Safety and controls

Bring the power wherever you go – from tailgate parties to camping trips, jobsites and beyond.

Runtime and fueling

This durable unit features an easy-to-use push button electric start for reliable, hassle-free ignitions with auto-choke (battery included), made for easy portability with an integrated handle and never flat wheels.

Portability detail

Want the option to reduce noise and fuel consumption – or to maximize power response?

Connection options

Plus, the intelligent LED display allows you to easily and accurately see power output and fuel consumption (gas), while onboard COsense® technology provides protection against hazardous carbon monoxide.

Ownership note

And because inverter generators utilize a different type of alternator to generate AC power, the result is a portable generator with reduced weight and size with ultra-clean power, capable of safely powering sensitive electronics and tools.

Additional manufacturer note

• Dual Fuel - Runs on Gasoline or Liquid Propane Fuel for your convenience.

Follow the manual exactly and record three ambient-temperature starts plus three heat-soaked restarts. Report attempts, elapsed time, start method, battery state, and any intervention.

Attempts per startStart timeAmbient temperatureStart method

Controlled conditions

Record the exact model, serial number, firmware, sample source, and test date before any measurement.
Log ambient temperature, humidity, elevation, wind, surface, and background sound for every test block.
Record instrument model, range, accuracy, and most recent calibration or verification date.
Repeat timing, starting, and sound measurements three times when conditions allow; publish every valid run.

Safety gate

Operate fuel-burning equipment outdoors only, far from occupied structures, openings, and ignition hazards, with working carbon-monoxide monitoring for personnel.

Testing is for qualified personnel using correctly rated load equipment and the manufacturer’s required grounding, bonding, clearance, and protective-device instructions.

Never connect a generator directly to building wiring or bypass overload, temperature, battery, GFCI, or carbon-monoxide shutdown protection.

Stop a run for unstable voltage or frequency, overheating, fuel or electrolyte leakage, abnormal sound, damaged wiring, or any manufacturer fault indication.

Badge rule: this product receives no “FMG Tested” label or score benefit until a real unit, instruments, conditions, valid runs, raw records, and limitations are documented under the public protocol.
