AQVAcalda is a portable, compact, solid metal flask/mug, butane gas powered, with catalytic combustion, all-embedded; easy, safe & always ready-to-use, with extended boiling feature.

It is a combination of reused power camping canasta & a thermos / falsk & i really like this portable flask coz users can use it everywhere and in countless occasion in addition users can boil anything just with a click of button.
