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

Quite clean power

The generator is easy to start and operate. It's also pretty quiet from what I'm used to. It uses very little fuel. It is very good quality. Generac is a brand i trust.

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.

Great for camping!

[This review was collected as part of a promotion.] This was perfect for camping! It powered everything we needed and was surprisingly very quiet compared to other generators I have seen used. Highly recommend!

Good features and quiet running.

Love the new generator, with an easy start electric starter. I went thru the process of adding the oil, etc. The generator arrived with a dead battery. I charged the battery , it started and ran quietly and efficently. l started the generator once a week just to keep ths system operational. My only problem is I need to charge the battery every time I go to start the generator. The battery does not hold a charge. The battery arrived needing a charge, and every time I go to start the generator I still need to charge the battery again.

Nice and Quite

Purchased 2 of these portable generators for our RV they are very quite and run great. We like the features on the gas gage and how many hours left till empty are awesome no longer waiting till they run out to see to put in more gas. Takes out the guessing game, also like the feature on how much power your consuming as well.

Very pleased

Purchased through Amazon, arrived in a timely manner in perfect condition. Unpacked, added oil and ethanol-free gas, it started on the 2nd pull. Very satisfied with how quiet it is, will be using it with a small travel trailer. Let it run for 20 minutes with a light load, then shut down. A few hours later it started first pull and I connected to the trailer and started the A/C. The generator was only about 2 feet from the trailer and I couldn't hear it inside with the A/C running. Let it run for 30 minutes, then shut it down. So far, so good. Had to buy the adapter plug, no big deal.
