Very quiet and portable

Would Recommend

Runs everything I need it to- AC in the RV, Power tools when off grid and it’s light enough for this old geezer to pack around. Also so quiet that I can hardly hear it running from 35 feet away. Will be handy to run the freezer or whatever if the power goes out .

Dead battery

Would Not Recommend

Bought it in February. Unpacked it in October. Battery was connected (wasn't supposed to be) and there was oil in the motor (wasn't supposed to be any oil). Must have been a refurbed item. Battery is dead and is not covered by warranty.

Works very well and is QUIET.

Would Recommend

Our power was out for four days and my generator failed. I purchased the GP2500i and filled it with oil and gas. It started on the first pull of the cord. I ran it for the next day and a half to power the refrigerator, TV and some lights. It ran for at least 8 hours on a fill up. I never let it run out of gas but I know it was more efficint than my previous generators.

Was great in a pinch

Would Recommend

Fantastic unit. I would recommend to anyone. My only complaint and not even enough to give less stars but the unit is heavy and would be nice if it had some low profile wheels for easier moving.

Never worked under load

Would Not Recommend

My neighbor brought this new and it never worked since new. She gave it to my and I contacted warranty department and the said to take it to a city repair shop. The shop could not get help from the company. Thankfully I didn’t get a whole house generator. I have paperwork to show lack of help from manufacturer.

Lasted 10 hours

Would Not Recommend

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....

Out-of-the-box failure

Would Not Recommend

3300 I set up easily and started on the first pull. I didn’t actually put an electrical load on it for a couple of weeks, and then discovered it wouldn’t run anything. I used an electric meter and discovered it was putting out 90 V. The store I purchased it from has a policy no returns once you put gas in a product. Generac warranty phone support give me the name of the place to take it. It was over 200 miles away, and I live in Metro Central Iowa. After doing further research it looks like thi...

good unit, started first pull out of the box!

Would Recommend

It would be usefull to have known the derate info before purchase. The info is on page 5 in the book. 3.5% per 1000ft above sea level is significant at 10,000 ft. If I had known to reduce the expected output by 35% I would have considered a larger unit. I'll still put it to good use and the portability is wonderful.

Good quality and value.

Would Recommend

I choose it for my Rv. I took it on an12,000 mile Alaskan trip which included frost heave and dirt roads. The only issue is it quit cranking off the electric start. It does crank easy off the pull start. I had to use the pull start most of the trip. It was new when I left. It’s super quiet! If others are running around I couldn’t hear mine at all even though theirs were a good distance away. Generac meads to sell it with a cover or sell a fitted cover. I had a problem with dust getting in the r...

Overloads for no reason.

Would Not Recommend

I bought this unit for a month long trip. This thing turns off after a very short time displaying"overloaded" no matter what you do. I tested it with just a 1500 watt coffee pot and same result... "overloaded" Very dissatisfied with this product as it left us without power for a majority of our trip which was 80% dry camping. Don't recommend

Great looking , quiet and affordable generator!

Would Recommend

Researched inverter generators on YouTube for hours to find the perfect unit to power my camper at unserved sites. Narrowed my choice down to the Honda EU 3000is or the Generac iQ 3500, but it was the Generac’s cost that made it the easy decision! For being equally (or possibly even more) quiet, 20lbs lighter and having nicer features such as a keyless starting switch, automatic choke, and a display screen for monitoring voltage output and run time to gauge oil changes it knocked it out of th...

Great Quiet Invertor

Would Recommend

Runs my 30amp camper flawlessly. Camped beside people running a predator 3500 and a Westinghouse 4500 and this IQ3500 was much more quiet and lasted longer between fill ups. I can’t even hear this running when in the camper and eco mode turned off! A+ buy all around!

This product let me down

Would Not Recommend

I purchased your iq3500 in August of 2022 and used it to power my RV twice in less than a year . The Electric start quite working in June is 2023 (less than one year ) , I checked the battery it was good . Would not do anything, I assume the starter went bad . Then I pull started it , started fine first 2 times . The third time that I tried to pull start it the pull start rope broke . The unit is less than a year old and has only been pull started 3 times and the rope broke and starter quite wor...

Iq3500

Would Not Recommend

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

Quiet

Would Recommend

I have owned a Generac pressure washer for more than 20 years, and previously owned a whole house generator, I have/had great service from both. Decided to purchase a small stand by generator - GP3300i. I have ran for a few hours and very happy. Quieter than I expected and does what I need.

Great Generator

Would Recommend

Bought this generator to power my RV for off grid camping. Have only been out with it once so far but are very impressed with it. Starts like a dream and easily powers my AC and other things. Runs very quiet on economy mode. My only suggestion is that it needs wheels since it’s quite heavy to lift.
