Great Generator with tons of power

Bought this generator to power four refrigerator/freezers in the event of power loss. It performed like a champ for two days straight. More than enough power for the four plus lots in reserve. It is a heavy generator (200+ lbs) to move, but I can live with that considering the fantastic oversized wheels and well designed handles to move it around. After putting together and filling with oil and gas (approximately 30 minutes), it took only two pulls of the rope to start. Electric start was not used because battery was low. Charger for battery did not seem to charge enough to use electric start. I would recommend having a portable jump starter if you plan to use the electric start. Quieter than I expected when running. Hobbs meter to view total operating time is a great plus to know when to service. Well designed circuit breaker for the multiple outlets. Bottom line -- this is a great value generator that I would recommend.

Power to spare

I bought this during the power outage of August. Setup was easy, the generator worked flawlessly. It powered half of my house with extension cords. 2 refrigerators, a chest freezer, sump pump, ceiling fans and lights. Had my cable modem and wifi running as well as 2 8,000 BTU air conditioners. The only issue I ran into was that the cushions for the handlebars were missing. All it took was a few emails and Generac took care of that for me.

Pleased with our purchase

We lost power due to severe storms that roared through our area. The sump pump was flooding out into the basement and we had just filled our freezer so we needed electricity. Because of the widespread damage from the storms it was evident we were not getting our power on anytime soon. Purchased a Generac 8000 watt unit and we were able to get through the blackout! The generator supplied more than enough power and ran several hours on a tank of gas - very pleased with our purchase!

Easy set up

I purchased this a month ago at Farm and Fleet. Set up was super easy. It fired right up, the battery already had a full charge on it for the starter. There are directions on the machine so when the power does go out and your in a rush you don’t have to go looking for anything it’s all on the machine and ready to get your house back up and running.

Easy to use

I bought the 8063 tri fuel generator at a local hardware store, I local electrician installed a transfer switch. Approximately a week later we had a power outage. The generator worked as expected it did seem to be a little hard to start i was using propane, but that may be normal I don't have experience with using propane for fuel.

Dependable power source

We had an extended power outage. This was my first portable generator. It assembled easily and worked well supplying power to my home. It was the only unit available due to the area wide power outage. My only complaint is the noise level while running.

Great features compared to other generators

I'm 70 years old and live alone. When I purchased this product generators were in very high demand due to frequent power outages and severe storms. It was the only one I could find. There's no doubt that it's a wonderful product, but it's too heavy for me, and I don't have the upper body strength to start it with the pull cord. I need to find a neighbor to help, usually during driving rain and terrible weather conditions-not ideal times to ask for help when neighbors were experiencing similar struggles.

Good generators but...

Bought 2 of these. In FL, I start them about every 6 months. At 9 months old, one did not start. H Depot didn't even have them on file as a purchase. Generac fixed that. I got the repair but had to rent a uhaul - 2 separate trips to take to the shop and back home. I think it should have been fixed on site, considering I spent almost 2k with them. I do like them though

Terrible Experience!

At first I loved my purchase but within operating the generator for 10 hours, one set of outlets has shorted out. There was no water damage, simply stopped working. When I contacted support I was told that I needed to deal with wherever I bought it (authorized dealer) or a repair location. Funny though- repair locations they gave me refuse warranty work, and authorized dealer tells me it’s a final sale, best of luck. Terrible experience to spend $1k on a generator and have it working 50% within a day!
