Great generator

I bought this last night at mills fleet farm due to the outage from windstorms in our area. Utility keeps pushing back power back on time and date. As these outages are becoming more common, I purchased this for these emergencies. Started first pull after removing from box and adding fuel and oil. Unit is fairly quiet. Ran my freezers and refrigerators, tv overnight. Was surprised, unit ran longer than anticipated at about 8.5 hrs. Very pleased. So much so, that next bring I will be installing a complete home stand by gen set with auto switching. So tired of our outsourced utilities. Generac hit a homer as far as I’m concerned. Great product.

Very Quiet As Advertised

I purchased this for the same reason as many others. I wanted a reliable power supply for my travel trailer. I also wanted something quiet so others wouldn't be annoyed at camping areas. Set up was simple. Connect the battery, put in the oil and gas and it is ready to go. Started right up and ran smooth and quiet. However, while running, I heard a slight vibration noise that didn't sound normal. After a little investigation I saw that one of the standing frame supports was cracked where it mounts to the base of the unit. (Access door side on the left) I'm certain this is not a manufacturing flaw, rather something that happened during the shipping process. I called the Generac customer support number (On a Saturday during a holiday weekend) and spoke with a very nice woman named Linda. She registered my product and informed me that this is something that would be covered under the warranty. She was able to get me in contact with a local authorized repair shop. I have since contacted them and they have the replacement part on order. Service after the sale is extremely important. I was pleasantly surprised how smooth this process has been to get the repair done.

This dual fuel generator is a must for every home.

[This review was collected as part of a promotion.] My power goes out way too often due to trees breaking during storms. I have lost so much food as a result, so this generator will be a game changer. At over 115 pounds, it is heavy, but the compact size and wheels make transport easier. With four different power outlets, it means I can plug in appliances, cell phones and lights during an outage. Running on two types of fuel (gas and propane) gives me flexibility for usage. I like the LED display to see the output and gas consumption. Generac is a brand I can trust because they have a great reputation.

Great Inverter/generator

Well it took a week or two after getting my new Generac IQ2000 before I could mess with it. I put the oil in and gassed it up, set evertything to "ON". It took several pulls for it to start the first time but it ran great. I love the "Time Remaining" the gas and also love the load graph, really neat features. It is much quieter that I expected. I think it will be perfect for what I bought it for. Thanks Generac!

Super quiet and gives the needed power

I haven't had a chance to use my new generator a lot yet. However, the little that I have used it, it is very quiet and has the power to run the lights and tools that I. Need. I love all of the extra features that it has to offer for competitor brands. I would recommend to others.

Iq3500

At this point I have not used IQ3500 for it intended purpose. Therefore I am unable to fully rate the product at this point However I do have one concern. The lack of servicing dealers and the availability of maintenance kits in my area More to come

This review is for a GP3300i

I haven’t used it very much, just a couple times at home. We bought it for camping with our travel trailer. It is very quiet and responds quickly under load. So far so good. When camping season starts in Michigan we will be using it a lot more. I think it will work great for our application.

Not worth the price

Bought this last year and was disappointed it wouldn’t run a small ac. It will start up and run for a few seconds but then goes into limp mode. Won’t run a toaster or microwave without going into limp mode. My old Honda 2500 ran it fine. It hardly idles with no load. Tried to return but couldn’t. Told to call generac which I did several times with just the runaround. I basically use it to charge the trailer battery. Haven’t found anyone who can make it work as advertised

Powers on!

[This review was collected as part of a promotion.] This generator is a a solid choice if you’re someone who loves to go camping or even a good choice for a job site if you need back up power. It’s actually pretty quiet for a generator and I think it’s great that it can also be hooked up to propane.

Unbelievably simple to use!

We live in SW Florida and decided to buy a generator for future power outages. Have not had to use it until today. Power went out 1.5 hours ago. This is the first time we have used it. Dumped some gas in and it fired on the first pull. That never happens to me! 10 minutes after the power went out I had the fridge, some lights, a fan and some other minor things plugged in with room to spare. So simple and I am far from a handy guy. Highest marks from me
