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

Good but poor enclosure

This little generator is awesome, very quiet Powers more than I expected it to. The major downside is the fit and finish. The front of the enclosure is broken I contacted generac to purchase a new enclosure or parts they referred me to the retailer the retailer referred me to generac. So I've gotten nowhere I've sent emails and pictures. Besides the cracks and the enclosures the generators awesome. Generac contact me hook me up please.

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.

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.

Excellent portable generator

After months of extensive research, I chose the Generac IQ3500 as a home back power source. All of the pre-work paid off. This unit is very well built, runs extremely well, and is unbelievably quiet. Could not be more pleased with this generator. Well done Generac.

very good generator once it was repaired

I ordered the generator on line. After receiving the generator, I followed the directions of setting up and preparing the generator for use. The unit started but did not produce any electricity. I called for Generac for assistance and was offered either return or bring it to a service store. The was the best option for me. After a 5 minute investigation by the service person it was determined that a plug next to the battery was unplugged during shipping. Once this plug was connected to the display screen, the unit worked and is working well after 65 months of starting and running on a monthly basis. Generac, it have viewed several reviews of this generator on line and it appears this is a common problem. Please correct this issue.

Powerful and quiet

I bought the GP3000i for my camper and I am impressed that I could run everything even the 8000 watt a/c without any problem. It’s fairly lightweight and fits right under the camper to keep it out of the direct sun or rain very happy with this product, oh and easy starting also!!

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.

GENERAC 3500 IO

I purchased the 3500 IO back in 2020 in Texas. To date I have 7558.7 hours on the unit, it went through the Big Freeze in Texas, kept my neighbors homes heated during power outages. This unit has had the oil changed every 250 hrs (30W), Lucas upper cylinder gas additive occasionally, a new pull cord at 5800 hrs and a yearly plug change. I recommend this unit for all your uses up to 25 amps, it hasn't let me down. Great unit

More quiet than i imagined

Nice size, unbelievably quiet. I have a Genrac Home Standby generator and have had great luck with it so hoping for the same with the portable. I wish 'RV Ready' meant it had a 30A RV plug instead of 30LR5 Twistlock or at least make it an option to eliminate the need for an adapter. Wish there was a wheel kit, cover, & other accessories available for this unit.
