Great Investment

[This review was collected as part of a promotion.] I recently purchased the Generac GP9500E Tri Fuel Portable Generator, and it has proven to be an incredible asset for my power needs. The flexibility to run on gasoline, liquid propane, or natural gas with just a simple turn of a dial is a game-changer, making it incredibly convenient for various situations. With a robust 12,500 starting watts and 9,500 running watts on gas, it delivers consistent power for multiple applications, whether I’m using it for home projects or during emergencies. I appreciate the onboard COsense® technology that provides peace of mind by protecting against hazardous carbon monoxide. The electric start feature is user-friendly, and the included LP connector hose makes transitioning between fuel sources a breeze. Plus, the ergonomic handle and never-flat wheels make it easy to transport. With a solid runtime of up to 9.5 hours at 50% load, this generator truly combines power, reliability, and ease of use, making it an excellent investment for anyone in need of portable power.

This Generac Generator has great features & runs everything I need when there is a power outage.

I bought my Generac RS8000E because a friend of mine said if you want a quality lasting Generator. Then Generac is the one you want. He said the quality goes in before the name goes on. I liked that, & I like the electric starter, large fuel capacity & long run time. At 8,000 watts It has more than enough wattage to run our home. It's easy to move around and it's nice to know it's there when I need it. Our power went off for 4 days this Aug 11th, 2020 from the big storm that went threw the Midwest. That's not going to happen to my family again. Thanks Roger

Great unit with power to spare!

I purchased this generator after a three day power outage in 2011. It just finished its first tour of duty on a seven day outage here in Charleston, WV. It ran my entire house..including central A/C and even provided 120V service to my neighbor. It uses a little over a gallon of gas per hour but it's a small price to pay to keep our lives comfortable in 100 degree heat with no utility power. This is the portable unit to own.

Good choice for Back Up

I did my research and purchased this to replace my Husky 5500. It is a bit louder but was expected. Still quieter than most brands. Built very stable and comes with most important features. I hook it up to a transfer switch and powers most of the house. Starts fast and runs smooth. Looks like it will give me years of satisfaction. Very nice generator.

Excellent

I bought the GP8000E about 6 months ago for my house, I liked Generac so much that I just bought a GP2200i 9/12/2018 and received it today 9/15/2018. I just put oil in it, and going to get some gasoline. This one is for my tools (drills, circular saws etc.) I like Generac products. Thanks, Frank The GP8000E is Excellent The GP2200i I haven't tried yet.

Gets the job done

This unit is able to be stored and rolled out when needed. I use it as home backup generator and it runs everything great. I wish it was quieter, but it’s not too bad. There is some rattling on the heat shield. But once it gets heated up it pretty much goes away.

Great backup for home office.

I purchased as a backup to provide power to deep freezer, refrigerator, and home office computers. It was easy to connect and provides ample power for my needs. I looked at various generator manufacturers for some time. I decided on Generac because it had the features I needed; was available thru my local service station and could be delivered to my home in time to save my refrigerated food from defrosting. I only need it for 26 hours before utility power was restored. I changed the oil so I am ready for next outage. I estimated that saving the stored food paid for half of the cost of the Generator. Not missing the days work paid for the other half.

Good value for the money.

I got a great price on the GP7500 (no electric start) so decided not to suffer through a power outage at the cottage again. It went together easily and my 13 year old started it with the first pull or two. haven't needed it yet, but I'm confident it will do the job well. One drawback is that I had expected it to run quieter.

excellent backup

I own a home in Alaska. Power outages are frequent outside the city, and it's dark a lot in the winter. I needed something to power some lights and a portable heater to keep a room warm during extended outages. Excellent bang for my buck. The on/off switch broke the 2nd time I used this unit, but I just went to the hardware store and picked up a toggle switch and wired it in myself. No biggie.
