    • Same weight and not much larger than much lower capacity inverter generators
Style: 4000w Inverter Generator
So far so good. Three pools and it started right up on recreation 90 no ethanol fuel. Plugged it into the boat and it’s running the air conditioning unit without any problem.. not whisper, quiet. It’s easy to handle to move around and the fact that it has the 30 amp receptacle and higher output at steady 3500 continuous makes it much more versatile than my 2200 harbor freight predator. The predator has been an outstanding unit, but this one was less expensive. Currently the predator cost about $600 and this one was about $500. ... show more

I purchased this generator simply for the low price, huge mistake. I added oil and gas and tried cranking but not happening. I pulled the spark plug and it was wet from the gas so I tested the spark. No spark. I pulled a few more times and the spark mysteriously returned and the generator started. Still haven't figured that one out. When the generator started it ran for three seconds at wide open throttle and died. Tried several more times with the same results. I then noticed that the stepper motor on top of the carburetor had fallen apart. I brought the generator in the house and set it on the kitchen table so I could fish the broken parts from the generator. To my surprise gas began pouring from the generator. Now my wife is pissed. I contacted Amazon to try to get a resolution only to be told it was a nonreturnable item and I would have to contact the manufacturer. Good luck with that! They don't answer the phone number provided and the only response i got through email so far is suggestions on what the issues might be. 🤔 Amazon needs to step in and make this right. Refund my money or send me a working nondefected generator. Update: Amazon did provide a refund! Thanks ... show more

When I got the generator out of the box and got it ready to to it would not run on eco or anything with the chock off then it would not run at all . I took the side cover off and it had a loss wire no the control panel. Put it on and it runs fine.
