    Style: 4000w Inverter Generator

    Review Image by Kevin Hudson Kevin Hudson
    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

    Style: 4000w Inverter Generator
    Ace Up 4000 Watt Worked better than expected. Ran my Fifth wheel on it for hours. Best part was the visual monitor. Has fuel level and Amp Draw. I was able to turn on all the 120V items and it showed a maximum of 24 Amp draw. This is fantastic.

      • Great Little Portable Genny. On/Off Switch Hard To See
    Style: 2300w Inverter Generator
    Loved the performance of this generator! It was easy to set up. It started on one or two pulls. Used to run heat and lights in RV. There is an On/off switch as a black cap that you CANNOT SEE! It would start, run, shut down because the fuel/run switch was not turned on so watch out for this. Not fun in the pouring rain. The unit ran for 8 hours on one tank with a light load. Intend to buy another for a daisy chain to run the whole RV. The unit is light and easy to carry. Much easier than wresting with a100#+ genny. Highly recommend. ... show more

      • 63dB on eco, 71dB running regular without load.
    Style: 2300w Inverter Generator
    Without load this isn't as quiet as the description states. Which is entirely why I wanted to purchase this. Good price for what it is and it IS quieter than a traditional generator. It'll due.
