Great unit with Excellent customer support

bought this unit, and had a major issue with it before it even had any hours on. I contacted customer support and had the issue resolved with one phone call. They sent out the parts right away, without any problems. now the unit runs perfectly. very happy with this purchase.

Asset That Everyone Should Have!

[This review was collected as part of a promotion.] This is an indispensible asset to our household. Southern CA can be very unpredictable and this is our safety net for our family. It is well made and easy to move with the wheels. So glad we own it!

First Impession not good, Sence then perfect

Bought this generator as a home back up. First use was a long term power outage in cold weather. After 17 hours it pushed the little gasket/bushing out of a fitting where the two wires go through the crank case for the low oil sensor, It puked all the oil out of it on my driveway until the low oil sensor shut it off. Not good at 2am in 5 degree weather. In the dark I thought it blew up with all the oil. Diagnosed it the next day, pushed the bushing back in place with silicone sealant. Sense then it's been perfect. I like the generator now but at 2am the first use I was frustrated. I would still recommend this generator as I think this was a fluke and it's been perfect since

Was a lifesaver when needed.

A derecho came through our city on August 10, 2020. Severely damaging the power grid to the city. I purchased a RS8000E the following day. I needed the unit to run a refrigerator and freezer, but more importantly my mothers oxygen generator. We were without power for eight days. The only issue I had was with the user manual no specifying that flipping the 30 amp circuit breaker need to be turned on to activate the two 120V outlets. I figured it out and had no issues with the generator. The generator definitely paid for itself. I would recommended this unit to anyone.

I bought this during hurricane season since my other generator did not put out power anymore,it started great but shut down 15 min. later, I can restart it, but it kept shutting off every few minutes. The CO2 sensor is just too sensitive. You can’t have it near anything pretty much out in the open. It’s kinda hard when it’s raining and you can’t even run it under a tarp other than that, I guess it’s a good machine. Hopefully it will start up for me next Hurricane season, I would give it a five star if there is a way to disconnect that CO2 sensor and not void warranty

Excellent product

After much research I waited a little too long to purchase this generator as we had a power outage at 9:30 pm but at 11 pm I had the house up and running the store was 20 minutes away.The unit did every thing I expected and more.My family was very relieved as I had every light in the house on 2 freezers ,fridge and sump pump I had already set the house up for generator use so after assembling generator it was plug in and go.The outage lasted 6 hrs then 2 days later power was out again for 4 hrs did not miss a beat I hope I do not need it again but if I do the security is worth the price alone.

Has all the features to keep our lights on

[This review was collected as part of a promotion.] Glad to have this Generac 8000 Watt Portable Generator on hand and ready for the bad weather season. We just bought our home in a very windy/snow-laden area and having a back up generator is the way to go. It took a few hours to assemble and we found that we needed to go get an additional cord, but once we did that, it started up without issue. The built in maintenance timer is great - makes it convenient to know when to change the oil, etc. The wheels truly are heavy duty. We're feeling confident that if we need it, we'll be able to keep the lights and power going for our kids without issue.

7500E Portable Generator

Excellent quality and great reputation is what led me to buy this generator. I am thankful I have not had to use it, however it provides a great piece of mind knowing its there if need be. One piece of advice I will give anyone purchasing a generator, secure your garage. My first generator was stole within the first two week of purchase. Since then we had anchors installed in the cement and have it chained down. We also have a place secured by the house if we ever need to use it that we can secure it to.

Excellent generator.

This generator came well crated and delivered on time. I was impressed with the ease of start up and was amazed at the included maintenance kit. (extra spark plugs, plug wrench, primary and secondary air filter, oil filter). I have not had a chance to power the entire house with the unit but it starts easily and runs strong. Although I do not look forward to a lengthy power outage (which has been more frequent lately in my rural setting) I feel much more at ease having a well built machine as a back up.
