Remember when you had clean and quiet portable power? The WEN® 4,000-watt inverter generator provides clean energy, free of voltage spikes and drops for safe use with laptops, phones, and other sensitive electronics. 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 sensitive electronics. Our ultra-efficient 1.85-gallon tank provides over seven hours of half-load run time. 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 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. And because it's a WEN® product, your open frame inverter generator comes backed by a two-year warranty, a nationwide network of skilled service technicians, and a friendly customer help line, all to make sure you remember WEN®.

  • Generates clean power to safely operate sensitive electronics such as phones, tablets, TVs, and computers
  • Parallel-ready panel allows you to connect any 2 WEN inverter generators for increased wattage output
  • 212cc 4-stroke engine produces 4,000 surge watts and 3,500 rated watts

  • Includes two 120V NEMA 5-20R receptacles, two 5V USB ports, one 120V RV-ready TT-30R receptacle, and a two-year warranty
