Description

Remember when you had clean and quiet portable power? The WEN 3,800 Watt Inverter Generator produces clean energy free of voltage spikes and drops without making all of the noise of a regular generator. Generate up to 3800 surge watts and 3400 rated watts of power. Our 212cc 4-stroke air-cooled OHV engine operates at an extremely quiet 57 decibels at quarter load, about as quiet as a window air conditioner or the average conversation. This limits its invasiveness while hunting, camping, tailgating and restoring back-up power. The WEN 3800W Inverter Generator is also equipped with fuel shutoff. This feature turns off the flow of fuel, allowing 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. 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 enough to run laptops, cellphones, monitors, tablets and other vulnerable electronics. The lightweight design along with the built-in wheels and folding handle make for easy portability while the ultra-efficient 2.2-gallon tank provides over 8.5 hours of half-load run time. Our fully- packed panel comes equipped with two 3-prong 120V standard household receptacles, one AC 120V 30A NEMA TT-30R receptacle, one 12V DC receptacle, two 5V USB ports and an easy-to-read digital fuel and load display. Maximize fuel economy by engaging the Eco-Mode switch. This feature allows the generator's engine to automatically adjust its fuel consumption as items are plugged into and unplugged from the panel, preventing the usage of unnecessary gasoline. The oil access cover makes for easy oil changes. Need more energy? Easily link up two WEN inverter generators using a WEN GNA50i 50-Amp 6000-Watt Parallel Connection Kit (sold separately) in order to share wattage between multiple units. Low-oil and low-fuel automatic shutdown, indication lights, and overload protection safeguard both your generator and your electronics from damage. The included spark arrestor allows for legal use in national parks and campgrounds. And because this is a WEN Product, your inverter generator comes backed by a 2-year warranty, a nationwide network of skilled service technicians and a friendly customer helpline. Remember when your generator powered your electronics safely and quietly? Remember WEN.

    • 3 year Review. It's a great unit
Size: 3800W + Electric Start
The media could not be loaded. I've had my WEN 3800 Inverter Generator with Electric Start for 3 years now, and it continues to impress me. It starts up easily every time, runs reliably, and powers everything I need. It’s a bit on the heavy side, but the wheels and handle make it manageable. I get around 10 hours of runtime on a full tank using eco mode, which is great for camping, backup power, or job site use. Super quiet for the power it puts out. Overall, highly recommend if you're looking for a dependable mid-size inverter generator. ... show more

    • Outstanding generator
Size: 6800W Dual Fuel + 240V + Electric Start
I normally would not do a review on a generator, but I'll seriously impressed with this particular model now. I already have another WEN generator from when I'm camping but I was really wanting one for the house and this delivered. I ran this for 3 days straight when we had a big blackout due to very severe storm running off my 100 lb propane tank and this thing ran the entire time without issues. After the event was over, I of course changed the oil and was pleased to see it was still in pretty decent shape. I mainly bought this so I could charge my EV'S, especially my F-150 lightning during the daytime when noise wouldn't be a problem and then run the house off the F-150 Lightning during the evenings since it's silent and this worked very well. Honestly, I think my neighbors would have been fine even with this running in the evening because it was not all that loud. One other thing I did like about this is it's an inverter. I have a gigantic harbor freight generator as well but it puts out square wave versus sine wave. So all my sensitive electronics greatly complain about dirty power especially my battery backups. With this generator in use all my battery backups and equipment that reports back electrical quality were just fine. They didn't know the difference between power from this generator and power from the electric company. The electric start is also very nice. If I'm being honest. My other generators are the pool kind and while they typically start up with a few pools, it's really nice just to press a button and watch this thing start up. I haven't used gas yet and probably never will since I have a giant propane tank and it's way more convenient, but that also limits the maximum amount of power. I will be able to get out of this as gas is able to generate more power than propane but this puts out enough wattage for my needs running on propane. In regards to portability it is heavy. I'm not going to lie but it does have wheels and it has a really nice handle that is sufficient to be able to support the weight of this. But if you think you're going to lug this up a bunch of steps by yourself, you're going to really want to reconsider that and get someone to help you. In terms of fuel consumption, especially compared to my dual fuel harbor freight model, this did better. Not sure why of course, but I used way less propane running this at full capacity than I did with that harbor freight. Final summary, it's great. I did see a couple reviews including one that showed this caught on fire for them. Not sure what happened in that case but it did cause me hesitation. But I'm pleased the report that giving this generator ran for legit 3-day straight without stopping without bogging down and without any issue to me. It's an excellent generator. ... show more

    • Great little unit
Size: 3800W + Electric Start
I have the very large though mobile Generac units to run well pumps at the farm, etc. For the barn, I’d like something whisper quiet so I can play a stereo connected to Bose outdoor speakers. When I first got it, I thought what a tiny little cube. It is a tiny little cube comparatively but is it ever a reliable little workhorse. Ergonomically the fold down handle is wonderful. It’s not one of the split wheelbarrow type handles and it folds fully back into the cube. And the wheels on the back make it easy enough for a person of any size to pull it up on a trailer bed or even across hay covered barn floor. Every single time I’ve pulled that cord, it starts on the first pull. Rotate the primer knob to Start position, pull and Whoala! It runs and runs and runs for hours. No 93 octane required. I had to laugh when my Chinese unit was needed to jump start my Genera’s dead battery, started in the first pull, did its job and the well pump worked. The only thing I’d tweak in engineering is the whisper. It’s whisper is kinda like a 6 year old grand daughter in a movie theater that everyone behind you and in front of you hear. Don’t get me wrong. It’s quieter than a larger generator but it is no floor fan. 55db is questionable with one Nakakixhi amp plugged in yet wuiet enough that you can sit with a small glass of bourbon in a rocking chair overlooking your orchard and not have to turn the steep up to 75db. This product gets 5 stars. Price wise. Operationally. Reliability. Ergonomically. A great little unit. ... show more
