    • great value, quiet, economical on propane
Set name: 4000w Dual Generator
I use this to power my Coleman trailer camper air conditioner. Works well, reasonably quiet though at full speed isn't as quiet as a Honda. For the money, a good buy and replaced my previous genny that was noisy. The indicators for oil work perfectly. It will not run inverter if it is 110 degrees outside, but it will run. Found that making sure it is out of direct sunlight helps. I use on propane, and find it fairly economical to run 20-24 hours on a tank. Also it is more compact (like the Honda) and easier to stow in my camper bulkhead. Starts up reliably on 2nd or third pull (from new hookup) and quick connect hose is a great improvement over threaded hose. ... show more

    • So far great
Set name: 4000w Dual Generator
I thought it was going to be lighter and quieter than my old Champion 31. It’s not. It does have higher watts, which is good. So far I have only been breaking it in but, it starts up easy and seems to work fine. I do like the propane option as well as having an hour meter , which is why I bought this vs buying the Champion version. It also costs less. If anything changes after I start using for real, I will update my review ... show more

    • Great Buy
Set name: 4000w Gas Generator
Arrived as scheduled with everything but gas. I put oil in and added some gas and it started right up. I ran it about 3 or 4 hours so far with a medium load and it handled it just fine. Trying to wait for the 25 hour break-in to put it a bit further to the test. So far everything is good and is relatively quiet compared to another one I had about the same size. Just have to talk a bit louder than normal when you're next to it. Very pleased so far, I hope it will last for a long time. ... show more

Set name: 4000w Gas Generator

Review Image by 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

    • Good dry camping generator, with shore power 30A connection.
Set name: 4000w Dual Generator
I don’t know much about generators but my first time dry camping was with this generator granted I didn’t have to run my air conditioners because of the weather. They seem to have plenty of power. It’s a great size because it’s easy enough to walk around one handed started up every time I pulled the cord and fairly quiet for what it is. I feel like as long as I maintain it well this is gonna be a great investment for dry camping. ... show more

    • Don't let the low price scare you.
Set name: 4000w Gas Generator
This unit is really ok. Don't let the low price scare you. I took a chance and am not sorry. When I first got it, I did all per the instructions. Unfortunately, I had "flooded" the carburetor and removed the spark plug, and dried it off. Then I let the unit sit for 30 minutes. Put the plug back in, and Wham-o, it fired right up! I let it run for over an hour with a small heater plugged in, at 1500 watts. The generator never slowed down and ran until it ran out of gas. Drained the carb. bowel and fogged the cylinder & plug. Now I can let it sit for quite a while with no worries. I also drained the oil after one hour, and man, a lot of small metal chips were noted. I used the magnetic oil plug, and it caught a lot of metal chips as well. I guess this is very common in brand-new engines, so be wise and protect your investment. ... show more
