Remember when you had clean and quiet portable power? The WEN 2500-Watt Dual Fuel Inverter Generator provides clean energy, free of voltage spikes and drops, without all the noise of a regular generator. Produce up to 2500 surge watts and 2000 running watts on gasoline or 2250 surge watts and 1800 running watts on propane. Our 80cc 4-stroke OHV engine operates at an extremely quiet 52 decibels at no load, quieter than a window air conditioner or the average conversation. This limits its invasiveness while camping, hunting, tailgating, and restoring backup power. Our unique Auto Fuel Selection Technology automatically switches between propane and gasoline for longer run times with limited hassle. The WEN 2500W Dual Fuel 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 unit’s 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 1.2-gallon tank provides up to 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. Need more energy? Easily link up two WEN inverter generators using a WEN 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. Whether you’re tailgating, camping, or preparing for natural disasters, it’s always better with a WEN portable generator. Remember when you had reliable power? Remember WEN.
