now buy bigger bottles (for cost savings) and transfer to my 100 gram bottles. Happy trails
Super helpful. No English instructions and was not certain what the vent valve was for.
Very cool video! First time I’ve seen this and it’s a must buy! Half used canisters everywhere, and now I have a solution!! Thank you Sir!
Very nifty little device there. Would be well worth weighing the valve and marking it so you don’t have to keep removing to re- weigh to get the accurate weight of the cartridge.
I usually just leave it on the large can and unthread the small can to weigh. You obviously have to remove one, so it’s easier to do it that way.
Great video! Thank you 🙏
This things great.. I sit the one cannister in hot water and let sit for 5 min and use an out of the freezer canister for the receiving cannister...promotes the molecules to "jump" from cannister to cannister better..
Excellent, precise review and tutorial.
Hey Mark, great vid! If you overfill by let's say 10g. Just put your stove burner on the filled can, put the whole thing on the scale, note the extra weight of the stove and open the stove valve while it's on the scale and you can watch the scale go down as the gas slowly comes out and close the stove valve at exactly 10g grams less. That way you don't have to release gas, unscrew, reweigh several times. You can do it all in one shot and it would be very precise. But perhaps too slow? Question, do you think you need the valve with the vent? Or will a vent less one do? I have to admit the quality of yours looks amazing.
cficecubevids yes that would work. I know it sounds silly, but I just feel safer weighing the can by itself and matching that number with the number on the can. Regarding the vent, I haven’t really used it at all yet, so I would feel good recommending the one without it
Mark B, thanks again for vid and thx for letting me know about the vent. Going to order one today.
Instead of losing gas by burning it or purging it, you can also return it to the original gas canister. All you need to do is to reverse the system: cool down the original supplying canister.
I may be the first to suggest: the donor cylinder be heated in hot water, and the receiving one in the freezer, as stated
Small thing --but very handy
I might be crazy but how is it possible to over fill a canister? It seems that they are just underfilling them at the factory.
The big canister is under the same pressure, it just has more volume in it. To me it should just stop filling when it's completely full. Am I crazy I'm my thinking here?
I have never done this before but looking into it now because I just hauled 2 half full canisters on a 4 day trip and I'm done with that crap.
BartD Yeah coming back with a half filled canister sucks. Can’t really do much with that, so I like topping them off with this before the next trip. If you overfill it and the canister gets warm, the bottom will pop out as a safety measure before potentially exploding.
p.s. I once put 120g into a can designed for 110g. Nothing happened, but I didn’t feel safe traveling with that so I let some gas out down to about 115g and it was fine. I’m sure they allow for some wiggle room for safety. Maybe.
@@OneclickOutside got ya. Yeah having an overfilled canister in any extra heat probably isn't too safe with no room for expansion. I think I'm going to have to experiment with this a little once I order the adapter.
I'd imagine in colder temps, it would be ok to overfill a bit if the canister is handled safer. Or if it were to be overfilled with strait isobutane instead of a propane mix. If I decide to break some stuff (hopefully not myself) testing this, I'll be sure to comment back lol.
Thanks for this video. Very informative. It's been quite a while since I wanted to add fuel to my canisters which are not completely empty. I was wondering if it's safe to fill additional gas to it. This answers my confusion. By the way, how long did you freeze your receiving canister with gas?
That’s what I do before every trip. I usually have cans that are half full so I top them off before each trip.
Regarding the freezer, I actually never do that anymore. I don’t find it necessary if both cans are room temperature.
@@OneclickOutside thank you for the information. Big thing!👌
I also immerse the donor can in warm water first. One concern I read about is that the cans contain liquid fuel but also vaporizing agents (gas to help evaporate the liquid fuel for upright stoves), and it is difficult to transfer that gas to the receiver can. So your refilled can, if using an upright stove, won't be able to let out all of the fuel. If you use a hose and put the can upside down, the problem is solved. Any comments? Does your field experience tell you that a refilled can is just as "useful"?
great review! one of the few I can tell was not paid for by any company. Thanks!
TJ Jones Thanks! Yes paid reviews are a big pet peeve of mine. Worse than useless in my opinion.
exactly
Very good, informative video. Thanks!
Great demo, thank you for posting it :)
You're welcome!
"You must be careful to not over fill it...oh wow its little higher" :D PANIC
Marcin Kaszubowski how much wiggle room? I don’t wanna find out!
Mark B LOL chillout buddy. Did you lower temp of one of those canisters. I red somewhere about it. And also about not equal amount of propane and butane when refill.
Marcin Kaszubowski I’ll usually put them in the freezer for just a couple minutes to make it easier. But I don’t think it’s always necessary. I do refill some of the larger 1 pound propane tanks and those definitely need chilled, but that’s a different process with a different adapter obviously.
