Heavy, so we purchased a dolly to move it around easier. It would be great if iit had come with wheels on it. Runs extremely quietly

great quietly running machine that does the trick for me who is on oxygen full time and fears power outages that this machine can be the answer for this situation. Impressed and very pleased.

Fairly quiet for the power you get

Bought this unit for camping where we had no power it ran my 13,500 BTU air conditioner no problem. It ran up for a split second then basically went back to idle. Comes with oil just poured it in and gas and gave it a pull.

Great

I bought it for when we have black outs. When I started it on my balcony it’s was loud. I do not want to disturb the neighbors. I thought it Would be quiet. What can I do?

The inverter generator works as advertised. I thought it would start better than it does. It takes at least 4 pulls to get it started. My Briggs lawn mower starts on 1 pull and the generator takes 4 or more. Could be bettered engineered.

What a mess

Opened box to a oil covered generator even though it was shipped with no oil. The oil filler cap was not installed. Spent the next Three hours washing and cleaning up. Can't say how it works yet. I will keep my fingers crossed on that.

Even under full load its very quiet.Does not have a eco switch any more but doesnt seem to be a problem.Respondes very fast to load.Little heavy but manageable. Great quality and unlike alot of others parts are readily available.

Perfect

Arrived as planned! Packaged was perfect! Added oil and gas first pull started right up? Load tested it after 1hour of running! I’m highly pleased! For the money you can’t beat this unit! Highly recommend. I bought the GP3300i

Didn't work for me

It says this generator will run a 15000 btu RV air conditioner. But it kicks to overload every time. I have a small 28 ft pull camper. Buy a bigger one or a different brand. Now I have a generator I'll never use. For 800.00

Started on first pull

Literally. Put gas in. Pulled 1x. Started right up. Used to put up a bat house on a brick wall using hammer drill. Quiet enough. Steady power. Easy to lug around. I’m satisfied and looking for other projects.
