Soooo quiet!

[This review was collected as part of a promotion.] The iQ3800DF generator by Generac exceeded my expectations by a mile! Out of the box, it come practically assembled. All you have to do is add the supplied oil and gas and it is ready to start up. The dual functionality of gas and propane is one of many excellent features. It has a pull start as well as an electric push start button thanks to the supplied internal battery. My favorite part of this generator is the low sound levels. I could not believe how quite this unit is! If you activate to "ECO" mode, it lowers sound levels another (in my estimation) another 25-30%. Maintenance seems to be easy! There is an easily accessible oil drain to make oil changes a breeze. Overall, this a fantastic generator and I highly recommend a Generac to anyone looking for a quality portable genrator!

Great looking , quiet and affordable generator!

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 the park!! Generac…please make a nice fitted storage cover for this generator! It is a beautiful unit and deserves one! Only one complaint is that the generator started surging right out of the box brand new. I carefully added the included engine oil to the correct level and poured in clean, fresh gas but it needed a carburetor cleaning probably from having residual gas sitting in the carburetor or float bowl during product testing before packaging and sitting in a warehouse for 2 years until I purchased it. Service was covered under warranty, it was just the inconvenience of having to take a brand new unit in and the frustration of fiddling with it myself for 4 hours previous to the service. (I removed and cleaned the carburetor personally, the service centre only removed the float bowl as people are lazy now). ***Be mechanically inclined if you buy this generator. Good service doesnt’ exist anymore. No one will help you. 😑***

IQ3500

I usually never purchase a new product for which I can not find other reviews. I purchased this generator for the portability and the compact size. I am 100% glad I bought this model. Started the first time, ran quieter than I expected. I am considering on purchasing a 2nd unit and hook them up parallel with each other.

Realibility

I bought this generator because of its realizability. We lived in NJ, during both hurricane Irene in 2011and hurricane Sandy in 2012. In both storms we relied on a Generac generator for solid performance for over two weeks without electric. This was huge, as we owned a dog kennel in which we were able to keep going, helping a lot of our customers care for their pets. Tom

Can work on both gas and propane

[This review was collected as part of a promotion.] I’ve never had or used a generator before so was super excited to get this; always wanted one. As you can see from our video it’s super easy to use! Just be sure to connect the battery, add oil then either use gas or propane and you’re good to go.

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.

Good build quality, and Quiet.

So this is my first time owning a decent sized generator, and I didn't want to skimp on quality. this generator has surpassed my expectations, it is very quiet (on my last camping trip I even had a few people ask me if it was running when it was). I have only used it twice so far since I bought it so I can't say much about the reliability but I know that Generac makes some good products, so it should last me a long time. It does have some good features, what I like the most is it has a digital readout for the fuel level so your not guessing. Overall a good product for what I need it for so far.

Don't be 'one of those guys' while camping

I bought this to use with our 26 ft. camper. Sites with hook-ups are becoming more difficult to get with the increase in post-pandemic campers. I wanted to have full use of my camper but didn't want to listen to (or have my neighbors listen to) a loud, open-frame generator. This generator is SO quiet. It is barely louder than ambient noise at the campground when sitting in our site, and is virtually in-audible by the time you are 50 ft away. Set up was super easy. Connect battery cables. Add oil and good gas (91 octane with zero ethanol is BEST.). Turn on and push start... It is very well built. None of the problems noted in other reviews. My only 'complaints' is the weight and the oil drain design. 100+ pounds seems heavy for a unit this size. But I knew the weight prior to buying it. The oil drain design could use some work. A 4" hose that would slip out through the bottom oil drain port would be a HUGE improvement.

Lasted 3 years

I estimate I got a little over 1200 hours of use before the 120V port to the inverter fried rendering the otherwise perfectly running and maintained generator useless and shortened my already expensive camping trip. When I explained the issue to customer service, I was told I needed the control panel so I ordered it. While waiting a month for that part ($150) ordered an identical unit as my backup thinking running in parallel could be handy at some point. The control panel came and I found out it wasn't the part I needed. I looked for the inverter part and was amazed that the replacement inverter costs more than the whole unit cost me to replace. Hindsight being 20/20, I would have replaced it with something else.

Great for Tailgating

GP2200! is perfect for a tailgate with all the bells and whistles that make a great tailgate. Ran a TV, Laptop, Electric food warmers, Fans and more with no Problem. One pull start up, super quiet didn't even notice it. Looking forward to exploring other Generac products for my new lake house.
