Excellent portable generator

After months of extensive research, I chose the Generac IQ3500 as a home back power source. All of the pre-work paid off. This unit is very well built, runs extremely well, and is unbelievably quiet. Could not be more pleased with this generator. Well done Generac.

Excellent and can be better.

I am a event rental company owner. We rent generators for many different applications. Purchased us to run our restroom trailers which have RV generators. What we really liked about it is that one person could move it. It is very quiet. We would love to see this with an EFI option.

Great Unit!

I wanted a quiet unit that would power several items while doing BBQ competitions and events. I am very happy about how quiet this unit is and it has more than enough power to run all my equipment. I was also pleased on how easy the pull start was on this unit. I would gladly recommend a GP3000i to anyone looking for an inverter generator.

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.

Amazing generator!

[This review was collected as part of a promotion.] This generator is solid. It’s excellent quality, is made by a brand that I trust, and you can tell by the quality of the materials, that this is built to last. I did receive this complementary, however, it has no bearing on my review. I am very pleased with this product, it really is great and well constructed. Grateful for camping and practically any use. I highly recommend it. 5 stars!

Generator

[This review was collected as part of a promotion.] Generac Power Systems iQ3800 Duel Fuel Portable generator is very durable. Has a quite noise level. The push button on/ off doesn’t work. It may be the battery, but pull start works great. Easy to put oil in and maintenance is very easy to do.

New Unit Tested By Hurricane Ida

I bought two of these units for construction work but did not use them until Hurricane Ida. I used one and it's quiet and worked flawlessly. I used it for about a week nonstop. The power lasted about 8 hrs per tank full. I powered a house refrigerator, washing machine, several fans and computers. I did buy the inverter generator parallel kit to tie the two units together to supply 6000 but did not need it yet.

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.

Good generator but..

This is a good little generator, but the only thing I have a problem with is that there is no fuel cut off valve. The off/run/choke switch just turns the generator off and does not run the generator out of fuel. I’m thinking as far as storage. I know the manual talks about fuel stabilizer, but I think a fuel cut off valve would be great. I have owned a few generators in the past and all had a fuel cut off valve to run the generator out of fuel when not in use. I have never had an issue with my other generators, but this is a concern for me.

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.
