Quality product

Our power has been out for the last 3 days from hurricane dorian, this generator has worked great. We switched our house over to the Generac 8000W generator as soon as we lost power. Fired up AC, some lights, a few receptacles and refrigerator, WORKS GREAT and has worked for us on a tank of gas for 17hrs. HOT HUMID days with no power, glad we have our Generac generator.

Delivers as you would expect it to

Bought this generator during a storm where half our province was out of power for over a week. I utilize it as a whole home backup generator, it has enough power to run my well pump and sump pump as well as heating my water when I need it to. it starts right up without hesitation and runs smoothly. The frame and wheels are very rugged to carry it around since it is on the heavy side. the only down fall that I found with it was that it is quite noisy so I will be building an insulated cover for it. Extremely satisfied, never looked back.

Hurricane Auxiliary Power

I bought a GP8000e 3 years ago but didn’t need to use it until now. I turned this generator on Wednesday night after hurricane Ian had passed. It’s been running for 5 days straight. I do change the oil every day, not sure if that’s necessary. It’s been running the lights, two air conditioners, tv, refrigerator… I’ve even used the washing machine.

Excellent quality, design and reliability

I don't write many reviews but we are in an ice storm power outage. I dusted off my Generac 6500 XL which I purchased in 1999. It started right up and is running my entire house - well pump, furnace, frig, and lights including Christmas lights. . It is 17 degrees out. This generator is great. It starts first or second pull every time. It will be hard to find a replacement to match this one if it every wears out. Happy generating.

Fantastic

[This review was collected as part of a promotion.] Oh wow! What an amazing opportunity to try this. We did use natural gas in this just to try it out and it was incredibly powerful! The unit is noisy but not so much that it would be a disturbance. Our old generator was much louder. This unit is quite compact and easy to move around. It will definitely come in handy when the power goes out! Love that it takes 3 different types of fuel too. Very convenient. Generac is such a trusted brand that lasts too!

Works every time

This Generator starts every time and I have had no problems in 2 years. Shortly after I got this unit I had shoulder surgery. The design of the unit allowed me to set a couple short pieces of 2x4 on top to straddle the fuel line and set the 5 Gallon gas can right on top over the fill hole using only one arm. The only problem I had with this unit was when I let the oil level get too low and the unit would not start without enough oil....good safety catch! I put oil in it and off it went without a hitch. I ran a refrigerator, small freezer, sump pump, well pump, furnace, TV, garage door opener, and some lights with no problems. I have used it several times now when we loose power here in the country and it has never failed me.

Love the Simplicity

I wanted to get something to have as a backup to power our homes freezer and refrigerator along with a few small appliances. My main focus was simplicity. I need to make sure my wife could operate the unit while I was overseas and not needing to read an owners manual to operate it. Purchasing this product was a great decision and I am very satisfied with the whole package. It really is a peace of mind.

For the price, should have flat-free tires and covers on outlets.

I'm pleased with the overall look and the attention to engineering details. The generator appears to have been designed for ease of maintenance. I like the location of the oil dipstick, oil filter and the oil fill on the engine. I also liked the oil drain hose which will make it easier to not make a mess when draining the motor oil. I would have liked for it to have flat-free tires. This generator will be stored for long periods of time between use. I do not look forward to having to air up tires when I need to move it to where it will be needed during a power outage. I would have also liked covers over the electrical outlets to keep mud daubers from plugging the outlets with mud during storage. I have not used the generator yet, but overall I like what I see based on decades of experience as a railroad signal maintainer running generators at signal locations during power outages.

Amazing quality and great value

[This review was collected as part of a promotion.] due in no small part to recent events on the eastern seaboard, we felt it necessary to purchase a portable generator given to volatile weather here. we decided to go with the best name in the business: Generac. we were certainly not disappointed. the 8000 Watt Standing and 10k Startup wattage were plenty for our home. that and the Package coming with a Battery and an electric startup were all key features that pushed us towards this brand. we did not have much knowledge in Generators and even less in hooking them up. I love the 25 foot chord it came with and also the ease at which it is transportable via the super heavy duty tires. we went with a professional to hook everything up which cost about 200 Dollars. though I could have probably done it, as the directions were super easy and everything was marked and easily understood, we felt having someone with experience to install it was wise. overall we are very happy with this new model and even happier with the performance. it is not loud (like a Starship taking off) as the exhaust is pretty well muffled. love that feature. we recommend this to anyone with potential power issues.

Easy to assemble

As I have not needed to use it yet , all I can say is it was easy to assemble and started up with the first pull . Love the big gas tank and the wattage will be sufficient to cover most everything needed in an outage . Will be installing an interlock kit . Will have running water but probably no hot water , washer , dryer or stove to cook on .
