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.

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 !!!

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.

Love It !!!

I purchased this portable generator for use around my farm and as a power source when camping. I was pleasantly surprised at how quite it operates and the Fuel Gauge, Time to Run and Power Usage read-outs are wonderful. I removed from the box, put in oil and pulled rope twice to make that initial start. A big plus is my wife likes it too. Great Product, Excellent Reputation, Top Notch Quality

Perfect size

This generator is a perfect size for small projects I work on in my shop. We have an RV and will most likely use it for any trip we may plan. We just purchased the generator today. I have only used it for a small project. I was pleased with it and really liked how quite is was.

Very impressed with quality of this product

I ordered the GP3000i. I had not actually seen one in person. It showed up on my door step earlier than what had been projected. I am extremely pleased with the appearance and quality of this product. Started on first attempt. I will be using for home back up and my RV. My main concern beside reliability was portability. I couldn’t be more pleased. Thx

Got it done

I bought the 3000. Lived off it for a few days after hurricane Sally. It powered the full sized refrigerator, an electric cooktop, television, surround sound, phone/laptop chargers throughout the entire power outage. Its easy to carry and surprisingly quiet.

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.

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.

Very quiet and easy to maintan

[This review was collected as part of a promotion.] I’ve been using the iQ3800 for home backup during storms and weekend RV trips—and it’s been outstanding. It kicks out 3,800 starting watts (3,100 running) on gas or 3,420/2,790 on propane, giving me flexibility when fuel is tight. Despite its power, it stays impressively quiet, so I can run it overnight without bothering the neighbors. Built with a rugged steel frame and protected outlets, it’s held up to bumps and rough handling, and the Eco‑Mode™ engine control delivers smooth, efficient performance under varying loads. I love the electric start (with manual backup) and the Smart CO™ shutoff for safety. Routine upkeep is a breeze thanks to tool‑free access to the oil fill and air filter. For reliable, low-noise power and minimal maintenance whenever and wherever I need it, the Generac iQ3800 has been a fantastic, peace-of-mind investment.
