Realibility

I bought this generator because of its realizability. We lived in NJ, during both hurricane Irene in 2011and hurricane Sandy in 2012. In both storms we relied on a Generac generator for solid performance for over two weeks without electric. This was huge, as we owned a dog kennel in which we were able to keep going, helping a lot of our customers care for their pets. Tom

Super quiet!

Bought this portable for my camper as a backup and for state parks where there isn’t any electrical hookups. Went with Generac because i also have a 17KW on my home. Excellent brand! I was surprised by how quiet this guy is. You walk 10 feet and it is like its barely audible. I recommended it to my friend who was looking for one. He bought the same model (iq 3500) and he is also thrilled! I can highly recommend this generator for performance, affordability and looks.

Not worth the price

Bought this last year and was disappointed it wouldn’t run a small ac. It will start up and run for a few seconds but then goes into limp mode. Won’t run a toaster or microwave without going into limp mode. My old Honda 2500 ran it fine. It hardly idles with no load. Tried to return but couldn’t. Told to call generac which I did several times with just the runaround. I basically use it to charge the trailer battery. Haven’t found anyone who can make it work as advertised

Very adequate as a home backup

I purchased two 3000i generators as emergency backup power for my home and my daughter's home. I wanted to run emergency power for two refrigerators, one freezer and outlets in my office for tv, computer, usb charging and minimal led lighting. I hired an electrician to install a sub-panel and inlet for the generator to handle the 4 circuits I wanted to use. I checked the power needs for all the appliances. Since it weighs 60lbs I bought a cart for it and it is very easy to move from the garage to the outdoor sub-panel. All I have to do when the power goes out is to turn off a 50 amp breaker in the main and sub panels, turn on a 30 amp breaker in the sub-panel, plug in the generator and turn on each of the four circuits one at a time to make sure there is no overload. We tested the generator over a period of an hour with all four circuits on. It worked great and surged only slightly when one or more of the appliances cycled. The cost for parts and labor from the electrician was about $1000.00. I strongly recommend a professional installation. You can have serious problems if not installed correctly. It is comforting to know that our families food supply is protected and our communications equipment will function during a blackout. To accomplish all this the generator would only need to run 4 hours a day when the monitors on the appliances show a need to cycle. At a 50% load that is only 1 gallon of fuel per day. Communications equip. would be used in that 4 hour window. I found the build quality excellent. The only change I would make is to make the oil access door bigger and smooth the edges of the opening. It is difficult to get a big hand in and remove the oil fill/check plug. It started first pull and ran very smooth and quiet.

Unbelievably quiet!

After doing lots of research online I chose this generac model and have not been disappointed! It is incredibly quiet even under load. The efficiency mode is a nice option for lighter loads to conserve fuel. The only issue I have is the generator is a bit heavy for one person but can be managed if necessary. A wheel kit would make it about perfect if one were available. The electric start is a great feature and pull start is not difficult if needed. Started right up out of the box and have had no issues, it runs the ac unit on my 32 foot travel trailer with no problem. Highly recommend this model, quality well built generator as the ne would expect from Generac.

This dual fuel generator is a must for every home.

[This review was collected as part of a promotion.] My power goes out way too often due to trees breaking during storms. I have lost so much food as a result, so this generator will be a game changer. At over 115 pounds, it is heavy, but the compact size and wheels make transport easier. With four different power outlets, it means I can plug in appliances, cell phones and lights during an outage. Running on two types of fuel (gas and propane) gives me flexibility for usage. I like the LED display to see the output and gas consumption. Generac is a brand I can trust because they have a great reputation.

I'm an architect and I specify emergency power for big projects

This product provides a thoughtful balance of power, economy, and ease of use to solve the problems of power outages and day trips to places without power. It is not a construction generator but will let you run consumer tools one at a time. I use it to run my coffeemaker OR my refrigerator during power outages. In addition you can charge your stuff and run a bunch of LED lights.

Amazing product

[This review was collected as part of a promotion.] Powerful, Reliable, and Easy to Use! The iQ3800 Dual Fuel Generator has been a fantastic investment for our outdoor adventures and emergency backup needs. It’s incredibly easy to start with the push-button electric ignition, and the included battery means no extra purchases or setup headaches. I love the dual fuel option, giving us flexibility between gas and propane depending on the situation. The Economy Mode is a nice bonus — it helps reduce noise and saves fuel when we don’t need full power. The LED display is clear and helpful for monitoring fuel levels and output, and the COsense® safety feature gives us peace of mind, especially around the family. With sturdy wheels and a solid handle, it’s surprisingly portable for its power capacity. Whether it’s for tailgating, camping, or job site use, this generator checks all the boxes. Highly recommended!

Everything I expected

I recently purchased this generator first to supply power for tools to build a bunkhouse. Second I would like to use it to power the bunkhouse when I stay in it. So I started on the bunkhouse last weekend and put it to the test. I’d say it passed. I ran a small compressor for a nail gun and a miter saw mainly. At first I ran a compressor that was at the maximum amperage the generator allows. It overloaded the generator and it shut down. I wasn’t upset. I had a smaller compressor available and used that. So I was actually happy that overload protection did it’s job. After I let it cool down from the overload I fired it back up. Ran fine the rest of the weekend.

Good but poor enclosure

This little generator is awesome, very quiet Powers more than I expected it to. The major downside is the fit and finish. The front of the enclosure is broken I contacted generac to purchase a new enclosure or parts they referred me to the retailer the retailer referred me to generac. So I've gotten nowhere I've sent emails and pictures. Besides the cracks and the enclosures the generators awesome. Generac contact me hook me up please.
