Seems well made. very good deal.
The generator is a reasonable size, generally manageable for one man to lift or load. Started up on the second pull. Choke worked very well. The engine is a good size and it takes a healthy pull to start. Hopefully the pull starter will hold up well. In Eco mode, it idles down lower and is pretty quiet. My purpose is emergency use, so I haven't given it a complete test yet. All seems good so far though. Included was a plug end to plug into the RV output receptacle. This will be useful in making a cord to feed my breaker box.

Look no further
I've owned several generators over the years, but the PowerSmart 4800-watt stands out as the best by far. I picked it up shortly after moving to Florida, knowing I’d need a reliable backup for household essentials during power outages. Right out of the box, it was ready to go — no assembly required. After adding oil and gas, it started with just a few pulls of the cord and ran much quieter than any generator I’ve had before. I placed it about 10 feet from the house, and with the door closed, I couldn’t hear it inside at all. Just three weeks after the purchase, a nasty tropical storm knocked out our power. Thankfully, I had also bought two 75-foot, 12-gauge extension cords and two 50-foot, 10-gauge cords — each with three outlets, giving me 12 outlets total. I ran the cords through the house and plugged in three standing fans, three lamps, a full-size Samsung refrigerator, a Primo water cooler, a TV, a modem, a portable air conditioner, and my laptop. With everything running, the generator used a third of its available wattage. We also interchanged a stand-alone 2-burner electric range for boiling water, a Gourmia toaster oven/air fryer, and a coffee maker when needed. The generator ran continuously for over 24 hours, powering all 12 sockets without any issues. The PowerSmart 4800 is solidly built, easy to operate, and it delivered reliable electricity when we needed it most. If you're looking for a dependable generator to keep your essentials running during a blackout, this is it.

A great generator for camping
My power smart 4800 W startup inverter generator has been very dependable, the only thing I wish I would have gotten would have been a remote start but other than that it powers my entire 26 ft motorhome with no issue, we use it for boondocking.

Good generator, bad battery!
Runs great, very quiet other than the wheels rattling. Battery for the auto start died after the first use.

Smooth, quiet, and efficiency
I am general contractor, we need the power generator for a project that has no electricity. The crew said can't go wrong with a Honda Brand, however the price is $2000ish for the similar features and load. There are many generators available from AMZN, I narrowed to 7 different brands, my final 2 were this and the Champion Brand, I picked this over the Champion due to it is slightly more efficiency and the look. This unit runs very smooth, and pretty quiet. Especially with its ECO mode, one tank of gas can last for few days. The down side for me is that the unit is about 70lbs, which is fine, however with oil and fuel it has over 100lbs. So for me to upload and unload from my work truck is a bite challenge. Otherwise, this is a outstanding generator. I am happy with the purchase.

Total junk
Generator doesn’t work, also gasoline tank has a piece of fabric inside. And doesn’t have the start button. A total joke.

Don’t buy!
There is something wrong with the unit. First time using it pull cord broke. I was told part was being sent then it couldn’t be sent to my address. Now being told again it has been shipped to me. Will see if it shows up. Because I was over my time to send it back I could only get a 50% rebate off this unit even though it was the first time it was used. I had a friend buy the same unit and the same thing happened with his. Definitely something wrong and needs to be fixed. Do not recommend buying this or use it as soon as you purchase so if the same thing happens you can get your money back.

Dented Bar
I just received my generator. It’s brand new out of the box but the Metal bar is already defective/ dented . It’s pretty disappointing when you’re paying almost $900 for brand new generator. Pictures are attached below
