Easy power during storms

We live in a 1950’s suburb in Sacramento, CA - the City of Trees. We love our trees. But windy winter storms, trees and power lines don’t always work together. After annual power loss for up to 3 days each winter, we bought this inverter generator this winter - a day before the storm. Long story short this unit fired up with ease and powered our fridge, heat fan unit (gas powered furnace), several lamps and even our wifi. The generator ran for 30 hours straight and was an after thought until the power was restored. We’re huge fans now and wish we’d bought this years ago.

I've had the iq3500 for 3 months

... and it cranks good and runs quiet , -- until I plug in something in. Then it makes a whistling or whining noise that is louder than the motor. Called all repair people in my area to check it out and all that are still in business say they only work on whole home generators. 2 of them kindly looked at it and listened and said it may be supposed to make that noise. It charges fine an for now I'll try to enjoy the whistling.

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.

Quiet

I have owned a Generac pressure washer for more than 20 years, and previously owned a whole house generator, I have/had great service from both. Decided to purchase a small stand by generator - GP3300i. I have ran for a few hours and very happy. Quieter than I expected and does what I need.

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.

Made life without power during the huricane considerably more tolerable.

This generator was a blessing. We went from oil lanterns and flashlights to lamps, fans,and TV. We were also able to cook a hot meal with our electric fry pan and pot. The general 2000 started with first pull and was quiet enough for our 3 year old grandson to sleep comfortably. This was a wise investment for a premium quality generator.

Took a while to get it from Amazon but happy with the purchase

Have a 6500 watt Generac that we use for the house when we loose power. Have had for 10 years +. Never any issues. So we thought we’d try an inverter for camping and hunting trips. Very happy so far. Easy to use quiet and runs everything we need it to.

Camping trips here we come !!

[This review was collected as part of a promotion.] Just got the Generac iQ3800DF Inverter Generator and I’m seriously impressed already. Dual fuel (gasoline + propane), super quiet, and easy to move around—exactly what I was looking for. The digital display is a nice bonus too. I can’t wait to put it to the test during our next camping trip or power outage! So far, 5/5!

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.

Very pleased

Purchased through Amazon, arrived in a timely manner in perfect condition. Unpacked, added oil and ethanol-free gas, it started on the 2nd pull. Very satisfied with how quiet it is, will be using it with a small travel trailer. Let it run for 20 minutes with a light load, then shut down. A few hours later it started first pull and I connected to the trailer and started the A/C. The generator was only about 2 feet from the trailer and I couldn't hear it inside with the A/C running. Let it run for 30 minutes, then shut it down. So far, so good. Had to buy the adapter plug, no big deal.
