Iq3500

At this point I have not used IQ3500 for it intended purpose. Therefore I am unable to fully rate the product at this point However I do have one concern. The lack of servicing dealers and the availability of maintenance kits in my area More to come

Bought today Replacement generator

I bought this generator this morning, to replace my generator that was giving me some problems. Its so much quieter than the generator i replaced. It is lighter. It is also very stylish and pleasing to the eyes. The quality is outstanding. It is easy to start. Its also easy to add fluids. I love this generator! Im so excited to have such a quality product. I live off grid 100 percent of the time. I need reliable, dependable, and easy to operate products. Thank you Generac!

Excellent product. Better than Honda. More features.

The Generac IQ2000 generator out performs the Honda generator. I love everything about it. After looking on YouTube and the internet I decided to go with the Generac. Price is just right. I am a retired Firefighter and First Responder after 39 years. Used all types of generators in the fire service. Thank you again Generac for a great product. Will use the generator for my personal use during storms, etc.

Brand new out of the box and to the shop!

We ordered this Generac generator because of the positive reviews but sadly are disappointed. We had to order two and neither one of them worked as they should. The first one the exhaust blew white smoke and a strong odor of fuel/oil. We followed the instructions in the owners manual. We ran it several times hoping it would go away. It was suggested by Generac customer service to send it back. We ordered a second one with high hopes that this one would be good. However, after prepping it as recommended in the owners manual, the green ready light did not come on. We plugged lesser expensive equipment in to the unit and it worked. However, if the ready light isn't working properly, how do we know the overload and oil lights are working. This time Generac customer service suggested we take it to a certified place of service. So we have a brand new out of the box Generac generator at a service center, never been used. Very disappointing. It's been 5 weeks since we ordered the first one and we have yet to have a working generator.

Lasted 10 hours

Was thrilled to get this unit and did a ton of research before purchasing. I ran this unit for approximately 10 hours and the digital screen stopped working. This was under a minimal load and under normal weather. After I shut it down for the day there was fuel leaking out of the case and onto the ground. I haven't been able to identify the leak but I suspect its likely carburetor related. I am currently working on locating a service repair dealer which is much harder than I thought it would be. The only dealer I have found listed on the Generac website who actually does repairs is 16 weeks out. I might have got a lemon of a unit but regardless its frustrating that there is no great repair options.

I have tried another of small generators and I should of gotten this year's ago

This is a very economical generator good power with excellent fuel usage. I uses for portable power when I am traveling for work. This is one of the quietest generators I have ever had and used in the portable line. I definitely recommend this generator if anybody is looking for a small compact generator that is very easy to move and very portable. This is a replacement generator for a much more expensive generator that if I'd known this generator was as good I would have bought this generator and not had spent the $2,000 on the other generator that I am still fighting for under warranty

Quite and powerful

[This review was collected as part of a promotion.] Great generator... super quiet and very efficient. It is a little heavy, Runs great, quiet, well made. Be very careful to follow the starting instructions in the operators manual and you will be happy . This generator is so easy to start, and it's so quiet while running. . Never worry about a storm or power outage again. What a quality generator by Generac!!

Good things come in small packages!

We have lived in the same older home since 1970 and it has a perpetual wet basement. The sump pump runs MANY times during the day. Just recently the electricity was off for several hours 2 times within a week. After struggling to get the old generator in position and operating we decided enough! We needed a more portable generator that was lightweight and easy to handle. This one fit all our needs. It is really quiet and has two outlets which are enough for our basic needs. Really like that it shows how much power it is using for operating the sump pump to see what it is left to use for something else.

Guage required for 50ft extension

I need to connect the 2200i to 50ft extension cable to run fridge/ freezer & tv & some lights from one of the standard plug sockets. What guage extension cord do I need? Can I run second extension cord off the first, or do I need to get another 100ft extension cord for the other plug on the generator so I can also run tv & lights - as circa 50ft away from fridge. Struggling to work this out before I can test generator. Thanking you in advance. Will update rating once I can use generator.

IQ3500

I just purchased a IQ3500. The unit came with everything needed less the gasoline. I read the manual and filled the unit with the provided oil, added 100% gas and fired it up. It started immediately and ran great. Ultra quite and very smooth. I plugged in some lights for a lite load and ran it for 1.5 hours. I shut it down and checked the oil level. I am very happy with my purchase. This is my second Generac generator that I own. My older one is an 11 year old 7500 watt and still runs like new. Thanks for building reliable products!
