Solid Generator

Would Recommend

My generator has worked flawlessly since I purchased it. Unfortunately I have been unable to get it to work as I had intended, which is to run my pool circulation pump during winter power outages. I have verified through multiple electrical experts that my connection from the generator to the pool equipment is correct. My next step is to adjust the Hertz output down to 60 from the 62 it is currently producing. Any direction you can provide me to make that adjustment would be sincerely appreciate...

Didn't even get a chance to use it/ it failed.

I bought this new generator new in the box for our deer camp. We unboxed it and added the oil and clean gasoline and started it. It was gushing gas out of the carb so we had to shut it down. When we called Menards to bring it back for an exchange they said that they don't take them back and we had to bring it to a certified repair shop that was 75 miles away from our camp. Needless to say, we didn't have a generator for deer season because the repair shop was booked. When I picked it up the owne...

Overall, very good quality and features.

Would Recommend

Just bought this a month ago and haven't had the need to use it yet. But I did have to assemble the handle, wheels, add oil and gas and start it. My review is solely based on that. The wheels were relatively easy to assemble, keeping in mind that the machine is heavy and you will need to lift it on blocks, or use a helper. They give you a perfectly shaped funnel to add the oil. Don't lose it. The handles are easy to install and conveniently fold down when not in use. They make it very eas...

Will run the whole house.

Bought generator on Amazon black Tuesday. Still breaking it in. Electrician said it was a good product. Starts easy with on or two pulls . Hope I never have to use it to run the house but if bad weather sets in I will be ok.

[This review was collected as part of a promotion.] Super durable and handy. We have a winter storm coming and I feel totally prepared because we have this thing! It is super heavy and we keep it in the garage.

Nice generator

[This review was collected as part of a promotion.] This geneator will be great when we are boondocking with our RV! It requires gasoline which is a minus for me because of the smell but at the same time, it is easy to find and purchase. This is a very heavy item, and you will need a friend to move it around!

Quality Generator

[This review was collected as part of a promotion.] The Generac 5500 generator was very simple and easy to put together. Adding oil and fuel easy as well. Start-up with manual startup was fairly easy. This unit also comes with a battery for an electric start which is pretty cool. The load can handle several small appliances such as a refrigerator, freezer and a TV or you can use it to run a single 220 volt HVAC system by itself. Moving the unit is a breeze as it comes with a handy handle that fo...

Solid, well-made unit.

This generator is everything it claims to be. Easy to set-up, use and is reliable. I hooked it up to my home for a test-run the day after I received it. It started up instantly and powered the entire "critical function" sub-panel in my home (HVAC, water/well, freezers/refrigerators, water heater (gas), water softener, garage door, washer/dryer (gas), WIFI/network and critical lights/outlets). We built our home in 1998 (just prior to "Y2K", ha!) and included the sub-panel. I toyed with the ide...
