Trangia Pre-Heater Most know that Trangia-type alcohol burners become problematic in cold temps. This device is designed to allow use of alcohol Trangia burners in low temps. How low is unknown; I reckon warming the entire stove and fuel bottle inside cold-weather garments will help a lot.
This gizmo attaches (nests) on bottom of Trangia stove (and some compatible clones) in order to pre-heat the Trangia stove and its' alcohol fuel in cold temps. Pull it away from the stove into second "groove" on stove to deploy.
Leave it home in warm weather and take it with you if cold temps expected.
Note carefully that the genuine Trangia burner has "grooves" in its' sides to accommodate this device.
Some perfectly good clones might lack the necessary "grooves"; other perfectly good clones have them.
From many vids on YouTube, this contraption works well.
Seems like a useful device to me, but no Expert.
Shop around for price, as always.
ETA: After trying out this device in recent low temps, I'm a fan.
Suggestions:
1) Shop around. Device by itself is less expensive than buying other devices along with it. AFAIK, Trangia main site is cheapest place I've found so far. Suggestions welcomed.
2) Ensure your "Trangia" type stove has the ridges around outer case needed to use this device; some clones lack the ridges.
FWIW, I'll not buy any Trangia type alcohol burner that is incompatible with this device. YMMV.
