Then I have bought a very small one with fire starter... It's very light, not very robust, but certainly good enough for many purpose. Don't expect it to take a big pot, however.
If I need to use a big pot, I will go for my white gas stove (白電油爐) which could also be used with gas. Therefore, the smaller gas stove is reserved for trips with hiking.
For that purpose, I wanted something lighter, and maybe even more solid and stable. So, titanium stove would fit the bill well. Below you could see their weight, the original with a fire starter is already very small and light weight. But then the titanium one is even smaller and a few times lighter!
The energy output is very respectable too, the ultimate portable gas stove.
