I bought this compact camping stove in the Alps last summer and for 29 euros I couldn’t be happier.
It weighs 84g, Has a max Power output of 3kW and has an working gas usage rate of between 80g and 240g per hour.
It is really quick at boiling water. I haven’t timed exactly how long it takes but I am always surprised how soon I can have a brew ready.
Do not expect it to be able to support a large pan as it is rather unstable as it just screws straight into the top of the gas canister and the pan supports are not that large. (the compromise between weight and capacity)
All in all I am very happy with it.
