>>572536>But how long will it last( cooking lunch, dinner and maybe even breakfast) and how easy is it to find cartridges for this stove?Depends on, a regular size cartridge will last an hour and a half to two hours or so, usually lasts a good week if you keep it to boiling water mostly, if you cook like rice and pasta daily it is a different story. You can calculate 150g/h and cartridges are available in 100g, 230g and 450g, 230 is the standard.
I'm using a covea spider stove for my out needs and like it a lot, the flame pattern and stable stand help a lot if you need to simmer something,
Dunno about the availability of gas cans in Sweden in particular, but usually you can buy them easily in Europe, especially in popular hiking areas.
