Overview

Built for backcountry cooking where fuel availability can be uncertain, this multi-fuel stove is designed to run on a wide range of fuel types without changing jets. Its integrated cleaning needle and included multitool are intended to help keep the burner clear during use, while the control valve and vapor or liquid gas modes give you options for simmering, colder conditions, or shorter boil times. The kit includes the stove, pump, multitool, windscreen, heat reflector, stuff bag, lubricant, and user manual, making it a practical choice for extended trips and remote camps. Note that a fuel bottle is not included, and different fuel types should not be mixed in the same canister.

Pros

  • Built-in MAGIC cleaning needle helps clear the jet during use.

Considerations & Trade-offs

  • Fuel flexibility is a major advantage, but it also means you need to match the fuel mode to conditions and follow the instruction not to mix fuels in one canister.
  • The bottle is not included, so this is not a complete ready-to-use setup without the proper fuel container.
  • The stove is designed for both vapor gas and liquid gas use, which adds versatility, but it also means operation changes depending on temperature, boil-time needs, and canister pressure.
  • The included cleaning needle and multitool help with maintenance, but the stove still requires periodic attention to keep the burner clear.
