What Customers Are Saying

Customers overwhelmingly praise this generator for its exceptional safety features, reliability, and ease of use. Most highlight the CO-Sense technology that automatically shuts down when carbon monoxide levels spike, combined with low-oil safeguards and hour meter tracking. Reviewers consistently report first-pull starting, continuous multi-day operation, and 12-14 hours of runtime per tank, powering essential appliances reliably during extended outages. Many appreciate the intuitive controls and minimal assembly required. A few mention concerns about the short power cord and isolated issues with frame welds or fuel leakage, but these are vastly outweighed by strong overall satisfaction.

I bought this generator after a storm and fallen tree caused an extended power outage in our neighborhood and my old generator wouldn't start. This Generac really stepped up to the task and I was able to run just about anything we wanted in the house including two 220V AC window units and two outside security lights and it never missed a beat. It ran almost 12 hours on a five gallon tank of gas which impressed me (better than my old unit). Love the features like electric start, auto shutofff wit...

Lasted 1 week

Would Not Recommend

We purchased this generator 1 week ago when there was a severe weather event in our area. It didn't run a full 7 days. Woke up in the middle of the night to no power went out to check the generator and all of the oil was out of it on the ground and we later found that the engine had cracked. Generac was not at all helpful but Lowe's was. Lowe's gets a rating of 15 out of 10 and Generac is 0 out of 10.

Works Great - Emergency Shipment

Would Recommend

I debated for years about buying a generator. Power outages don't happen often where I live, but they happen just enough to make you think about having one. Recently, a severe storm rolled through our area and left us without power for four days. That was finally the push I needed. Fortunately, my local Lowe's received an emergency shipment of this generator. I ordered online, selected curbside pickup, and the store team loaded it directly into the back of my SUV. The setup was simple and took ...

Never again

Would Not Recommend

I will never own another generac anything. Lost power for about 7 hours now. Came home wired it to my panel, ran for 4 hours and now nothing. Only owned it for a year and if that’s all you get from it for $1000 it’s 100% not worth it. What a joke of a company

This was purchased due to power outages. The assembly went well but it was tricky for this 78 year old to maneuver the weight. I was most impressed by the staff guy at the store who loaded it into the back of my vehicle without scratching anything. We haven’t been able to actually use it yet. The power has not been interrupted since assembly and start up. I hope we never need it!
