Our EPA-certified models meet strict environmental and efficiency standards while delivering consistent power output. Advanced inverter technology protects sensitive electronics and appliances from power fluctuations. EPA Certified • Inverter Technology • Load Management Technology • Overload Protection How to choose a generator with appropriate power? Add up all running watts and additonal starting watts to get your total wattage needed. Note: To prevent overloading, choose one with a rated wattage higher than total wattage needed, or connect two generators in parallel. Can I use this inverter generator at high altitudes? Yes, but please note that engine performance may decrease, we recommend installing a high-altitude kit. A high-altitude carburetor jet (or nozzle) helps adjust the air-fuel mixture for proper combustion, and prevents spark plug fouling. Why is there residual gasoline in the new generator? To ensure quality, all Oxseryn generators are functionally tested in the factory, so there may be a slight smell of gas or minimum residual gasoline when you receive it. 5000W Generator 4400W Generator 2800W Generator 2500W Generator 4800W Generator

    • Nice and quiet.
Set name: G-4400
Not nearly as loud as others. Easy to start. Don't feel heavy when picking it up. I think it's very reliable. Getting 16 hours run time on Eco.

    • Great little inverter generator
Set name: G-5000
Nice and light inverter generator that should be able to handle refrigerator or freezer and sump pump at the same time. Just what I need. I added oil, which I used SAE 10-30 synthetic oil, and it started on the second pull. Ran it for a while, it ran good. Haven't tested it out as far as plugging in appliances or anything else yet, but if and when I do, I will update. But so far, so good. ... show more

Set name: G-4400
Very satisfied with the quality and durability. It has started on the first or second pull every time I've used it. It's been 4 months and I've used it dozens of times. Changed the oil twice with the heavy use and that's been the only maintenance.

    • Super easy start up
Set name: G-4400
This is a great generator so far. Breaking it in as we speak and it's been running like a champ. Started on first pull and didn't even have to pull very hard. Really liking the ECO mode, quiets it down a good bit. Oh and for those that say the choke is backwards its actually not. The sticker is backwards not the choke lol. ... show more

    • Awesome generator
Set name: G-4400
This is a great generator, can't beat it for the price. It fired right up within a few pulls. Doesn't come with oil, but no big deal. I put 10w-30 in it (600ml). Someone said the manual is bad but my manual is great, gives necessary details. It's a little loud (100db next to it and about 75db at 30ft away- not too bad) and it seems very similar to other generators I've had. Upon break-in, it ran 9.6 hours at full power on a tank of fuel (approx 2 gal). Then I changed the oil and put it away for an emergency. Very happy with it and thinking about getting another one for my daughter and her family. Note: The choke label is backwards/opposite, but was easy to figure out. It's been the same on many Chinese engines I've purchased in the past, so I'm used to it. ... show more

    • Easy to use
Set name: G-4400
It took some trouble shooting because the choke can be finicky. But once I found the sweet spot, it worked great. It's louder than I thought it would be but overall it is fine.
