Verified Purchase

Bought for Hurricane Season

I bought this unit ahead of time to be prepared for Hurricane season. I haven't had to use it yet. I just run it about one a month to keep it up.

Piece of mind

I opted to buy a portable home back up generator opposed to a built in because of the versatility. It will do the job of a built in but I have the option to use it for other things as well as loaning to someone else if I haven’t lost power in the event of a hurricane or other natural disasters. Upon delivery I was impressed with the ease of set up and overall performance of the generator. I expected it to be very loud but was actually surprised that it was not unbearable. Overall very happy with the purchase and not as anxious with the upcoming hurricane season starting.

Great product with excellence performance!

I have the above model Generac portable gas generator, still in the box. I am very familiar with this unit as a good friend of mine has the exact same unit. I assisted him in building a house for his family. We used this unit for about 3 months and it fulfilled all of our needs in this house building project. It was used for long periods of time and only turned off for lunch time and never left us without power. After the power company finally installed a temporary pole and electricity to my friends property, we did stop using the unit. Because of its flawless performance I purchased the same generator and I am looking forward to using it...

Just what I needed

Been through many hurricanes and never needed a generator until hurricane Florence. Bought the generac two days before the storm hit. Lost power the night of the storm. Started the generator on the first pull the next morning and it ran 4 days straight without any issues. Great product. Thanks Generac!

Used 1 winter 44 hours, won’t battery start

Used it for one winter. Started great with battery !Then tried battery start in Spring and it wouldn’t start. Charged battery. no go. Changed battery, no go.Changed spark plug no go! Called customer service and after being on hold for 34 minutes, I told employee my problem and my troubleshooting and she said maybe bad gas, I said it starts manually pull start. She said, maybe new battery is not charged! Checked , full charge. She told me to bring it to local Generac repair shop. Now i gotta rent a truck, lug the 250 pound machine across the state and drop it off to have them check it out. Not sure if its worth the trouble even though its obviously still under warranty til 2023. I heard they were dependable, thats why I bought it. Looks like I’m pull starting for the duration even though the selling point for me was battery start....Bummed out and disappointed!

Won't start.

I bought it at Sam's Club (06 JUN 22) and assembled it per the instructions. I fired it up once and it ran for a few minutes. When I shut it down and attempted to restart it, it wouldn't fire. It just makes backfiring noises. It still doesn't start or run. Needless to say, I am not pleased! Your phone rep was supposed to forward me a list of authorized repair shops, but I have yet to receive it. I want my generator to run in event of a power loss. Please help me to reconcile this situation.

Great machine - runs everything

I bought this generator to replace a much smaller unit so that I could run the electric range, HVAC, refrigerators/freezer, and water pumps in my home. I installed a 50-amp transfer panel and tested the setup with all the circuits pulling power, and the generator never missed a beat. Future plans are to install a 30-amp transfer panel to power the electric water heater, lights, and outlets. Others have remarked that the unit is too heavy to put the wheel kit on without help. I had no such problem - a hydraulic floor jack would probably help a lot.

Great power without breaking the bank

I had researched several brands and models of generators and this 7500W model topped the list each time. Bought it to run tools for home renovation jobs and backup if power was ever lost at home. Does everything I need it to do! Great power for the price! Only downside is noise. This is supposedly noisier than most in its class. This is not an issue for me, but if it was regularly used go home backup, I'd consider a quieter one for running throughout the night.
