Safe and reliable power comes in the form of the Firman Performance Series 4450/3550 W Generator. This generator uses a single-cylinder engine to operate and has a tank that can hold up to 5 gallons at once. Feel comfortable knowing that the generator will shut down when the oil gets too low, while the 4-in-1 Minder tracks data like the running hours, frequency and voltage. The frame features durable 1-inch steel tubing and the handle folds down for a compact set-up.
