Hi all, new guy here was wondering if someone could help me out, I got a can of Coleman c300 the one that apparently works at -27, Iíve used it three weekends in a row, mainly for coffees at overnighterís between me and my son, a few packets of super noodles etc but not a Sunday dinner lol it looks like the gas is going done already due to a low and slow burn rate, with a different can on it fires like a plane taking off a runway, having NOT used this before, should it only last this long? Iíve read it should be a two hour burn rate but Iíve definetly nowhere near that
You can calculate the amount of gas remaining by weight if you have suitable scales. The C300 Extreme weighs in at 351g full and contains 230g of gas, therefore the cannister when empty weighs 121g. Current weight minus 121g = gas remaining.
There are too many variables in actual camping use for manufacturer's figures, usually obtained under controlled conditions, to be reliable or relevant. For instance, water will boil quicker and with less energy consumed in a kettle or pan with a lid on than in an open pan. Ambient temperature and wind can also have an effect.
You don't say what stove you are using but in my experience this can also have an effect.
I have a cheap generic chinese made burner bought from Wilko which sounds like a jet engine when on full chat and which with some loss in performance will exhaust the gas of any cannister that I have tried.
On the other hand I have a GoGas (GoSystems) burner, better design and quality of engineering where the flame fails whilst there is still gas left in the cannister.
------------- Never argue with fools........They drag you down to their level, then beat you with experience.
I have those kitchen scales so I will try that, I use the Coleman fyrestorm I think itís called, it has the built in wind deflector with a pot and silicon lid, it just didnít sound overly powerful at the weekend there, I weighed the whole tin on the scales and said 217g
The type of gas can you have contains a mixture of butane and propane, in the cold morning temperatures we've had recently the propane will distil off and fuel the stove while the more sluggish butane will remain. So although your gas can still feels and weighs half full it will burn very slowly on a cold morning.
Get a new can to make that cup of tea on a cold morning but save the half full sluggish cans for doing lunch or dinner on a hot summers day.
Spot on thank you for the tip! Iíve the adaptor for the tins of butane you get in multipacks room but when theyíre running it seems like it pulses a bit compared to the screw threaded cans, or maybe I am doing something wrong lol as long as I get a coffee Iím happy I suppose lol
