Does REI keep any empty fuel canisters at the stores? I'm deciding between the 100g and 230g fuel canisters. I'd like an empty canister of each size to test what pots/cups/tools/etc I can nest and fit together. I know their diameters and heights, but it's still hard to tell what can be packed together without an actual canister.


hmmm, I'm betting they don't.

I think your best bet would be to just buy one of each and give them a try.

Nesting isn't all that it's cracked up to be.  Your can sits in the dirt, or on that plastic thingy with legs, and then goes into your pot or cup and bangs around unless you stuff something around it.

Hi @Eeqmcsq - Thanks for reaching out! While our stores do not specifically have empty fuel canisters for this use, you can reach out to your local REI and ask if they have any available. Additionally, while you are in a store, you can test the size and fit of canisters with different cook sets, which may be able to answer your questions. 

Hope you're able to find a setup that is just what you're looking for!

At REI, we believe time outside is fundamental to a life well lived.

Keeping a fuel canister in your cook pot is not necessarily the best idea since fuel canisters sit on the ground and you eat out of your pot. Also fuel canisters tend to rust around the base which can stain the pot.

REI Stores will generally have full canisters on the shelves although there have been shortages this year.

As to size the ~100g canisters are ~3.5 inches dia. will fit in all Toaks D95mm (3.75inch) series pots and the ~230g canisters are ~4.25 inches dia. and will fit in all Toaks D115mm (4.5inch) series pots.

The JetBoil Flash takes a 100g and the MiniMo takes a 230g

Most small pots are sized that way.

Generally 100g are better for solo use if you just heat water and a canister can last a week or more depending...The canisters are light enough that carrying a partial and a full one is not an undue burden if you want to used all the fuel and are prepared to pack out the empty...but sometimes only 230g are available so you have to go with those. 230g is probably better for two person use or if you actually "cook" on trail.

A 550ml pot is just big enough if you are only boiling water for one. I like the Toaks 650ml light for that since it provides a bit extra capacity and is slightly more weight efficient. If you are going to cook pasta type meals then a ~1L pot is a better choice. The Toaks 900ml 115mm is a popular choice but there are many alternatives.


Thanks everyone for the replies! Those are excellent points about dirt and rust on the canister getting into the pot. I hadn't thought about keeping the clean and dirty stuff separate. If I can keep the canister outside and separate from the pots, then its size and shape won't matter as much. Time for some more thinking and planning.
