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

    • Invertor Generator Start Up.
Item Package Quantity: 1
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

    • Dynamite comes in small packages.
Item Package Quantity: 1
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. ... show more

    • Great little generator
Item Package Quantity: 1
Great little generator. Got it to run sound equipment and fans for a tent revival. It cant push a lot of power, but works great for what we needed. We only have a small amp, mic relay, a couple led spotlights and three fans running off it and it keeps it all going! A tank of gas lasts about 10-12 hours. ... 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.

    • Works as promised
Item Package Quantity: 1
4 star as this is still my initial review. It seems to work as expected. It was a little difficult for this elderly lady to start the first time. But it did start. There is nothing to say what oil to get. So I got some 10w40 I will use this for my break in oil and then switch to the recommended 10w30. Initially I am pleased with this generator After using this for a while I am generally happy with it. I still sometimes struggle to start it. But I am a 65 year old woman who can usually get it started. I have not used the 30 amp circuit to run my RV yet as I want to get my rv checked out first. But I do run most of what I need inside my rv straight from the generator. Including my oxygenator which is why I purchased this. When operating my oxygenator it does seem to draw more power as it uses the gas faster. But it does the job. Follow-up if you turn the fuel on and leave it on for a minute or so first… it starts so much faster and easier. I have used it to run the 30 amp circuit on my RV and while it does increase the speed that it uses the fuel it works fine. ... show more
