Ratings & Reviews for Generac 5200 Starting / 3900 Running Watt Gas and Propane Dual Fuel Portable Generator

Super Quite

Purchased for emergency outaage. It Was easy to set up and start, good to go. I was very happy to that it is very quite.

Easy operation

Bought 3months ago and impressed with the product.

Great unit and competitive price!

Unit works as intended with no issues. Seems well made

Dead Battery on an Island

Although it was difficult ro get through to the correct people at Generac, we eventually did and after reviewing our case, they acted professionally and quickly. Thank you.

Parts diagram unavailable

I was disappointed that I cannot find a parts diagram available for download or purchase anywhere online. The product is good, but owner support seems lacking in this respect.

Disappointing purchase

Purchased a Generac inverter generator on 4/26/2026. Would not operate from the first try. The generator would not run for more then one minute at a time then stall. It has been at the repair shop since.

Failed after 70 hours of use

Around 70 hours of use it would turn off about 1 hour in during use then start up again after it cooled even when it was in a well ventilate area in the shade. I purchase the 2 yr warranty with Lowes shooes you to, Assurron shooes you to manufacture, currently stuck here trying to move forward.

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!
