Excellent

Bought this generator because I could not find the generator that I was looking for- turned out I got a better generator at a better price! Light weight compared to other generators in its class, very quite and looks great. I recommend this generator to everyone I meet. I’ve demonstrated it several times to other campers as we travel across America.

Great for boat lift

Purchased this for a boat lift for a 23’ runabout and it works great. Impressed with how quiet it is and how easy it starts. I’ve only used it one boating season but just started today after it sat for almost four months to drain the gas. Took about 5 or 6 pills to get it started but once started worked like a charm. I’d definitely recommend.

IQ3500

Out of the box the IQ3500 i bought was leaking gas. Tried tightening the drain valve. Still leaking. Called Customer service and they were worthless. Told me I had to drive to a dealer one and a 1/2 hours away. Then told me they could not say this was under warranty even though was just out of the Box 2 weeks earlier. Decided to take it 15 minutes away to a small engine repair specialist. He found that the major gas line out of the tank was ripped. Cost me 60 bucks to get repaired. The customer service from these guys at Generac is absolutely worthless. I do not recommend Generac products on customer service alone.

Quiet, small footprint, easy starting.

I got the Generac IQ3500 to replace a much cheaper, much larger, very much louder generator. The Generac doesn't have as much power, but is so much better in the size and noise areas. I had never really used our old generator and I gave it to my son who used it to build a shed on his property. It failed after a few hours, It was cheap, but had no reliability. The Generac is so much nicer. It doesn't come with wheels but a $30 simple cart makes it portable. It now takes a much smaller spot in my small garage than the old unreliable generator. I have not really used it yet (other than to test it) since it is meant as a power back-up.

Great product with poor quality control.

Unit arrived in what appeared to be good condition. Followed instructions to the letter to prep and start. Generator never made any attempt to fire/start. After researching Service/repair supplier(lost two weeks of potential use), then took unit to repair shop (another 10 day delay), only to find that the fuel line was installled with a crimp in it, therefore no gas was reaching carburetor thus it would have never started. Repair was under warrantee, thank goodness. So after a month from arrival, I now have it back(yesterday) and hope to get to try out use. Size, features ( outlets(110 and USB, quietness, and form, fit, function) seem very good. Just need time to exercise use/utility. Disappointing start and significant effort for me to handle, transport, and get repaired but hopefully now in a position to get the utility I needed without more unnecessary delay. General, please review your quality control procedures so this does not happen to some other poor, unsuspecting soul!

Generac has great features

Being in my late seventies this unit was recommend by my son in law because it would be lighter and quieter. We do a lot of ice fishing and the dealer also recommends this unit to handle all of our needs. It also has sleek features and handles easily.

Dual fuel generator

[This review was collected as part of a promotion.] With the weather been weird and the power go out quite often at my place. Receiving the generator is a game changer. Even though, it is about 111lb, but the generator come with wheel which it make it easier to carry around. This is a dual fuel, it can run in both either propane or gasoline. Easy to use with electric start, just push the button. It is easy to maintenance and its quieter than the other brand. I would like to recommend it.

Great Product!

Have this on our bowfishing boat pulling 12 100 watt leds. It's super quiet and very reliable. Only flaw I have found is the pull cord has a deep fray in it after one night. Will be going through warranty to get it replaced. Great product and easy maintenance!

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.

IQ2000

Bought this unit for camping so I can charge the trolling motor batteries in my boat. This generator is much quieter than expected and is extremely efficient. It starts with half a pull of the start cord and is basically vibration free. I would defiantly recommend it to anyone who needs a generator that can he carried by one person.
