Description

Remember when you had clean and quiet portable power? The WEN 4800-Watt Inverter Generator provides clean energy, free of voltage spikes and drops, without all the noise of a regular generator. Produce up to 4800 surge watts and 4000 rated watts of power. Our 224cc engine operates at a modest 62 decibels at quarter load. This limits its invasiveness while camping, hunting, tailgating, and restoring backup power. The WEN 4800W Inverter Generator is also equipped with fuel shutoff. This feature turns off the flow of fuel, allowing for 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 to run laptops, cellphones, monitors, tablets and other sensitive electronics. The built-in wheels and telescoping handle make for easy portability while the ultra-efficient 1.9-gallon tank provides up to 7 hours of half-load run time. The fully-packed panel comes equipped with four three-prong 120V NEMA 5-20R receptacles, one 12V DC receptacle, one 120V TT-30R RV receptacle, and two 5V USB ports. 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 any two WEN inverter 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 this is a WEN Product, your inverter generator comes backed by a 3-year limited 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.

    • Reliable Power Source and Easy to Use
Style: Recoil Start
This generator has been a great purchase for my home. It provides reliable backup power during outages and runs smoothly without issues. The setup was simple, and the instructions were clear. I was impressed by how quickly it starts up and how much power it delivers — it easily handles my fridge, lights, and a few other essentials. It’s also not as loud as I expected, which is a big plus. The fuel efficiency is good, and the build feels durable and long-lasting. ... show more

    • Very impressive unit very sturdy and quiet very well built
Style: Recoil Start
I purchased this a year ago because some of the medication‘s that I take are stored in the refrigerator and are quite expensive. I got this as a backup so if the power goes out it can power the refrigerator. A medium sized freezer in the garage has done very well so far without any problems or issues just make sure to follow the instructions and do as they say, keep a check on the oil to make sure it’s at the proper level and make sure to start it once a month and do a generator test as recommended in the manual. It has started every time every month that a test has been done on it very very happy with my purchase very well built. The unit is quiet sturdy and runs very smoothly. highly recommend this unit and seems to be reasonably fuel efficient. ... show more

    • Amazing!
Style: Recoil Start
We just lost power for 9 days during the Palisades fire and this generator shipped the day after I ordered and came in literally 20-ish minutes before our power went out. I had a neighbor help set it up and looked very easy to do. I was able to easily start it by myself and run multiple extension cords to power essentials. We plugged wifi, tv, phone chargers, refrigerator, deep freezer, cappuccino machine, and air fryer. When using the kitchen appliances we would unplug the deep freezer or refrigerator to make sure we didn’t exceed wattage. Very easy to just unplug and plug what was needed in. This saved us! The only thing I wish we could have done was plugged our water heater in and some better lighting. We are now looking at the higher wattage as we are already looking at another power shutoff Monday. I have recommended this one to so many people already! 9 straight days of use from the moment we took it out of the box. I recommend getting 50+ feet for the cords and power strips to plug in multiple things via extension cords. It ran all night long without going off from gas usage. We got 3 2gallon gas cans and a 5 gallon and used a siphoning device for that to transfer gas. It would last 8 hours easy on a tank. Easy peasy! I started it multiple times no husband needed. A child could operate easily. Very user friendly. Highly recommend. Great price and it’s very lovely looking and quiet. The guys that helped set me up asked me for the link bc they couldn’t believe how well it worked and how quiet it was. Thanks for saving our lives this last week +! Sorry for the jumbled review but wanted to make sure to get all the information out there. ... show more

This little generator is the best value I have ever seen. The quality is exceptionally good, and it always starts on the first or second pull. The output of the inverter Meets or Exceeds the Rated Capacity for continuous as well as surge load. (I'm an electrical engineer, and generators are something of a hobby to me. I own a lot of them) This is Huge because a lot of other inverter generators do not come close to the rated output, or suffer Serious voltage drops when subjected to load spikes (like starting an air conditioner). These WEN units provide exceptional surge capability and excel at starting inductive loads like air conditioners (provided you have a soft-start installed). I have a pair of these 56477i units with manual start. They are so easy to start, I see the electric start option as overkill and something else that needs a battery to maintain. Two of these units (with my self-designed Phase Sync Box that creates 240v Split-Phase Power) run my Entire House, including the 4-Ton AC, a 1-Ton Mini-Split AC, Two Refrigerators, A Chest Freezer, and all lights and computers Simultaneously ! I just alternate which one of these I take on trips with my RV so they get even usage, and while at home the pair of them make a very portable 9600 Watt Whole-House Generator (for 1/3rd the cost). I also have four of the 2350 watt suitcase-style generators from WEN. (The 56235i models) I can also say that a pair of the 2350 units do exactly match the power and performance of the 4800. I also run my entire house exactly as stated above using FOUR of the 2350 units with my Phase-Sync Box. Here are a couple of pictures. All I can say is that these units provide exceptional bang for the buck. Keep the oil changed often as these little engines do not have oil filters, and keep fuel stabilizer in the gas. ... show more
