The WEN GN400i is a 4,000-watt surge / 3,500-watt running open-frame inverter generator with a 212cc OHV engine, a 1.85-gallon tank and a built-in 120V TT-30R outlet for RV hookups. It produces clean power (under 0.3% THD at no load, under 1.2% at full load) so laptops and phones can run safely, and it weighs 66.1 lbs with a pull-cord start. It is a budget inverter rather than a quiet closed-frame unit, so expect more noise than a suitcase generator. The latest best price sits near the low end of its recent range, which makes it a strong value among 3,500-watt inverter generators.

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. Our 212cc 4-stroke OHV engine produces up to 4000 surge watts and 3500 rated watts of power. 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 7 hours of half-load run time. The fully-packed panel comes equipped with two three-prong 120V NEMA 5-20R receptacles, two 5V USB ports, and one 120V RV-ready TT-30R receptacle. 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 its 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.
