Good product without much support or info

First off I won this in a raffle, so there is nothing to complain about. However I would like to point out a few things that I feel could be done better by Generac. First off, there are no break in instructions included with the generator. I assume every small engine needs a break in period so I had to look this up myself and perform it. Secondly, why no wheel kit? Yes it’s kinda light but would a wheel kit be hard to make or sell? Sure would be handy, so I’ll have to make one myself. Third, it was quite difficult to find where to register the warranty. You really have to search to find it.

Part of My Readiness Plan

As a resident of earthquake country, and a member of our local Community Emergency Response Team (CERT), I needed to complete my preparedness kit by adding a home generator. Unlike other users who have reviewed this model, I am not a camper, I don't regularly need portable power for tools, nor do we have an unreliable power grid. However, I don know what will happen when we have a large earthquake and that power will be unavailable for days, perhaps even weeks, following such an event. As a CERT member, we practice for such situations all the time and I have seen plenty of portable generators in use during these exercises. I'm impressed by the cost/benefit ratio of Generac and trust that the IQ series will be just what I need for my home. I regularly run it as part of its maintenance schedule, place an electrical load on it, and am very satisfied with its performance. As I live in a townhome complex, my neighbors appreciate that it runs quietly.

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.

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

Does not provide output power matching specs

This generator is supposed to deliver 2200w running power but we have found it automatically shuts down when we connect a load of 1700w. It does run well with a load of 1300w. The size and weight of the generator is great and it doesn't make too much noise. The run time is rather short due to its small size so limited capacity gas tank.

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.

Primarily Backup

We grew tired of our what seemed like twice monthly power outages-can anyone say aging infrastructure. I researched several generators and one constant was a brand name with a good reliability rating and one that was not out of reach of our pocket book. I picked a Generac non wheeled generator that is semi portable to me(75 lbs is semi for me).It will sit on a cart in our outdoor shed-where I can run it with the doors open. I installed a Reliant Generator through the wall outlet kit that allows running the generator while all our windows and doors can stay shut(hidden Cords). 3 pulls of the recoil is all it took for initial starting out of the box-and ran very steady. Now we can run a portable heat/AC unit if needed along with our other refrigeration and freezer. I need something that was large enough to run a couple of appliances at the same time and this generator was of sufficient amperage and voltage. We are very happy with our choice and after testing out it kept up quite well. Quiet and sufficient power for our needs. We're happy.

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

Great new iQ model to the lineup!

Great new product from Generac. We also have their other iQunit, iQ3500, which we use for camping and other needs but needed something with more functionality and ability to connect to our LP tank which this product solves our need. Super quiet, easy to start and move around with the added wheels vs the prior model.

An almost perfect generator

I bought 2 of the Generac GP3000i generators. Both are very, very quiet and easy to use. I can run our RV air, refrigerator and charge a golf cart at the same time on a single unit, but I like the parallel kit when I need a little more. I wish there was a way to do an extended run fuel system to get longer run time between gas refills. I think at this price point it should also have a built in hour meter. The little door at the top to access the spark plug flies off of both of them when it is in the bed of my truck and should really be better designed. One of the generators has less capability than the other and goes into fault mode randomly. We will see what customer service is like to correct that issue. I would buy another one if I needed it.
