Does the Coffee plunger require this? Would be great to have anyway!
I was thinking about internal dimensions of the bushbuck pot, to see if their plunger width would work in the Campster cooker

The gas canister can really affect what the cooking time is, I had one gas canister that was garbage where the other one of the pair brought at the same time was doing the mahi in a 1/3rd of the time.

So for facts and figures, my campmaster arrived yesterday (couldn't help myself) and with a Kovea 70/30 can up it's bum it did from 20degC to boiling in almost 4 mins flat. 500ml from the cup measure.

So is it the butane mix proportions or the cannister pressure? Do we get what we pay for when buying gas cylinders? I would be interested to know if the more expensive cans are actually better value? I am sure some knowledgeable member here will know the answer.
Many thanks Ruger7mm

Well, if the can has more gas pressure than the appliance needs the regulator reduces the pressure output to what the appliance requires.

Gas ratio is somewhat critical though - propane burns a lot hotter and is better in colder temperatures as it has a much lower boiling point than butane (-45 rather than butane's 0) which means that as you drop below zero the "standard" iso-butane/propane camping cans aren't much chop. The reason these mixes are what you normally get as the standard is a little bit of safety among other things, as butane is a lot cleaner and less likely to create carbon monoxide if used in an enclosed space.

Some more technical places that sell more hard core gear often have 50/50 ratio cans which burn hotter but if you're planning on cooking in areas where the temp is much below freezing you're better to go with a liquid fuel stove otherwise the contents of your cylinder will separate into liquified butane which won't evaporate and be burned easily and the still-gas-state propane which burns as per normal.

The actual cost of the can may or may not be a factor in efficiency, as different shops often run different prices and it's sometimes luck of the draw in what you get. The mix is critical to performance, 70% butane 30% propane is the usual mix encountered but 50/50 burns hotter.

Will be the go-to for road trips.

Full refund processed. Just needed a couple of photos and an online upload, process is pretty seamless.

Replacement order has since arrived. They're not too bad. I'd probably just use these for a cup of tea or trips to the beach etc...

Still prefer the WW2 German mess kits for multi-day trips

I have the jetboil trivet modified to use on the campmaster. I used a chainsaw file to cut notches for the igniter and bent out the tabs so it sat better.

Yeah, wind is the big drawback with the BRS, doesnt bother me too much as i mostly use huts, also another thing to consider is finding level and firm ground, as its easy to topple over if your not careful, although these issues present with virtually all ultralight stoves that fit on top of the canister with the exception of jetboil designs. You can carry those foil windshields that do a reasonable job and is something I would recommend.
The jetboil comes with plastic supports to clip under the canister to provide extra support and works fairly well out in the open where you are exposed to wind.

Canister pressure can make a slight difference, but its more to do with the mixing ratio of the butane and affects how much propane boils off in the canister first. Propane has a lower boiling point, so gives you more pressure.
Those canisters are not strong enough to withstand a high propane content, so a blend of both butane and propane lowers the combined pressure.
The real cheap canisters may only contain butane, but not ultra common, if it has a propane mix, you will be better off in cold weather, but remember in sub zero conditions the propane will boil off first and the stoves performance will drop to virtually nothing.
Most decent brands will have a 75% butane to 25% propane mix, so buy the cheapest you find with the highest propane in the mix, they all perform just as good from my experience, it all comes down to the propane content.
The campmaster ones come in a slightly larger size than 110g too, might be 120 or 130 grams from memory.
I use a cheap refill adapter from ebay to refill mine from those cheap bayonet canisters.

You can usually find those cheap butane canisters at mitre 10 or the warehouse for only $6 or so in a pack of 5.
The cheap ones are butane only, but slightly more expensive brands have the propane mixes, in summer I dont care, I just go with the butane ones and is only 75cents to fill a 110g canister!
Its quite safe and nearly impossible to overfill them, the only way to overfill them is to put in the freezer after the first fill and inject more gas into it.
Weigh an empty one with scales and measure the difference in weight.
The price of those kovea canisters and other similar brands in the outdoor shops are selling for ridiculous money these days, $12 for 110 grams? Those things used to be only $5 not that long ago.

I've never seen a 75/25 brew but I guess they are out there - I have found a campmaster 80/20 cylinder and in the interests of science I'll line up the same test I did with the Kovea 70/30 can. That will tell us what the difference in performance is with the change in mix - both are near new cans. For memory of the reference, the Kovea 70/30 went from 20degC to boiling in for minutes and 6 seconds. I would expect the 80/20 to be between 4:30 and 5 mins from past experience. The 50/50 expensive brews are noticeably quicker.

For really cold days, I've been known to piss on a patch of ground and bury the can in it prior to cooking - giving the can a really good shake up first and even leaving it inside my top layer to warm up. Anything to boil the butane fraction again and allow it to burn - it will just sit on the bottom of the can and do f-all if it's liquid!

Burying the can is actually a good move for stability purposes as well - doesn't work in rocky areas though.

Its quite interesting looking at the various mixes.
Ive just been looking at some of the canisters ive got here and realised it doesnt even say the mix ratios on any of them.
A couple of my koveas just say butane/propane, and the rest say isobutane/propane, then my primus powergas is marked 4 seasons propane/butane/isobutane.
jetboil has always had isobutane in the mix and performs better than butane as it has a lower boiling point.
Going by what you are saying, Kovea may have increased their propane ratios to 30%, thats got to be a good thing.
These koveas are still advertises here at 75/25, but that info might be out of date now.

My AliExpress pot stand arrived today, It fits really well and actually locks onto the CampMaster burner quite well. When folded up it fits snuggly inside the matching pot. It was $17.59 inc post & GST and arrived in just 6 days (a new record from Ali)