@@OneclickOutside Is it necessary to place donor canister into warm water before transfer? Thanks for answer
Marcin Kaszubowski no don’t bother with that as long as it’s at room temperature
When I got one 90% filled can and another one with 10%, does this allow me to transfer the 10% into the 90% filled one? Maybe I misunderstood something, but isn’t the pressure higher when there is more gas inside? Where does the pressure come from, to get the gas into the can?
That would be tough. You can get about 5% of that in by making the receiving can cold and the other warm. But it gets to a point where you just can’t squeeze the last bit out.
@@OneclickOutside That's what I expected, thought maybe there is a trick, but I wondered where the pressure would come from. Are there systems which maybe make use of a pump or something? I don't want to buy those little cans over and over, would be nice if there was a real refillable multi-use can
I'm not aware of anything like that. If you typically use the 4oz cans, it's best to refill those from the 8oz or 16oz cans. It's very cost effective to just top it off before each trip. I usually end up with 30-50% remaining so it's easy to top off. If it's much below that I usually won't bother, or take it on a very short trip just to use it up completely.
@@OneclickOutside I was planning on doing that, but if I have no use for bigger cans with the little gas remaining. Should still be cheaper though, thank you!
At last someone like myself who knows what he is doing., just make sure you weigh the new can and write it on the bottom.
What do you write on them? I like the MSR cans since they list the net and gross weight, so there's no work involved. Jetboil lists the net weight but I think they are the same can. I always weight afterwards because it is definitely possible to overfill. Such a great tool...this saved all my canister stoves that would have been shelved otherwise!
@@OneclickOutside Weigh the new can, then write on the bottom the total weight, then you know how much gas to put in to bring it back up to the total weight
@@OneclickOutside Hi there, I have just put up an update video of my previous video, here's the link :-ruclips.net/video/ATkiGBsq-zE/видео.html
can you vent the donor can by opening the wire valve instead of the press valve?
I read somewhere that the button is used to let off gas from the donor can thus cooling it (via gas expansion), so it accepts more gas.
Can you vent via the button when both cans are screwed on? on just the donor?
You actually want to cool the receiving can, and warm the donor. Maybe the vent is supposed to cool the receiving can then? I'll have to play around with this and see what happens.
When the cans are connected, the vent button works but I'm not sure which can it is actually venting.
When only one can is connected, you can vent by opening the valve or pushing the button if you accidentally over-filled. The button is easier since I find liquid sort of splashing out when using the twist valve and it's not as accurate compared to short bursts with the button. Always keep the can upright either way.
After using this so often, I usually get it right around 205-210g on the first short without any effort and just listening to the gas flowing. I usually don't bother filling to exactly 100%.
Nice review, thank-you
Mark Bishop you're welcome!
MSR cans are 110g I believe. And jetboil is 100g
Axletine correct, not sure why they fill them differently. Same can/manufacturer from Korea I believe
Mark that’s weird... so you mean one isn’t SLIGHTLY larger? They are the same can?
Axletine same can, and I believe they’re the same fuel mixture. 80% isobutane 20% propane.
Axletine the gas has that mass, not the fuel + can. He’s explaining how much the gas + can weighs.
It's been 3.5 years since you made this video. Are you still using the valve or did it FAIL or did you lose it B4 you ever broke even?
AZ Claimjumper Still using it before every trip without any issues! In fact, I just got back from another trip where I used a topped-off canister as usual. It’s really nice going out with a completely full canister for every trip without having to buy a new one each time.
@@OneclickOutside Thanks for adding your experience with the valve over a period of time. Being able to begin a trip with a full or near full 4 oz canister is more of a selling point than the possible cost-savings over a really long period of time. I'm surprised there aren't less expensive competitive products on the market by now. $40.00 seems exorbitant.
I'm using a Soto Windmaster. Which brand stove have you been using?
@@azclaimjumper "I'm surprised there aren't less expensive competitive products on the market by now. $40.00 seems exorbitant ". Perhaps. But by all accounts it is well-made and works perfectly.
As John Ruskin said: "There is hardly anything in the world that some man cannot make a little worse and sell a little cheaper, and the people who consider price only are this man's lawful prey.
"It's unwise to pay too much, but it's worse to pay too little. When you pay too much, you lose a little money - that is all. When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing it was bought to do.
"The common law of business balance prohibits paying a little and getting a lot - it can't be done. If you deal with the lowest bidder, it is well to add something for the risk you run, and if you do that you will have enough to pay for something better."
@@rogerharris3951 Which stove do you have?
Does the orientation of the device matter? Like do you need to "gas saver" be right side up or does it not matter?
That’s a good question. I’m not sure. I just always put it on the bottom can with the logo/writing facing upright which works.
It doesn't make a difference since the gas can move in both directions through the valve. However, if you read carefully the product description on Amazon it says: "2. Tighten the gas container you want to use based on the printing direction, and assemble the gas container with the remaining amount on the upper part." It is not very clear, but one can understand that when assembled, the Gas Saver must be in an "upright position" in a way you can read the printing on it.
