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.

    • 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

    • Get the Protection Plan, but awesome generator!
Size: 3800W + Electric Start
We live on a boat and bought this generator about a year ago. We use it almost every day to supplement our solar and wind generators. It is the easiest generator we’ve ever had to start. You basically turn a knob and it fires right up. The fuel tank is huge. Feed it at 10 p.m. and it runs until almost 9 a.m. at low. Plus, when shutting it down, you can just turn the “knob” to off and it works until it runs out of fuel, so you aren’t fouling the carburetor with old fuel if it sits for a while. Really great feature if it’s only used occasionally. Ours recently had an issue with the spark plug housing causing a voltage fault and inoperability. Like I said, we use ours pretty much daily. My husband did research and says this seems to be somewhat common and parts are available but hard to find. Thus my recommendation for the protection plan. We contacted Wen and found that the warrantee was for 3 years OR 500 hours. So, ours was now beyond the Wen warrantee. Yay, Asurion Protection Plan! We contacted Asurion and they declared it was a loss. So, we re-bought the exact same generator and are anxiously awaiting its arrival. So, yes, this is a great generator. Depending on your use, you might have issues. Love it enough that we bought it again. Just as an aside, since we live in a harbor with noise regulation, the decibel ratings were very important to us. There have been countless times one of us has pulled up to our boat in our dinghy and had to check to see if the generator was running. It’s that quiet. Believe it or not, the Honda 2200 we’ve rented while waiting on the new generator to arrive is MUCH louder. We can hear the rental generator while in bed with fans and air conditioning running (it’s the Florida Keys, y’all. Blistering hot even in October). The Wen, we have to get up and go check to see if it’s still running. Pretty impressive for a much more robust machine. Yes, it’s heavy but it’s a great generator. Absolutely get one! Just make sure to get the protection plan, especially if you plan to use it a lot. ... show more

    • Excellent generator
Size: 3800W + Electric Start
I have owned this generator now for almost 5 years. It will be 5 in December, 2026. I have used and abused this generator more than the average person. I boondock camp almost every other weekend and this generator is used to run AC and appliances all the time. I have 770 hours on the meter as of writing this review. I currently own a Brinkley Z2900 and can run both AC units, charge phones, fans, TVs and whatever else all night on 1 tank of fuel. I did a break in period when I intitally purchased it, but then change the oil after each season (summer/winter). I don't do it when it says to. If i did it every 25 hours, I would be doing it almost every weekend in the summer. The generator is quite and strong. It reacts quickly to power surges and I have never had any issues with sensitive appliances. I used it at one point for 8 days straight during a massive hurricane power outage at my house. After about day 4, it died for the first time ever since purchase. I put a new spark plug in it, changed the oil, and fired it right back up. Ran it for another 3 straight days afterwards. When we have the windows up in the camper, I cannot hear this generator running at all. Even when it kicks into high RPM mode, it is very Quite. My next purchase if this generator ever fails, will be 2 smaller Wens that I can carry around and parallel together. Would love to give the 2800 watt version a shot but can't justify it because this one is just so awesome. Really my only compaint is the weight, which I knew before purchase and have dealt with just fine. I toss it in the "garage" of the 5th wheel while traveling and it fits great. The size is perfect in that aspect. Honestly, I cannot say enough good things about this generator. It has been rock solid. I almost bought a super expensive Honda because of the "last forever" reputation but I am so glad I didn't. I imagine that I will give this to my neighbor or something when I finally decide to buy the 2 smaller ones that I want. ... show more

