The Optimus Vega is a freestanding, lightweight gas stove that can be used not only with standard gas supply but also with an inverted cartridge for liquid gas combustion. It is best to turn the gas cartridge upside down only when the burner is already hot, as otherwise a flashback flame can occur. This simple trick with the liquid gas supply allows the stove to be used easily even in cold temperatures. The Optimus Vega has a very low center of gravity, making it suitable for use with large pots. In milder temperatures, the stove can be operated in an economy mode.
