Features

  • Powerful Output: 4000 peak watts and 3200 running watts, gas powered by 208CC 4-stroke OHV engine, perfect for RV camping and home backup.
  • Multi-Output Options: Includes 2*120V AC ports, 1*12V DC port, 1*RV port.
  • Long Runtime: Runs for up to 14 hours at 25% load with ECO mode, 2 gallon fuel tank with fuel gauge, allows you to check fuel levels at a glance, keeping you prepared.
  • Low Noise: Under 72 dBA from 23FT away, this generator provides steady power for your home during a power outage or RV nights.
  • Lightweight and Portable: Only 56lbs, easy to move around.
  • Note: All generators are functionally tested in the factory, there may be a slight smell of gas when you receive it. Don't worry about it, it's not second-hand.
  • Important: If you frequently use the inverter generator at an altitude above 4000 feet (about 1200 meters), we recommend installing a high-altitude kit (not include). Without the proper adjustment, the generator may run rough, consume more fuel, or be harder to start. Switch back to the standard jet when returning to low-altitude areas to avoid engine overheating.

    • Great value.
Style: 4400W
Great generator thus far. Easy to start, fairly light weight only about 60 lbs and not loud. It's quieter than most other generators. Only thing is choke is marked backwards. On means as in engine is on and choke is off. Nice appearance and will run my camper. I will update once I have used it more but only tested it so far. Great for the price. ... show more

    • Good Generator
Style: 4400W
Great price on small emergency generator. Was well packed and documented. Easy to read and understand instructions. Fired up on second pull, ran smoothly. Reasonably quiet, can run in ventilated garage during outages.

    • Great value, easy to get running

Very good deal for the money, instructions are easy to follow and no big surprises. Started up on second pull, and works perfectly with a quick test on refrigerator. Also glad it included the oil funnel. I measured the sound using a decibel meter, eco mode is basically 3 decibels quieter, which is noticeable, but not night and day difference. However it is nice to have the option and runs everything I would need on eco mode just fine. ... show more

    • What’s not to love?
Style: 4400W
What’s not to love? It’s affordable. Starts right up with a single pull. A bit louder than I was expecting with the inverter but I can live with it. I can also lift it when it’s full of gas and I can’t lift real heavy stuff like 70Lbs. So I’m guessing it’s somewhere around there.

    • 10w-30 4 stroke Oil not included.
Style: 4400W
I was happy with it. Didn't have to use it for this past winter storm thankfully. I did test it. Ran the fridge and a phone charger just fine. Didn't test how far the tank will go for though. Only one I've ever had so I can't say it was quiet or loud versus the competition. Seemed loud even in eco mode to me, but that's not a big deal. Cons - is it doesn't come with oil. The manual recommends 10w-30 4 stroke oil. Grab you a few bottles on the side. It did come with a decent funnel. Didn't come with a tool to remove red shipping brackets, comes with a super cheap screwdriver/spark plug wrench. The instructions could be better written, a few spelling mistakes. If it's cold the choke goes to the rear, pull the cable, flip the choke to the front. If it's warm you can leave choke on the front and pull the cable. Overall still 5/5. ... show more

    • Reliable, Quiet, and Truly Portable – A Great Emergency Backup

Review Image by Waylon
The media could not be loaded. I purchased the Oxseryn 4400W Inverter Generator specifically for winter storm prep, and it has exceeded expectations. It’s surprisingly quiet and light enough for one person to move without a struggle. During a recent power outage, I ran my refrigerator and several smaller electronics without a hitch. I even did a 'torture test' by plugging in my Weber Searwood 600 pellet grill—it handled the startup and operation perfectly. If you need a dependable backup that won't break your back (or your ears), this is it. ... show more
