This product has the right features for the task at hand!

I've just received the generator last week and have tested it for about 10 minutes. It worked perfectly, but I'm yet to test it out in case of a loss of utility power over several days! Since I selected this model, I feel it will come through in powering up the essentials of the house with no problem.

Easy to maneuver

[This review was collected as part of a promotion.] Works great. Took it on our latest camping trip it ran our site and our neighbors site with power to boot. Quieter than I expected! I liked the idea of never flat wheels but they seemed a little bent. Handy fold up handle that was well balanced and easy to maneuver was a bonus.

Quality Is Number 1

I purchased the Generac GP8000E after doing alot of research with several other brands. I am not disappointed, from the moment I started to unpack the generator I noticed the quality of the packaging, which gave me confidence in the product right off the bat. The engineering made assembly very easy! You notice the quality in every part as you put this baby together. The quality shows that Generac and its associates genuinely care about the product they put out to the consumer.

Solid Heavy Unit

I bought this unit last year to run my new 24 ft. concessions trailer G-Dub's Grub which I opened 2 weeks ago. I have worked 2 large events with 20 hrs on meter. It runs the 30 amp service easily-- lights, water heater, water pump, fridge etc. All filters, oil drain, spark plug easy to get to, which is a big reason why I bought it. Getting ready to change to Mobil 1 10W-30 synthetic w/ extra Generac filter sent with unit. I use 89 grade non-ethanol fuel. Multiple power options here folks. Heavy USA made unit. My problem with this unit is it's too heavy for me and staff (female) to handle 390 lbs. Overkill on my part. Just bought extended warranty plan last month. Weighing my options.

Competition cannot touch product features for the price!

I've owned three generators in the time I've resided in my current home for 27 years. My previous brand also contained a Generac generator module, still functional after 15 years! My new purchase of a GP7500 was based on my previous experience with Generac. I have nothing but good words for Generac as it has prevented numerous flooded basements, loss of food in refrigerators and freezers and comfort with running water, heat/AC and lighting for my family during days of power outages.

Life changing & peace of mind

[This review was collected as part of a promotion.] I’m so grateful for this generator. I live in NJ, on the shore, & have dealt with hurricanes. This will help save food in the fridge & can help keeping the house cool, if needed. At the very least charge devices so we can be in contact with family, if needed. It’s not too loud, & super easy to set up. I’ve wanted a generator for so long so I’m so happy with this!!

This is a great generator!

Come January 2021 this unit will be one year old.Every three months we charge it for 24 hours.When ever I go out and start it up THERE are no problems what so ever.I like to run it ever so often so I know all works find.We are lucky that we have not needed to use it for a back up yet!!You see we live in Northern Ontario Canada where we get lots of snow and very COLD weather! I know if and when the time comes this unit will stand up to it's job.

Wanting a generator for years

Being a new home owner I always thought about power going out. Well power went out! Went to local hardware store many different options I’ve heard from other people generac was top of the line a little pricey but well worth it. Will recommend to anyone I know

Quick Start, solidly built

I live in the Northeast corridor and have decided this wacky weather is no fun w/o electricity. Purchased the GP6500E w/ manual transfer kit. Assembly was easy. Started right up w/ the electric ignition. Contracted a local electrician to install the transfer box. Straight forward and no surprises, other than needing a 60 amp main breaker. Electrician commented on the box and said the set-up was pretty slick. Prepared and waiting for Mother Natures next haymaker.

Great features!

[This review was collected as part of a promotion.] I received this generator free as a trial product and honestly wasn't expecting much out of it since it was free. I was very wrong! This is by far one of the best generators I've ever used!! The power is beyond belief. It has several plug ins and could potentially power everything I would need in a power outage. I wouldn't hesitate to take it camping, use it in a garage, the possibilities are endless. I cannot say enough good things about it!
