Rated 5 out of 5 by from You get what is advertised I decided that going without electricity and having the basement flood after the last hurricane was more stress than I wanted in my life. I did a lot searching on the internet for a generator that would give me the best peace of mind. I settled on the Generac 5940 GP6500- 6500 Watt Portable Generator (5940). I paid for the tail gate service and it was delivered very promptly and wheeled up to my house. Assembly was extremely easy. I put oil and gas in it as directed, and with one pull it was running. A few weeks later I had the "Transfer Switch" installed and we killed all power to the house, started the generator, and flipped the transfer switch to the operating position. Everything we had connected (which was just about everything except central air conditioning) was powered on. We even ran water until our well pump turned on and the generator never even hesitated or appeared to be under strain. So if we ever lose electricity again, especially for a long duration of time, the neighbors will see that we have heat, water, and lights. They will all be welcome! Thanks Generac for supplying a product that truly is what is advertised. In today's world it is nice to see some honesty in advertising.

Rated 5 out of 5 by from Great generator This generator powers my entire house including heat pump, all electronics including a gaming PC and laptop and oven when the solar panels aren't producing power. I'm not fond of the Cosense but it's still well worth the money.

Rated 5 out of 5 by from Security Purchased after 43hr outage in blizzard. Easy to manoever and good plug selection were sellers for me. Starts first pull. Hasn't been used yet but feel confident it will do the job. Here with no power we have no heat or water.

Rated 4 out of 5 by from Quality Unit Returned Chinese made product not satisfied with. This replaced it for $100 more and works 100% better. Quick assembly and start on first try with easy electric start. Thats how it should work. Like the looks and design quality and components.

Rated 5 out of 5 by from Buffalo, NY Christmas Blizzard Have a 5000w Coleman Powermate that I started at 8:30AM Friday 12/23 when the power went out. Didn't have it covered and after 2 hours it was coated with snow and ice and died. I purchased the GP3300i for use with a travel trailer and am glad I had it in the garage. Took it out back and ran a heavy cord through the garage and into the house. Ran it 3 to 4 hours at a time, rest it for a while and start it up again. Powered the refrigerator and freezer one at a time. Total of 28 hours, it just ran great the whole time. My wife found a plastic tote that would fit over it which I lifted on blocks a few inches off the concrete so this one wouldn't suffer the same fate as the other generator. Would definitely recommend this unit, and Generac in general.

Rated 5 out of 5 by from Finally was able to use my GP17500e I purchased this generator new approximately 5 years ago. I left an initial impression review at that time. Other than monthly test runs, I have not had to use it. Last night it was finally used to provide power for the entire house. It worked flawlessly. It was 28 degF. When I started the generator and it ran continuously for 16 hours with no shutdown. Temps got to a low of 6 degF. It’s one thing to lose power in the summer. Losing power when it is in the single digits is an altogether different scenario. Our house has baseboard electric heat that had to work in some rooms not heated by the woodstove. In conclusion, and as a follow up,after five years it did exactly what is what purchased for.

Rated 5 out of 5 by from New owner - early review Cabin without power for days, zero degrees outside. Bought our first generator ever. Excellent packaging, mostly assembled, only need to put feet, wheels, and handle on. Built of sturdy materials. Oil needs to be added, but included. The 30w included wasn’t for our temperature range so bought some 5w-30. The instructions don’t say how much, so we put in the same amount as the included bottle. Oil fill port is hard to reach, but they include an awesome funnel. Suggestion: Please add oil volume to directions. Assembly was straightforward, all necessary parts were in the box. Need a few common tools. Controls easy to understand. Put some gas in. Speed, choke, and fuel shutoff valve straightforward. Started on the first pull. Easy pull was enough to turn it over. Ran smoothly. Shutoff instructions straightforward. Impressed with the quality and easy of use. Definitely happy with our purchase. An additional plus- almost to the minute, as soon as we turned off the test run, we got word that the power was back on at our cabin, after 5 days. Awesome.

Rated 5 out of 5 by from A portable beast When I decided to purchase my generator, I spoke with a fellow instructor at the JATC. The company he works for is an authorized dealer of Generac and he understood my needs, as my home doesn't have natural gas nor a large propane tank. This generator is basically a whole house generator on wheels but uses gasoline. Assembly was rather easy with basic tools but a friend to help is recommended due to the weight of the unit. Speaking of weight, maneuvering is easy with the large pneumatic tires. Once the fuel system was primed it fires up a moment after the start toggle is pressed. The fuel tank is large, most small cars don't even hold 16 gallons, buy several 5 gallon cans as they are easier to lift/transport. As a licensed electrician I did the install myself and chose not to install a transfer switch but used a main breaker lock-out on my panel. As it sits the generator is not AUTO transfer switch ready but any good electrician could void your warranty and make it work...lol. For being all electric I have a light load of only 44A max per leg and the GP17500E doesn't even bat an eye. Summary.....have basic tools and a friend to help. Higher an electrician to install the proper legal hook-up means. Buy several gas can and rotate the fuel often. Very satisfied with everything.
