Nice portable unit. Great price!

We were looking for a portable unit for deer camp and ice fishing. After researching other portable generators, went with the IQ2000, believing this will meet our needs. It's nice to see the remaining fuel level and like the different mode options. Nice unit!

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.

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.

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.

good unit, started first pull out of the box!

It would be usefull to have known the derate info before purchase. The info is on page 5 in the book. 3.5% per 1000ft above sea level is significant at 10,000 ft. If I had known to reduce the expected output by 35% I would have considered a larger unit. I'll still put it to good use and the portability is wonderful.

Generly like to power to weight ratio.

I got the generator (Craftsmen 3000i) last spring and used it on two camping trips. It worked flawlessly. However, the last two times I have tried to run the unit it has been very difficult to start. I had to remove the plug and use starter fluid. Yesterday I removed the spark arrestor and discovered it to be quit dirty. I cleaned the spark arrestor and also checked the plug. I installed a hour meter as soon as I got the machine and as of today there are only 38 hours of run time. Even after performing this early maintenance the unit was still hard to start. I really like the weight to power ratio, but am concerned on the starting difficulty.

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.

Excellent product. Better than Honda. More features.

The Generac IQ2000 generator out performs the Honda generator. I love everything about it. After looking on YouTube and the internet I decided to go with the Generac. Price is just right. I am a retired Firefighter and First Responder after 39 years. Used all types of generators in the fire service. Thank you again Generac for a great product. Will use the generator for my personal use during storms, etc.

Price is right

I bought 1 and put the whole package of oil in and I believe that caused it not to start. I took it back and exchanged it for another identical one, this time I didn't use the whole amount of oil provided. The 2nd one works like a champ, first pull start for now. Have not had an opportunity to run for extended times so will have to update this review at a later time. I work construction and have been around many Generac products without any issues and was a driving force in my purchase.