    • Reliable beast during the Texas winter storm. Highly recommend!
Size: 3800W + Electric Start
Ok, so to preface this, I bought this generator last for Hurricane Season here in Houston, TX. Up until now I had not had a need for it but this week during the unusual winter storm in Texas that left us all without power, we were the lucky ones because of this generator. A few notes I'd like to share: 1. I had my fridge, gas furnace and blower, a couple TVs, internet, lights, etc. hooked up and even with the heat blowing the capacity never broke the 20% mark. Plenty of power for all of your needs during a winter event. I do not believe there is enough power in the 3800 Watt unit to power an AC system, but that was of no concern during this event. 2. It ran without issue for 30 hours straight and used just over 2 gallons of gas. With the low demand of my uses I kept it in eco mode the whole time. 3. It was barely audible on my back patio. Very quiet unit. 4. I left it outside before actually needing it for two days in 10-20 degree weather and it started right up. Needed to pull it because the battery was weak from the cold, but having both options is great. A couple thing to note: When it first arrived it would not start at all. The service and parts people were outstanding AND they were Americans who knew their stuff. He had my solution and emailed me repair procedures at my request because I have basic tool skills and was willing to make a quick fix. The spark plug cap broke during shipping, which is apparently more common than it should be, but they sent a replacement out right away and it arrived in just a few days. To be on the safe side I was able to buy one for $4 at a shop and put it on myself, which was easy. SO, if yours doesn't start out of the box, take off the side and check that. Easy fix. My conclusion: started, worked perfectly for a couple days, sips gas, is quiet, and customer service is outstanding. What's not to love? I'm going to be adding their bigger model as well to run my A/C during Houston heat outages, but I'll be sticking with WEN. One other note: I highly recommend, if you're using this for your home, buying a generator transfer switch for your house so you can just plug it in directly to the box and run pre-selected parts of your home. Have a licensed professional do the work. ... show more

    • 3 year Review. It's a great unit
Size: 3800W + Electric Start
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

    • Nice generator
Size: 3800W + Electric Start
Would have gave this item 5 stars but it arrived late in a damaged box. However the item was not damaged. This thing works great. I've seen some reviews saying it is not quite. Dont know if something is wrong with the one they have, but it is very quiet. I had a predator 3500 before this one. The wen is just as quiet as the predator and has more running watts. I use it on my fifth wheel camper. It is not bad lifting onto my cargo carrier and is very maneuverable on the ground. Starts very nicely. You just have to remember if your using the auto off feature that its gonna crank a little longer on the next start due to the carburetor being empty. I did alot of research on generators before purchasing this item the 3800 watt. Hope this helps with someone else's decision. ... show more

