In Diois, France. So nice to wake up with the birds next to me again.
How do you cook your coffee when camping?
Nice, this is a stove that uses these slim butane canisters, right? I buy these canisters to refill my screw mount ones, they cost like a fifth at the Indian supermarket. Works fine if not freezing.
A special adapter from Amazon, like $20.
Be sure to refill by weight. Buy a full screw top canister and weigh it with a kitchen scale, note the weight in grams, write it on the can and in your phone.
Then later, when it’s empty, put it in the freezer for several minutes, pull it out and refill it with the other canister, but only fill it to the weight it was originally at. It will gladly take more gas, but there will be less headroom or no headroom, and the canister has a high chance of exploding.
The Internet will tell you not to do it, and how unsafe it is, how the valves aren’t meant for that many uses, and it’s definitely gonna explode etc etc. But if you do it smart, you’re fine. And don’t reuse the same screw canister many many times, you’re already saving money, reuse it a few times then recycle it and start over.
Edit: this is the one I bought, it’ll do the trick. https://a.co/d/eHJDQGL
Also NEVER EVER EVER refill them with any amount of propane! Yes the normal canisters come with a percent of propane in them to help in cold weather. But getting the partial pressure mixture right is almost impossible at home, and propane will definitely make your canister explode. It’s vapor pressure is too high. That’s why the pure butane canisters are so thin, and the green pure propane canisters are so thick and heavy, because they need to be to hold back the pressure.
I am using a simpler one, like this. But yours looks pretty cool, you can do screw mount to screw mount with it too, right?
Wow, thank you for the very thorough write-up!
I was wondering how you’d get it past the point where it’s just equal pressure to the other cannister; I assume that’s the reason for freezing the one being refilled, and I’m guessing the cannister that’s being refilled needs to be a smaller than the one that it’s refilling from?
