Other missed detail: with these foldable stoves* the pot is too close of the flames, for Trangia B25 (or copycat, knockoff) the height should be 25 - 38mm, see in the dozens of tests made by Hiram Cook, Paleo HikerMD and others. * The height in the foldable stove is optimized for solid fuel tablets.
4:50 - Trangia burner need at least 1" between the flames holes and the pot base, will boil water faster with 1.5". See Hiram Cook, ColoradoCamper, PaleoHikerMD tests with different heights.