For those looking for the quick bottom line review: I am extremely happy with this generator. It has more than enough power to keep my family of 6, with 4 tech dependent children, relatively calm and comfortable for days without power. It is also reasonable sound level wise to run through the night, living in a housing community with neighbors very close. No, I would not attempt to power an air conditioner. Power output: 5/5 Noise: 5/5 Portability: 4/5 Easy of use: 5/5 Easy of care/maintenance: 5/5 Overall look: 5/5 The only 2 cons I can come up with: - It's heavy - I can lift it myself to get it into my SUV, but I could not carry it far. It does however have wheels and a pull out handle to make rolling it around quite easy. - after using for about a day an a half, it began leaking a VERY small amount of oil from around the oil drainage tube. No noticeable amount when checking the dipstick --------------------------------------------------------- For those looking for an in-depth review with details (like I was) to help make a purchase decision... here ya go.. Background: I am a mid thirties computer programmer, living with my girlfriend and our 4 kids (ages 8-17). We live in a townhouse that's part of a very stereotypical upper middle class housing community. Our 4 kids are very technology and internet dependent, spreading across streaming services, gaming, and social media. Additionally, I work from home and am dependent on my full setup (monitors, laptop, switches, etc..) for my job. I purchased this generator after losing power for 5 days as a result of a bad thunderstorm with lots of downed trees (and wires) in the area. At the time, I didn't have one at all, but borrowed an uncle's 3400 watt portable generator for the last few days. It was a typical, cheap, "camping" style generator with an open caged design. It was incredibly loud, resulting in countless mean looks and nasty comments from neighbors. It also produced "dirty" power, so we were only able to use it for the freezers and fridge, not any of the electronics. It was also notably lacking in information output, like power consumption, fuel level, etc.. After that experience, I did a bunch of research and landed on this Wen Inverter Generator. I purchased in mid May 2020, and got my first full usage in July 2020 when another storm knocked out power for 3 days. Used the generator basically non-stop for 3 days without issue. Power: Most importantly, this produces "clean" power that is safe to use for whatever, electronics or other. While using this generator, I never used even 50% of its available output. Much of the time using less than 25%, depending on freezer/fridge compressors being on/off. With that, I was able to power the following (at least): 2 deep chest freezers, a standard refrigerator/freezer combo, sump pump, dehumidifier, cable modem, 3 routers, several laptops, a 24" monitor, 8 large stand/box fans, 6 lamps, as many as 10 phones/tablets, plus a toaster and coffee pot as needed. I also successfully ran a 65" TV without issue, but did not keep that on, just because. Overall, plenty of power. Noise: This is the big one everyone is worried about. Being honest, I was rather shocked and pleased at how quietly this runs. To be clear, this is not silent! It's a generator. If you're expecting no noise, or similar to a small fan, you're kidding yourself. However, my general assessment from walking around my neighborhood in the evenings (something I do regularly, power or no) is that it produces slightly less noise than a typical outdoor central air unit. Standing directly next to it, you can hold a conversation without yelling. At 15+ ft away, it's background noise and overall "not irritating". Standing about 10ft away from it, I could hear my neighbor's generator (about 100 ft away) overtop of my own. At one point when coming back from a walk, I was convinced it had shut off for some reason because I couldn't hear it until I was quite close. I had no reservations about noise level when running this all night. Fuel Consumption: The tank is admittedly smaller than I was thinking I'd like when I bought it. However, it has turned out to not be an issue. I was refueling about every 12 hours, without ever running out. I expect (with the load noted above) it would last about 14-15 hrs on a full tank. And a 5 gallon gas can is perfect for two fillings (plus a little extra). Look/Feel: This generator looks gorgeous (as far a generators are concerned). It's has a modern, clean look, especially compared to it's competitors. It feels very solid, sturdy, and well built. It also feels very intelligently designed, with easy of use/care in mind. It has a fuel level and power consumption gauge, presented as LED bars at 25% intervals. Doesn't give exact values in the display, but enough to be helpful, and more than many others. Starting: Since this generator contains a battery, after the first start (once the battery has power), it will start electronically by simply turning the dial. On the first start, the pull cord starts it with ease, requiring very little pulling effort/energy. It is NOT like starting a lawn mower or weed wacker that takes a very quick, strong pull. Care/Maintenance: This is where I was quite pleasantly surprised. This generator is clearly built with ease of maintenance in mind. Which stands out compared to other generators I have interacted with. Most notably, when you are done using your generator and ready to store it longer term, you need to drain the gasoline from it to keep it in good working order. I have taken screenshots of me doing this process to showcase just how easy it is. Remove 2 screws to take the side panel off. Pull the pre-attached tube out to the side and direct towards gasoline container. Loosen a single screw and let drain. Then turn the starting dial to "run" and let drain again. That's it... The oil dipstick and access is not fantastic, but equal to any others I've seen. I also note that there is an easy drainage tube for the oil as well, when changing the oil is necessary. There is also easy access to change a sparkplug. Also worth noting that I purchased a 10 gauge RV cord (pictured) that converts to a 3-way standard 3 prong plug. I also purchased several long 12 gauge three way extension cords to plug into that RV cord. That is how I connected everything. No cords were even warm to the touch. Overall, I would strongly recommend this generator to anyone, including my own family (which I have already done). I would definitely buy another one myself, if I needed it for some reason. Hope this proves informative to someone else. ... show more

    • This is a great generator for the money, and quiet!
Size: 3800W + Electric Start
I did a lot of research before deciding on this generator. There are others that are cheaper, and definitely lighter that this one. But in my opinion there is a reason why this one stands above the others out there. For one the run time on a single fill up. It can run for up to 12 hours on a single tank if gas when in eco mode. The others had run times ranging anywhere from 4 hours on a tank to 8-9 hours. I don't want to be filling a gas tank in 3:00 in the morning while I'm running my AC in my camper. I was very surprised and how quiet this generator is. Even when running my AC I could stand right by it and carry on a conversation. It is heavy compared to some of the others, but to me that just means it's built well. The electric start is also a great plus. The built in handle makes it easy to move despite its weight. It is also easy to fill and change the oil. Some of the other units are very hard to service, not this one! I ran my AC, fridge, microwave and coffee pot in my camper and this baby barely kicked up at all. Do your research, and compare. This is a great generator for the money, and very well built. ... show more