I believe a canister has a mixture of liquid and gas with the mix dependent on pressure. By placing the donor canister on top you transfer liquid rather than gas.
woah woah woah, that g vent
is wasting a ton of fuel tho why wouldn't you just flip the adapter and pour it back into the bigger can???
I never use the vent. Maybe a gimmick. I simply top off before each trip. Never fails.
@@OneclickOutside nice are you saving money as well? I’m trying to research how I can also fill with a mix of butane with propane to save some cash. Ebay has propane tank to canister adapters kinda neat if it works.
where do you buy the large canisters of fuel? Having a hard time finding some.
I'm lucky even to find the 8oz cans in town. Everyone just stocks 4oz. So I got lucky and found these 16oz cans at bikewagon.com. They were on sale for $9 with cheap $2 shipping. Many stores won't even ship these so you just have to look around. Stick with the MSR or Jetboil if you can - they're a 80/20 mix of isobutane/propane so they work pretty well in the cold. Off brand stuff you get at walmart is likely much lower in propane, if any at all.
And remember to be safe by transferring the same mix of gas from one to the other (80/20 > 80/20). So Jetboil to Jetboil, MSR to MSR, etc. I've transferred Jetboil to MSR cans because I believe it's the same mix. I do think these cans are all made by the same place, but I don't want to risk it.
Thanks Mark. I did find some on Ebay, So I ordered 3. More than I wanted to pay but shipping was free.
Good deal! I was never able to find them on ebay. Paying a little extra will be worth the convenience of topping off smaller cans. You don't necessarily need larger cans, but it does make more sense. Sometimes I'll just use half empty small cans to top off another.
4 years later I have a great source! A Sportsmans Warehouse opened a couple years ago. They sell all 3 sizes in at least 4 brands. Jackpot!
I don't read Korean either. Good video
You want to completely blead the tank, freeze and then fill.
Northwest Elite I never had to do that, hope I never need to. I like topping them off before each trip.
@@OneclickOutside Just don't put a full canister in the microwave.
Is the new R2 version better than the R1 shown in this video?
Battlem0nk I haven’t tried the new one. But it looks nice and they say they improved the durability. However I never had any issues with the old one so far as it seems solid; nothing really on it that would break under normal use.
@@OneclickOutside Think they just added brass threads to reduce wear. I ordered one to try out. It's been on amazon since 2018 but no reviews. Gave it a shot.
How to fill without using a SCALE?
You could just let it go until you stop hearing the gas flow, but you do risk over filling it. I’ve done that a few times myself.
@@OneclickOutside Not seeing a big problem with 'overfilling' it unless you keep it in a hot place.
If you do not vent any of the air then that leaves room for expansion.
What happened when you overfilled one?
@@zolar1nonassumpsit219 Yes it’s just a safety precaution for instance traveling and having it in a hot car. I went maybe 4 grams over and just vented it to be safe.
$29.95 on Sale on eBay as of today. This is the lowest price ever. And quite likely to be even lower AFTER New Years'.
REI has the same for 10 bucks
Never had to use freezer
cosgrove notts always a bonus
Why not cool the big canister and move the fuel back?
bobfre1 if you want to fill the big canister, sure. But I always fill the small canisters from the big one. (Warm=donor canister. Cold=receiving canister)
Yeah... I understand the process. I just don't get why you would waste the 7g by burning it off or venting it rather than putting it back in the big can. I haven't checked, but I'll bet you can boil a cup of water with 7g -- why throw that away???
bobfre1 i'm not throwing any away or burning it off. If you're referring to me using the valve in this video, it was just to show the function of the valve and how I don't think it's really necessary since it wastes it like you said. All other times I simply let it flow until I do not hear it anymore, and it always gets me close enough to the max
Then what the heck were you talking about at 3:45?
At 4:05, aren't you just blowing off gas because you over filled it??? Why not put it back in the big can?
We don't use grams in 'Murica' eh.
Nelson M. LOL, no we don't. But ounces are definitely not accurate enough when dealing with such small amounts of fuel. Hell, there's only 4 ounces total in the entire small can to start with.
Everyone in the engineering, or scientific, or medical fields do. Soda is sold in liter bottles, and the automotive fasteners are in millimeters. Even 3/4" plywood isn't really 3/4" thick -- it's 18mm. The metrification of Merica is happening whether you recognize it or not.
why mess around just buy a 20lb tank of butane gas company's sell them
That would be easy and less expensive but butane doesn't work well in the cold, about 35°F or so. A fine summer option though. I just don't get out much when it's warm.
Not to be confused with 20lb propane tanks. Also cheap, but EXTREMELY DANGEROUS. Never fill these backpacking canisters with straight propane. Their thin walls will not support the high internal pressure.
