Get what you pay for

Definitely not the cheapest, but it'll be worth the money in the long run. All features are as advertised, quiet, powerful, LCD screen provides very useful information. Parallel kit to use two at once works perfect as well. Would recommend to anyone. However, NO WHEELS. Being an inverter generator, this is heavy. So I was surprised when I could not find a wheel attachment for this. It would make moving around so much easier.

A Perfect 10

I unboxed it. Read the owners manual. Popped the side panel off to add oil and gazed at the impressive workmanship of this unit. Put provided oil into it. Put gas into it. Turned the switch to start. Pulled the started cord and was rewarded by the sweet sound of a perfectly tuned 4-stroke gas engine on the first pull. I tested output by plugging in the nearest electrical device which was my shop vac. It fired right up. I'm impressed. Now waiting for Dorian to get here. Bring it! I'm ready.

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.

Great Generator

Bought this generator to power my RV for off grid camping. Have only been out with it once so far but are very impressed with it. Starts like a dream and easily powers my AC and other things. Runs very quiet on economy mode. My only suggestion is that it needs wheels since it’s quite heavy to lift.

Louder than expected

Heat shield over the muffler rubs against the muffler and is loud and annoying. I'll probably take it off and see if I can bend it away so the metals don't touch each other. I bought the generator to camp with so I want to make it a little more quiet. Haven't gone yet. Just filled the oil and put gas in it to test. Ran a heater and skill saw with no issues.

Dual fuel awesome

[This review was collected as part of a promotion.] I’ve been using the Generac iQ3800 Dual Fuel Portable Generator for a while now, and I’m really impressed with how easy it is to operate. The push-button start works flawlessly, and the design makes it super portable with the built-in handle and wheels. It’s definitely built to last—feels very durable and reliable. I also appreciate the Economy Mode to help save fuel, and the LED display makes it simple to monitor everything. Great generator for both work and outdoor use!

Lasted 10 hours

Was thrilled to get this unit and did a ton of research before purchasing. I ran this unit for approximately 10 hours and the digital screen stopped working. This was under a minimal load and under normal weather. After I shut it down for the day there was fuel leaking out of the case and onto the ground. I haven't been able to identify the leak but I suspect its likely carburetor related. I am currently working on locating a service repair dealer which is much harder than I thought it would be. The only dealer I have found listed on the Generac website who actually does repairs is 16 weeks out. I might have got a lemon of a unit but regardless its frustrating that there is no great repair options.

Great product so far.

Like this product because the noise level is very low compares to others. Love the display gauges that display gas level and remaining time. All portable generators should have this. Using this unit as a home backup to keep the fridge running and some lights during blackouts. So far so good.

Work horse

I had my eye on the other name brands and happen to find this one on sale and bought it on a whim. Couldn’t be happier, it has powered my appliances during a hurricane outage. I’ve used it for power tools around the farm for repairs and maintenance. Mostly I use it to power my boat lift, which lost its underground service earlier this year. I used it several times a week to run the 2800lb 1/2hp boat lift up and down. I did the calculations and it should not have enough power to start the motor, but it manages. It definitely has its limitations, keep in mind this is good for one large appliance, or a few small ones. I have definitely tripped the breaker and choked it off, but give it a second to rest and crank it up again. Also, this generator is quiet, I can easily have it running and talk on the phone right beside it. One more thing, I taught my six year old son to start it, easy.

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.
