Remember when you had clean and quiet portable power. The WEN Products 2,250 Watt Inverter Generator provides clean energy, free of voltage spikes and drops, without all the noise of a regular generator. This limits its invasiveness while camping, hunting, tailgating, and restoring backup power. The WEN Products 2250W Inverter Generator is also equipped with fuel shutoff. This feature turns off the flow of fuel, allowing for the generator to use up the remaining fuel from the carburetor before automatically shutting down. This helps fight the build-up and blockages caused by stagnant fuel inside of the carburetor, minimizing maintenance while prolonging the units lifespan. With power output designed to mirror a pure sine wave, this generator limits total harmonic distortion to under 0.3 percent at no load and under 1.2 percent at full load, making it safe to run laptops, cellphones, monitors, tablets and other sensitive electronics. The ultra-efficient one-gallon tank provides over 6 hours of half-load run time. The fully-packed panel comes equipped with two three-prong 120V 15A NEMA 5-20R receptacles and two 5V USB ports. Maximize fuel economy by engaging the eco-mode switch. This allows the generator's engine to automatically adjust its fuel consumption as items are plugged into and unplugged from the panel, preventing the unnecessary usage of gasoline. Easily link up two WEN Products inverter generators using a WEN Products 56421 Parallel Connection Kit (sold separately) in order to share wattage amongst multiple units. Low-oil and low-fuel automatic shutdown combine with the built-in overload protection and indicator lights to safeguard both your generator and your electronics from damage.
