Any liquified petroleum gas is substantially reduced in pressure by low temperature
. Butane is more affected than propane (below 0°C or 30°F butane has no pressure at all), and the smaller the container the worse the problem... but any fuel container held right beside the burner has the advantage of being heated as a side effect of operating the burner. Butane and butane-rich propane/butane mixes are commonly used both for backpacking in North America and for RVs in Europe, so it is obviously workable in common camping conditions.
The adiabatic (ideal or maximum) flame temperatures
for burning propane or butane in air are essentially the same. Common portable single-burner butane stoves (such as baglo's) simply tend to have larger burners than common propane camping stoves, so more heat is produced.
