Ratings & Reviews for Generac GP3500iO 3500-Watt Inverter Generator

New replacement

Replaced a faulty unit that would not run on propane with a new one

Great Features on the iQ3800 Dual Fuel generator

I am very pleased with the iQ3800 Dual Fuel Generator because of all the features it includes. It provides great value as a standby for living in an apartment in an area which is subject to get periodic ice storms and resulting power outages.

Power Outage - Generac 3300i

Within a month of purchase, we had a 30 hour power outage. I ran extension chords through the garage and into the house, and we powered a small space heater and some LED lights. We were very glad to have this generator to support us during this difficult time.

Good generator

Good machine. Not too hard to start , only negative is filling with oil it is hard not to get the oil inside the machine. Glad I purchased it.

Beyond disappointing

I bought this a couple months ago. It never worked. The Fleet Farm I purchased it from would not take this product back. The generator is still at a small machine engine shop. I will never buy your products again.

Bad service

Did not run right. Received as a gift. Repair shops only work on ones they sell. Ordered a new carburetor installed it my self.

Absolute junk!

Bought a new portable generator and it does not run once I put any kind of load on the unit. And there is no service repair shop anywhere close to my home.

After many years I had a slight problem. I contacted Generac by email and explained my situation and received a response with useful info and the schematics I requested. Problem solved, Thanks

Great Features, Nice Package, Nice Price!

Got a decent deal on this product, was looking for a nice inverter generator to serve as a backup option for our small business. My only gripes on this is that you have to take off the side panel to service the oil (would rather there be a way to check and fill oil without a screwdriver) and that the Off/Run/Choke knob was easier to turn and gave some sort of haptics or snap to indicate that you are on proper setting (Run vs. Choke).

Problems

When you purchase a generac you will be less than impressed. They will fight you on every warranty claim, you can’t even find a parts manual online. My generator is hardly 2 years old and have had nothing but issues and absolutely no help from Generac. You will regret it

So far its perfect

I bought the iQ3500 for my off-grid cabin to help charge my battery bank when solar is not an option. I also use it to run a small a/c unit when its hot. I have over 120hrs on it and have never had an issue. Its very quiet and has never given me any issues. For what I need it to do it seems perfect.

RELIABLE

Trip planned boondocking for part of it, all is well until it's not! The Sun didn't shine so no solar load. Backup gen wouldn't pick up load. Generac to the rescue!! The iQ5200 worked flawlessly, and saved us!

Best silent generator ever

Extremely silent for the power! Love mine and never got faulty. Easy start and last long on eco mode.

parts manual

Can’t find a parts manual anywhere. I need to replace the side enclosure panel. Other than that it seems to be working fine. Just need to go camping and try it out

At 105 lbs. HARD for 89 year old to lift out of

Generator is quiet and started on 3rd pullstart. Instruction misleading on electric start! Shows how to hook battery at battery studs! Cost me $20 to find out line behind battery was unplugged! Already hooked to fully charged battery!! Quietly does job using very little gas, haven't tried LP yet. WELL satisfied with it! Used to trim all my hedges about 4 hours, some 150 ft from a plug in! BLESSINGS!!!

decent capability for the price Difficult to maintain the carb if gas left in the unit long term always drain the gas when finished

Great generator for the price!

I recently purchased a Generac 3300i inverter generator for my camper, and I couldn’t be happier with it. It’s quiet, efficient, and easy to start, making it perfect for camping trips. It’s lightweight and portable, so loading it in and out of the camper is no hassle. Overall, an excellent generator for the price—reliable, well-built, and great peace of mind when I’m off the grid.

Worked as advertised. Saved my food supply!

Used it twice now for neighborhood wide power outages. It has enough power to keep a refrigerator, freezer and some electronics going. For the first outage I had charged the battery and it started with the electric start. For the next outage, battery wasn't charged enough. However, the pull start worked easy on the first try.

Great portable Inverter/generator

I'm very pleased with the purchase of this model Generac Inverter. Really like the dual fuel operation and its low noise level. The other features that did NOT disappoint is its mobility to move around with the clever pull up handle, makes it very easy to maneuver as I'm a senior citizen. Also, pleased with having both the electric start and pull start option should the battery get weak/fail. I purchased this to have an emergency backup for electric to our home in case we lose power during stor...
