Needs to be in a ventilated area

[This review was collected as part of a promotion.] So far energy efficient for 8 hours of work used it for power tool battery charge, lights and AC unit. Noise level is ok easy to move around and handle.

Push button start

My wife and I bought our Generac about 4 months ago due to all the power outages happening . I am so glad we did it has been the best investment for us to help power the house when the electricity goes off

Weston Trawick's guys are awesome!

Bought my Generac from Weston Trawick and they set me up and tested it. 2 days later power went out for 6 hours. Cranked right up! Thank you, Weston Trawick,!

Great generator .

I didn’t use yet , but I test it monthly, the CO2 sensor works perfect. Nice gas capacity and the power supplied looks really stable. Extremely easy to move.

Great Product!

I bought this on our way back from Myrtle Beach because we had no power in Greenville,SC because of Helene. Definitely did the job and so glad we bought it before we got back home. There was none to be found locally.

Great generator!

[This review was collected as part of a promotion.] I highly recommend this product it was very durable, and it was very easy to set up and use. The noise level is similar to any portable generator. It has come in very handy when the power is out.

Awesome, easy to use generator!

[This review was collected as part of a promotion.] This generator is awesome. I was able to set it up alone- so simple! I love that it has three fuel options as well. I think my favorite part is the battery start- it fires up so quickly!

Piece of mind

I bought the generator a couple of months ago to prepare for any power outage and haven’t had to use it yet. It’s great knowing we are prepared for an issue that WILL occur.

Will run the whole house.

Bought generator on Amazon black Tuesday. Still breaking it in. Electrician said it was a good product. Starts easy with on or two pulls . Hope I never have to use it to run the house but if bad weather sets in I will be ok.
