A Great Generator at a great price

After spending a lot of time researching different generators this is the one we bought. It has a lot of the features that the more expensive ones have and it is very well priced for those options. The best part is hearing or I should say is not hearing it in action. It is very quiet and does the job.

Began positive

I have had several carb issues. I worked where we sold Generac generators, and always spoke highly of them. I owned a GP5500 prior w/ few problems. I always kept ethanol free gas or gas w/ Stabil in my IQ3500 . Which purchased 9/2019. I had one carb replacement a year ago ,after a month wait for parts from Generac. It would start but not run and the ECO setting would shutter and shut the engine off. Now it is repeating problems, after only being run on ethanol gas for less than 1 hour. We used it to run the 13.5K A/C or to run heater fan and charge RV batteries. We were able to do one or the other at a time. It was never able to pull the 25 Amp specs.

Wow. Great price, great brand, good product for the price

I purchased this at a sell price that was a hundred dollars off suggested retail which was a super buy. I had considered a Honda, but for the price, this unit is the bomb! Just a quiet as a Honda and MORE running watts, two 20 amp outlets, two usb charging ports and capable of charging a car battery. The Good: The generator is quiet, easy to set up and start, portable, comes with the battery charging cables, initial oil and worked flawlessly during my one hour initial test. I am very happy with the performance of it. The Bad: fit and finish has a lot to desire. The control panel was bulging at one corner and a screw on the panel was striped out.The spark plug is difficult to access, removing the plug wire is a chore. What could be Better: Filing the oil is also strangely difficult, they provide a funnel but the fill port is at a right angle to the unit and at the bottom. Basically when oil stops going in while filling, it is full (messy). Filling the gas tank is also odd. You have no way of knowing how much gas is in the tank. When filling, the spout of the gas can fills the opening which has a screen inside of it and you cannot gauge how full you have it. I see a big problem when filling a hot generator this way! Side panel is removable with two phillips screws, but hand twist screws would be so much better! This allows access to fill/check the oil, drain the carb for storage, and the air filter. I wish it had a digital read out for watts used but at this price point I understand. Why can't manufacturers engrave the maintenance schedule and oil type/amount, plug type, etc on the generator so it would always be handy?? Would I buy this again? Absolutely! The price, brand and running watts makes this an outstanding deal. I can live with the minor flaws.

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.

Good product

I think its a great generator, however it was damaged upon delivery. The housing cage was bent and the panel also a little bent up. Normally I would have sent it back but needed it ASAP. Overall it runs great but was extremely disappointed with the damage upon delivery.

Brand new out of the box and to the shop!

We ordered this Generac generator because of the positive reviews but sadly are disappointed. We had to order two and neither one of them worked as they should. The first one the exhaust blew white smoke and a strong odor of fuel/oil. We followed the instructions in the owners manual. We ran it several times hoping it would go away. It was suggested by Generac customer service to send it back. We ordered a second one with high hopes that this one would be good. However, after prepping it as recommended in the owners manual, the green ready light did not come on. We plugged lesser expensive equipment in to the unit and it worked. However, if the ready light isn't working properly, how do we know the overload and oil lights are working. This time Generac customer service suggested we take it to a certified place of service. So we have a brand new out of the box Generac generator at a service center, never been used. Very disappointing. It's been 5 weeks since we ordered the first one and we have yet to have a working generator.

Worst Inverter generator ever

A total waste of money. Started generator every 3 months for first year. Let it run. All good. Needed to use it and would not work at all. Could not generate any power. Took it for service (of course out of warranty)come to find out the electronic board that processes that power was shot. received an estimate of $400 to repair my $700 generator that was like new. Generac rep said they had issues, but unfortunately my unit was out of warranty, To Bad. Wont be ever be buying a Generac Inverter Generator. When I get the money, I will be looking at Honda. Total waste of $700+, plus not having a unit when my power went out.

Great Product

I bought this generator because I needed something lighter and easier to handle. Have no problems whatsoever with my generator. The only issue I have is I would love to have a wheel kit for my GP3300i, when I go online the only kit they show on all sites is for the 3500 model.

Ready When We Need It!!

[This review was collected as part of a promotion.] I was lucky enough to receive the Generac Dual Fuel Portable Generator as a gift from Influenster for review, and while we haven’t needed to put it to the test yet (thankfully, no power outages!), I can already tell this is a game-changer for our home. From the moment it arrived, I was impressed. The generator feels incredibly well-built — solid, durable, and thoughtfully designed. The dual fuel capability was one of the first features that caught my attention; being able to choose between gasoline and propane adds so much flexibility and peace of mind, especially during emergencies when fuel availability can be unpredictable. Setting it up was straightforward. The instructions were clear, and the controls are easy to understand, even for someone who isn’t super experienced with generators. I also love that it comes with a mobility kit, making it much easier to move into place if and when we need it. While we haven’t had the chance to run it yet, just knowing we have a reliable, high-powered backup ready to go is a huge comfort. I truly appreciate that Influenster gave us the opportunity to be ready for whatever comes our way. Can’t wait to update this review once we officially put the Generac to work — but for now, it’s getting five stars just for the quality, design, and peace of mind it brings.

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.
