soooo you've got a lot of partially filled iso-butane fuel canisters.......

[mtwarden]

yeah me too, pain in the a$$

enter the gadget that lets you fill partially filled canisters from other partially filled canisters- letting you have fully filled (or otherwise) canisters

simply put the canister you want to fill in the freezer for 20-30 minutes, pick which canister is going donate fuel and voila!

this is just a sample of the ones I have (have a bunch of 8 oz ones too)

ready to go, turn the petcock and fill

gadget can be found here (probably elsewhere too)

Dang, I just normally shoot them.....

Thanks for the heads up!

And when you add all that last little bit of gas into one canister it likely isn't anywhere near the original mix and likely won't do well in cold weather so keep that in mind.

Seems pretty handy!

Dumb question: What does putting the canister in the freezer do?

Allows the gases to cool. The temperature difference between the canisters is what causes the transfer from one to the other.

I went from about 25 partially filled canisters (4 and 8 oz ones) to 7

also if you notice that the larger canisters (8 & 16 oz) are cheaper per ounce than the small 4 oz ones, buy a big one and fill from it

There was a discussion on this a couple years back, or maybe a podcast? I think I remember there's a possibility of overfilling and creating a dangerous situation, so you need to weigh a full container of the exact same make/model so you know how full to let it get (fill to the same weight)

I want to say there was a photo of one looking swelled up like a grenade ready to go off, but maybe that was just what I'm picturing...

Still have one of these in one of my gear tubs, haven't used it though.

Be careful with this everyone!! Do it outside. I’ve been to some explosions where people were making butane hash oil and butane gas filled the room without warning. It’s very very dangerous with butane, but I realize these aren’t the same thing either.

I could be way off on this, but definitely is worth the precaution of doing this outdoors.

Playing with pressurized canisters of highly flammable gases seems like a bad idea all the way around. I'll just carry two canisters and switch them out. Seems pretty easy and not something to risk life or limb over.

I had a friend loose some eyebrows with a canister/stove explode in his face. Very dangerous.

Good luck kids!!

Well Ill be. Ive always packed two canisters with me because Im always wanting to use up that last little bit from that partially empty one.

Thanks for posting.

Following along this thread, looks intriguing just a little concerned about possible safety issues. But like anything I’m sure if done right there’s no worries...

 

[Dos Perros]

They're like $5.

 

[kentuckybowman]

maybe you could use the partially filled canisters as bear deterrent. when the bear gets to you just shove it in his mouth and right when he bites down on it light a cigarette lighter. kind of like the end of the first jaws movie.

 

[Sccritterkiller]

I just save the partial ones for duck season and use them then...I like hot coffee during duck season...Carrying a couple cans in my blind bag is no big deal.

 

[BRTreedogs]

They're like $5.

I can't even find any locally

 

[Rokbar]

I've never used these type canisters before but do plan on getting a windburner to use. Do they not have an pressure relief on the can like the green ones for lantern's?

Where are you located? Scheels and REI have plenty here in KC.

My lady found a couple of the bigger ones but the 3 or 4 stores we normally get the 100 gram ones at have been out since the rona rush.
Mountain house is back on shelves.
I have a few and can surely get thru my season but its starting to make me a little nervous.
Most of the places online that have them in stock and will ship have double or triple the price.
