Super quiet

Just bought and made a testing. Pros: Easy setup. Easy to start. Super quiet! If you turn the corner of the house you almost do not hear does it is running or not! Verify with different loads (from light up to 2 kW) Not really a Con: Wheels absences! Generac, please add an option to buy a wheels kit for your very good iQ3500! Why a customers should play a game with Honda Wheel kit, Caster's wheel kits and so on? I feel ready for power outage and highly recommend this little generator for exactly the purpose we used it for, which was to keep essential appliances running through an extended power outage.

Louder than expected

Heat shield over the muffler rubs against the muffler and is loud and annoying. I'll probably take it off and see if I can bend it away so the metals don't touch each other. I bought the generator to camp with so I want to make it a little more quiet. Haven't gone yet. Just filled the oil and put gas in it to test. Ran a heater and skill saw with no issues.

Not impressed

First weekend out with it... first use it wouldn't run write and it spent 2 1/2 weeks waiting on the warranty guy to get approval to work on it and see what the issue was. Just got it back hoping it works this weekend otherwise it's going back to the shop

Powerful and practical!

[This review was collected as part of a promotion.] I'm so happy with this generator! It takes up less space than I had anticipated and is easy to store. It weighs just over 100lbs. Living in an area prone to power outages and wildfires, earthquake threats etc, and caring for animals requiring me to access to power at all times, it is really practical for me to have this on hand! It delivers exactly what I need, performs how I want without excessive noise, and doesn't waste fuel, which is a bonus!

Nice unit, but difficult to start

I have older version of this unit (G0071171). It was difficult to start when we first got it , but has gotten worse with time. Now, even when unit is sixty degree range it takes 16 pulls of starter rope to start the generator. It has less than twenty five hours running time on it.

Customer Service and Warranty issues

I bought this generator after doing my research and wanted to get one with a great warranty and a company that would stand behind their product. I got neither. Long story short had an issue with the generator after initial break in process. Oil was coming out of the top end and most places where it shouldn’t be, I have it well documented. Took it in to certified retailer to get warranty work done and Generac refused to pay for a dime. I have had issues contacting their customer service reps and so on.

Great product

I tossed around the ideal of getting a portable generator so I wouldn't have to lug around my other larger ones. I was convinced that the Honda eu2000 was the best and quietest on the market until I started reading about the Generac iq2000 and watching some videos. I just couldn't make myself spend 900.00+ for a Honda. So I purchased the Generac iq2000 last week. It arrived extremely well packaged, with manual, engine oil and funnel. Added the engine oil and some gasoline and it fired right up. This unit is quiet !!! performs well and I love the features it has. Well done Generac !!!

Great product for us Over The Road truckers....

Hello.....being new as an OTR trucker, I discovered that even with the truck's already installed 1800 watt power inverter, it does not last long enough when one is parked for at least 34 hours, while completing what's known a 34hr reset (a new 70hr On Duty clock is then given). On a very hot/cold day, with the A/C-Heat being on and at its lowest settings, with a TV, satellite dish, and an external hard drive (to record programs) plugged in, the truck will begin to shut down non essential items after about 12hours, such as the lights inside the truck, and the refrigerator (refrigerator is non essential??!!), and if long enough, when turning the truck on to juice up the truck's batteries, it will cut power completely to the inverter for a brief moment, that's a sure sign the truck's resources are getting very low. So, I decided to look into a portable generator, and after looking at and looking in depth at many other brand's details, this Generac IQ2000 caught my eye. I really liked the gauges it had showing, that is very convenient, I felt the 1600 watts was more than enough for my needs, those items mentioned above does not even register the 20% load indicator, and usually will show close to 13hrs remaining. I can even plug the truck into this generator to help juice up the truck's resources if need be! MInd you, this will probably not charge up the truck's auxiliary power supply, which runs the A/C and Heat, but once those have extinguished it's power source, i can then run a cooler or heater inside the truck, that's a big plus! I think, in my opinion, this company should direct its advertising to us OTR truckers....this is a great product.....Home Run!!!!! Chris.

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.

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.
