4 out of 5 stars review

voltage fluctuates too much.

Product runs well right out of the box but I am concerned about using it on many items or long term. I am currently running a steady 1000W when our 1hp well pump starts the voltage will drop to 30V then spike to 159V. We didn't have this problem with our old Pramac 7500W generator but it only had a couple hundred hours on it when it quit. We needed a new one for water and this the only one available. Can't afford to be out of water for our horses or I would consider returning it for a better one. But have no idea how long that would be.

Excellent value

Just got it. started perfectly without any issues. Easy to move around. Everything as advertised. Have not used it for power yet but have high expectations. Not nearly as noisy as i thought it would be. Not any louder than the poulan pro 6600 which it is replacing.

Great Product

This generator fit our needs perfectly. We have a small farm and needed a sizeable unit to power things when power is out with affordability. This unit is large but easy for my wife to move around. It is very easy to operate and quality is excellent.

Amazing

[This review was collected as part of a promotion.] This Generac Generator is amazing!! We live snack dab in the middle of Florida and get so many hurricanes each year. This powers most of our home and runs for a long time. Highly recommend this generator!!

Two critical FAILURES during 11 day outage!

I purchased the GP1800 to power a natural gas forced hot air unit. After losing power during hurricane Sandy, I used it for most of the first day and night to keep my wife and child warm. I returned home from work to find that the recoil starter assembly had failed, causing the recoil assembly to spin with the crankshaft of the engine, effectively destroying itself. I was able to remove the assembly and start the unit with a length of para-cord. On day 7 of our outage, only using the unit for approx. 6 hours per day to alternately power the heat and 2 refrigerators (individually), the unit just stopped working. The engine had seized, crankshaft unable to move at all. Oil level was okay and was checked every morning before start-up. Hopefully warranty service will be able to repair or replace unit!

Saved New Family

I live in the Suburbs of Buffalo where the winters are awful. I bought this Generator as protection for my family when we needed it the most. We lost power for almost a day, my new family, including my newborn son were able to stay warm. If you want a Power House of a Generator, that can run Fridges, Freezers, light stoves and ovens, and keep the heat on! This is the BEAST - I mean, best to get ;-) Running a Fridge, Freezer, Furnace, and several lights and Electronics, gas lasted 6 hours. Unit has 5 gal capacity. Rule of thumb is an hour a Gallon to be on safe side. I am a Generac Customer for life. GP8000e with COsense is an amazing unit. Thank you.

Works great as expected

I had an old generator that needed replacement. I looked at several but the 7500e seemed to fit what I needed and I had heard good things about Generac. It has electric start and kicks over immediately. I plugged it into the house and tested it with no problems. If I loose power, my basement could flood and in winter can get really cold so now I feel much more secure that I can power whatever is necessary in the house in any season. It is a bit loud by I can live with that in an emergency.

Couldn't ask for more

[This review was collected as part of a promotion.] In the brief time we’ve had the GP 8000E, it has worked flawlessly. The unit arrives well packaged and protected and mostly assembled. I had to install the wheels, handle, battery cables and fill it with oil (included). A layperson could easily do this but it helps to have a partner to lift the unit to put the wheels on. The machine fired right up with both the electric start and pull cord and worked as advertised. For my application, there are plenty of power outputs and it’s easy to understand the control panel. The machine seems very well built and there aren’t any obvious quality shortcuts. I haven’t had a chance to plug in the battery charger but that’s a nice touch so you don’t have to buy a separate battery tender. Competitive price, well-built unit, intuitive controls – what more could you ask for?

Easy to assemble, great sturdy quality, and started on the first try

I have been wanting and researching a potable generator for years. With this, the generac name continued to rise to the top in quality and performance. Then came an immediate need, and after looking at my options I decided to go with generac. Even though the decision called for a quick decision I was confident that I was making the best decision. I found what I was looking for at Lowe’s and actually upgraded from a 6500 to the 8000, the price was right and it came with an electric start. I brought it home and within 2 hrs had it making electricity! The ONLY down side of the whole situation was that they advertised that it with idle control and it turned out it didn’t. Please correct this. I give this product two thumbs up!

Generac GP6500 saved our groceries!

September 11, 2017, Hurricane Irma headed to Georgia! We lost power at 7:30 a.m. that Monday morning and power was not restored until 11:30 a.m., Thursday (Sept. 14th). Seventy-six hours without power, but the Generac got us through it comfortably. I've never had/used a generator before, but it is easy to start and fairly simple to use.
