That sounds impressive but the boiling points of water drops to around 89C @ 12,000 ft. It is much more difficult to raise the temperature of water at lower altitudes.

If we compare the Trangia mini setup and we want to boil the same amount of water compared to a 250ml or 8oz cartridge high efficiency butane/propane setup such as the Primus Eta Packlite system we would get the following;

An 8oz or 200 grams of propane/butane @ 100% efficiency will heat 26.5 ltres of water or 21 litres @ 80% (claimed by the manufacturer) to the boil.

The Total weight for the Primas Eta Packlite gas stove is 590gms (Eta Packlite) + 320 gms (fuel cannister + fuel) = 910 grams in total to boil 21 litres

The Trangia mini stove will require 306 grams of fuel @ 100% to boil 21 litres, typically the efficiency for the Trangia mini will be less than 50% (being generous) so the total fuel is 612 grams.

The Trangia weighs 320 grams and the trangia bottle weighs 112 grams giving a total 612 gms (fuel) + 112 gms (fuel bottle) + 330 gms (Stove and 0.9 litre pot and pan) = 1054 grams or 144 grams heavier (I have not included the wind shield weight)

The Trangia mini is also certainly limited to being a strictly one man affair compared to the Primus, which could conceivably be used for 2 man cooking. The Primus will also bring to boil a litre of water in less than 3 minutes. The Trangia will take at least 3-4 times longer.

The limitations and the greater weight for a alcohol stove become even more apparent when even more boiling capacity is required. The alcohol stove could simply not compete weight wise with the 500 ml 16oz propane/butane cartridge for the same heating capacity. The alcohol stove would end even heavier than a multifuel high performance expedition stove such as the Primus Omnifuel.
