Review: Generac IQ2000 Portable Generator – Pros & Cons

What is the worst thing about generators? They're noisy!

Especially when operating at max load, most of the generators on the market make a significant amount of noise. Generac saw an opportunity and decided to make a super quiet portable generator.

The Generac iQ2000 is indeed quite quiet but it also features a number of additional attractive qualities.

Functions and Ease of Use

The iQ2000 is simple to use. You power it up with a heavy duty pull cord. A simple power dial lets you start, run, and stop the generator.

A button lets you choose from the Economy, Standard, and Turbo modes.

  • The Economy mode is great for smaller loads and it's nice because it takes less gas and it results in much quieter operation.
  • Turbo mode is the noisiest option but it lets you operate with full power.
  • For the rest, there is the middle ground Standard mode operation.

A really nice aspect of this generator is that it provides the user with a lot of helpful information.

On the front, there are several displays that present information in a large and easy to understand format.

There is a fuel meter to help you keep an eye on how much gas you have left in the tank.

A wattage meter shows you what percentage of load you’re currently operating.

Another meter shows the total estimated runtime based on the current load. 

All of this data is on the front and it tells you everything you need to know.

A panel of easy to understand status lights alerts you when the generator is running low on fuel or oil or if it’s on the verge of overheating or overloading.

Noise Level - Just How Silent is it?

At one point, this was the quietest generator on the market.

There are currently a few quieter options, but the Generac IQ2000 still holds up as one of the quietest portable generators out there.

With a 25% load, the noise rating from about 20 feet away is 53 dB.

For comparison, 50 dB is the noise rating for “Quiet suburb, conversation at home” according to IAC Acoustics.

In other words, this generator has an extremely quiet operation.

The noise level will go up when operating at a higher load or if using the Turbo mode.

The quietest operation will occur in the Economy mode and when running a lighter load.

Gas Consumption & Capacity

  • Rated Amps: 13.3 Amps @ 120 Volts
  • AC Maximum Output Starting Watts: 2000W
  • AC Rated Output Running Watts: 1600W
  • Rated AC Voltage: 120 VAC
  • Frequency: 60 Hz

The iQ2000 portable generator has a fuel capacity of 1.06 Gallons.

With a 500W load, it will run for approximately 9 Hours.

As mentioned previously, a great feature on this generator is the runtime display.

As you adjust the load, you’ll be able to see instantly how much time you have left.

With the parallel kit for Iq2000 portable inverter, the generator becomes parallel-ready to help you multiply your power and your runtime.

With two units and a parallel kit to connect them, you’d be able to power more devices at once or just be able to have a longer runtime with your typical load.

Service, Manual & Warranty

Generac is a US-based company and they have a good reputation for solid customer service, so in the event of any issues, they are likely to be helpful and responsive.

Although they do have an 800-number (1-866-749-6699) , they seem to respond more quickly to email. 

Whether used for residential or commercial use, the Generac iQ2000 Inverter is backed up with a solid warranty. Both the machine and the engine feature a 3-year warranty

This generator is extremely user-friendly and quite intuitive to use, but it does include a comprehensive manual that is clear and easy to read.

The manual includes instructions for maintenance and gives you suggestions to troubleshoot a number of potential problems.

Looking through the manual online before purchasing is a good idea, as it explains in detail how to use it and how to take care of it.

Generac iQ2000 Portable Generator VS the Competition

The iQ2000 holds its own in a field of several good portable generators.

What makes it stand out are the quiet operation and the helpful feedback displays. This makes it one of the more user-friendly models on the market.

IQ2000 VS Honda EU2000i

The bestselling Honda EU2000i has about the same weight and runtime but it’s just a bit louder.

It also lacks the user-friendly information display.

In a head to head comparison, the iQ2000 has more going for it. Nonetheless, the Honda has a better reputation overall and higher ratings.

VS Yamaha EF2000iSv2

Another competitor, the Yamaha EF2000iSv2, beats the Generac for being just a tiny bit quieter.

It’s not a huge difference but it is there. In addition to being quieter, the Yamaha is also just a bit smaller and lighter than the Generac.

They have matching power ratings, but the Generac does feature a longer runtime.

In a head to head comparison, the Yamaha edges out the Generac since it is just a hair quieter and it also features a really compact and lightweight size.

Reviewing the Generac IQ2000, Honda, and Yamaha generators I found that they are all excellent portable inverter generators.

They’re very similar in most ways, but each model has something to offer that makes it stand out just a bit.

For Generac, it’s that it’s quiet (though not the very quietest) and it is user-friendly and features a very helpful display of important data on the front panel.

Online Reviews and Scores

Compared to both the Honda EU2000i and the Yamaha EF2000iSv2, the Generac iQ2000 doesn’t fare quite as well in customer reviews.

That said, it does do quite well. On Amazon, at the time of publishing this review.

Over 50% of reviews are a perfect 5-stars and those happy with the generator praise it for being quiet, compact, and easy to use.

Several of the unhappy reviewers reported that it eventually stopped working or could no longer handle much of a load.

On YouTube, Doug Bigley reported his initial reaction to the generator was very positive, checkout his video below:

One commenter on Doug’s video review of the iq2000 pointed out that the generator is made in the USA, a nice bonus.

Another mentioned that it has a great heavy duty pull cord, a better one than some of the other models.

Potential Problems / Known Issues

Several people report having trouble with the generator when at higher altitudes.

This is known issue that affects all generators, not just the Generac iQ2000.

Some generators are able to adjust for altitude, but the Generac doesn’t do a very good job at this.

Another issue that a lot of people seem to have with the iQ2000 is fuel leaking. Often, it might just be that the carburetor drain isn’t closed.

This and other potential issues are covered in the user manual.

With the suggested regular maintenance, this generator should function well for years. You should check the oil after every use, clean or replace the air filter every 50 hours, and do several more involved tasks after 100-200 hours or every season.

It doesn’t hurt to think of your generator like you think of a car. You have to put in some effort to take care of it.

When you don’t, frustrating things can happen. When you do give it the regular care it deserves, it will keep powering your devices without problems.

Summary: Should you Buy it?

What’s the most important thing you’re looking for in a generator?

If the noise factor is high on your list, this is one of the very quietest generators. Is it really important to you that your generator be easy to use? 

The Generac iQ2000 6866 stands out with its simple controls and extremely helpful and easy to understand feedback displays.

If you want the generator with the absolute most power, this isn’t the best choice for you.

This is a pretty middle of the line tool in terms of power and runtime and weight and size.

It’s the quietness and the user-friendliness that make this generator special. If that appeals to you, the Generac iQ2000 is definitely worth your money.

  1. iq2000 specs rate 13.3a rated load. in fact, unit will not carry more than 9-10amps continuous without shutting down. After less than 8 months use, inverter ($600 replacement part) failed and not covered by warranty. Three year warranty that does not cover electrical parts is useless, USA made or not.
