Remember when you kept the lights on? Keep your family safe during power outages and natural disasters with the WEN 4500-Watt RV and Transfer-Switch Ready Inverter Generator. The onboard inverter provides quieter and cleaner energy, free of voltage spikes and drops. Our 224cc 4-stroke OHV engine produces up to 4500 surge watts and 3650 rated watts of power on gasoline, or 4500 surge watts and 3285 running watts on propane. The keyless electric start lets you turn on your generator with the simple push of a button, and features an included recoil pull starter as backup. The WEN Watchdog CO Shutdown Sensor helps protect both you and your family by automatically turning off the generator if dangerous levels of carbon monoxide are detected. Designed to mirror a pure sine wave, this unit limits total harmonic distortion to under 0.5 percent at no load and under 1 percent at full load, making it safe to run laptops, cellphones, monitors, tablets and other sensitive electronics. Our ultra-efficient engine paired with our extra-large 4-gallon gas tank provides up to 12 hours of half-load run time, or get the same half-load runtime from a 20-pound LPG tank. The fully-packed panel comes equipped with two three-prong 120V NEMA 5-20R receptacles, two 5V USB ports, one 120V transfer-switch-ready NEMA L5-30R twist lock receptacle, and one 120V RV-ready TT-30R receptacle. Maximize fuel economy and runtime 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, minimizing noise and fuel usage whenever possible. The lightweight body weighs 30% less than a traditional 4500-watt generator, while the included wheel and handle kit makes for easy transport and storage between uses. The panel’s data meter monitors the voltage, frequency, total runtime, and session runtime. Low-oil shutdown, combined with the built-in overload protection and indicator lights, safeguard both your generator and your electronics from damage. Standard SAE quick-connectors make connecting and disconnecting the battery faster and easier than ever. And because it’s a WEN product, your dual fuel inverter generator comes backed by a three-year limited warranty, a nationwide network of skilled service technicians, and a friendly customer help line, all to make sure you remember WEN.
