Description

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.

I have the 2000w model and it works flawlessly, however it cannot run the ac, so I have upgraded to the 3800w model. You get some tools and an excellent funnel to make filling oil easy. You have to undo engine securing bolts before running it, and the paper that told you that was tucked in with the rest of the documentation and I can see someone missing it and trying to start the genny with the bolts still on. So, the issue that I did have. Filled with gas, filled with oil, put in the magnetic oil top that i had from my 2000w, turned to on and pushed button. Its cranking!!! But, no cigar. No matter what i did it would not start. I went through all the troubleshooting and the decided to check spark plug. Guess what, it was completely off, popped it back on and it started on the first pull!!! Yay!!! Now I just need to recharge the battery and we are good to go. The generator is quiet, and I am gona be a happy camper! It is pretty heavy, however the wheels and the handle make it very convenient to wheel around. Issue - the genny would not stay running.
