    • Once you figure out the choke then start up should be hassle free
Style: 4000W
I must say I absolutely love this, it gets the job done, and it I'd just as the description says long run time with low noise, super easy to use, my country was devastated by hurricane Melissa so this generator has become a lifeline for our family. You should definitely buy it you won't be disappointed. ... show more

    • Invertor Generator Start Up.
Style: 4000W
So far I am impressed. 56 pounds so not difficult to lift and move. Oil level not specified so I had to pour and check multiple times. I think in the end it took about 12 ozs. Put gas in, turned choke to on, opened fuel line., put On switch on. 1 pull to prime. 2nd pull “vroooom” started up. Quiet, in economy mode even quieter. Plugged in light bulb to be sure electricity was coming out. Shut it off and re-started in one pull. I especially like the removable gas filter in the tank, the shut off gas line and the drain screw on the carburetor. These features are especially helpful when storing unit and preventing gas from gumming up. Hopefully this will not disappoint me when I put it to task in an emergency. Right now 4 + stars at this price and ease of start up. ... show more

    • Absolutely worth the price. Runs great.

Review Image by April Collins April Collins
So far so good. It was easy to star two pulls We took it camping to hook up to our camper.. Ran it for about 5 hours and only used a quarter tank of gas. Moved it about 30 feet behind the camper and we barely heard it in side. Was able to have a conversation outside without having to scream. It’s a little heavy for me but my husband had no problems moving it. ... show more

    • Dynamite comes in small packages.
Style: 4000W
Absolutely floored for the runtime on this little dude. For initial break in ran a half tank of gas through it in eco mode, got right at 7 hours of runtime on 1 gallon of zero ethanol 91 octane. Was pushing everything in my small camper but the AC for all but the last hour and then turned the AC on. 13500 BTU unit (from 1989) kicked it out of eco finally but it handled the spike like a champ, no faults or overloads. Quieter than I expected, was easy to start, 4 cranks from dry and it fired right up. Unit is compact and easy to store and move as well. Time will tell how long it holds up, but initial impressions are this little generator punches well above its weight class. Addendum: really out it though its paces finally. Had a power outage and had to rely on this to keep everything running through the night. Filled the tank and fired it up at 10 pm. Eco mode on after the initial surge connecting it. At 6 am it was still running. It was just about empty, but 10 hours of runtime on 2 gallons of fuel with a light load is far beyond my expectations for the price. ... show more

I bought this generator to use with my RV because it is light weight but can still run the AC. However it is not quiet and the choke labeling is backwards from what I am used to. All in all happy with the unit.

    • DON'T PURCHASE THIS GENERATOR UNLESS YOU WANT NOTHING BUT PROBLEMS!!!!
Style: 4000W
DON'T PURCHASE THIS GENERATOR UNLESS YOU WANT NOTHING BUT PROBLEMS!!!! The original generator I purchased ended up cutting off when I used the a/c so I was sent another one that was supposed to be brand new but now I'm not so sure it wasn't refurbished! The other one powers up while it's running as if the voltage dropped (I made the mistake of getting a $50 refund cause I was told, by the seller that it wasn't a big problem, and I doubt anything else will be done to make it right) now it's not turning off when I use the on/off switch and I actually have to use the choke to turn it off! Not sure what's going to happen with it next! I thought and was told that the Sportsman generator is a piece of garbage but I believe this generator is actually worse than that!!! DON'T PURCHASE THIS GENERATOR!!!! ... show more

    • Great portable INVERTER generator.
Style: 4000W
Unlike my other 4000 watt generators, this one is light enough to carry at under 60 lbs. Starts easily and isn't very loud. I used it to power my mig welder when a neighbor needed a gate fixed. At only about 10 lbs heavier than a 2000 watt generator, this one punches way outside of it's weight class. Unlike other inverter generators, this one has an open frame that makes maintenance much easier. ... show more
