StormBreaker ignites instantly without heating, whether you use gas or liquid fuel. Switching fuel from liquid to gas is easy thanks to the dual-function nozzle. The same nozzle works for both types of fuel! Inverted gas container for use in colder temperatures. Generator-heated gas does not depend on the pressure from the gas cylinder to obtain a constant flow and combustion. The package includes Soto's medium-sized fuel bottle (700 ml) for liquid fuel.
