Generac iQ2000 Review

Power & Output

When it comes to all of the different models and designs of generators, it is the power and output of the device that is key to everything. 

The power and output of a generator is measured in Watts. Getting your head around the levels of Watts a generator has won’t only give you a better understanding of the generator’s power but can also ensure you have an idea of what it can run. 

The Generac 6866 iQ2000 has a top power level of 2000 Watts and a general running level of around 1600 Watts. 

The device can be rolled back down to the 500 Watt mark with relevant ease, giving you far more control over the power of the device.

One of the most unique features of the Generac 6866, iQ2000 model, is the triple mode output. 

This allows you as a user to set a particular power level, depending on how you are going to be using the generator. 

The economy, turbo, and standard power settings all give users a simple way of changing the power and output settings. 

This not only allows you to use fuel far more efficiently but also stops you from overloading devices with too much power.

An incorporated power inverter can also increase the amount of power from the generator and improve the capabilities of the device when linked with another generator.   

What Can Generac iQ2000 Generator Run? 

With around 2000 Watts to play with, the Generac iQ2000 Generator is more than capable of providing you with enough power for most requirements.

Although you may have to opt for a far more powerful device if you are wanting to power the entire household during a blackout or natural disaster, the Generac iQ2000 is a winner when it comes to power.

If you are looking for a generator that is capable of running household items such as the refrigerator, freezer, or any lighting systems, then this generator is more than up for the task.

The runtime of the Generac iQ2000 is just under 8 hours of runtime at a quarter load, meaning it is more than capable of maintaining its output for a long period of time.

When it comes to overall power capabilities and output levels, the Generac iQ2000 is the ideal camping or RVing generator. 

Running lights, camping fridges, and all manner of RV equipment come easy with this model of generator. 

Fuel Efficiency

The fuel efficiency of this device is something that is seen throughout all the Generac iQ2000 reviews and is definitely something to shout about. 

With a fuel capacity of just over a gallon, the generator starts out with a humble amount of fuel yet can make it last for quite a long while.

Getting an easy nine hours out of this one gallon can be achieved with relatively little effort, and with the handy and easy to use runtime display, you are always in the know of how much time you have left. 

The Generac iQ2000 generator is equipped with an 80cc, four-cycle engine. 

Although this is much smaller than many of its competitors, it also comes with a more advanced alternator, allowing it to perform at a higher level overall.

Portability, Size & Weight

One of the Generac iQ2000 shining positives is its portability and mobility. 

Weighing in at only 46lbs, the maneuverability of the generator is something that most customers and users can settle into with ease.

The super-compact design of the generator means that it can not only be carried and transported with comparative ease, but it can also be stored in a variety of different places whether this is in the trunk of your car, the back of the closet, or securely in a garage box.

The portability and small dimensions of the generator also make it a fantastic device for camping, RVing, or moving around a farm or building site. 

Unlike many other generators of this size, the small stature and weight doesn’t take anything away from the usability of the device. 

The user interface is one of the most simple on the market and can be navigated by even the most inexperienced generator user.   

Control Panel

Another feature that is constantly championed throughout Generac 2000 reviews is the uniqueness and usability of the control panel.

Much like the dashboard of a car, the multiple LED displays at the top of the generator showed both the fuel gauge levels and the output levels. 

Also located at the top of the generator’s control panels is the unique run time display – an ideal control panel that tells users how long there is left. 

The lower half of the Generac iQ2000’s control panel is turned over to controlling the different modes of the generator and the circuit breaker. 

Using the three different mode settings gives you far more control over how you use the generator. 

You are also able to get much more out of the generator by using the three mode setting. 

Simply by checking the power bar, you are able to adjust the setting and save on fuel consumption and avoid overuse. 

This unique and easy to use control panel is one of the features that sets this generator apart from others. 

The easy to navigate control panel allows a range of users to use the generator with complete ease.    


The warranty that comes with the Generac iQ2000 generator covers the customer for three years. 

This three-year warranty covers both the generator as a whole and the engine inside.

A three-year warranty is something that is rarely seen with generators and covers a whole host of different problems. 

Backed by a strong customer service base, Generac is also well-known for providing helpful and constructive warranties and services.

As the company is based in the US, American customers will find that dealing with the warranty, repairs, and replacements is all extremely easy and straightforward.

It should be noted, however, that attempting to repair or replace anything on the generator yourself may result in voiding the warranty. 

It is therefore important to contact the warranty provider before attempting any repairs or replacements.  

Noise Level

At one point in this generator’s history, it was the quietest generator on the market – rarely can we make such a guarantee of low noise level as this. 

Although there have now been far more advancements in generators’ noise levels, the Generac iQ2000 still has such low noise levels that it is one the best you can buy.

Measuring it at only 53 dBa, the noise level on this generator is the equivalent of a low-level conversation. 

With such little sound produced by this device, it instantly makes for the perfect camping generator.

Marketed as the ultra-quiet generator it is, many customers of the Generac iQ2000 opt for this model for that very reason.  

Generac iQ2000 Generator Customer Reviews

When it comes to Generac 2000 watt generator reviews, there are generally far more positive points to be taken than negative ones. 

Across the board is generally accepted as a great generator for a few reasons.

The one major point that has been made over and over is the compact portability of the Generac iQ2000. 

Although it may never be your go-to generator for providing a huge amount of power, what it lacks in overall output, it sure does make up for in maneuverability.

Alongside the portability of the device, another feature that was reviewed extremely favorably is the generator’s low noise level. 

This is seen as the generator’s best feature among many of the reviewers.

When it comes to negative points in the customer reviews, there are a handful of points that are highly contested. 

The first is the lack of USB and DC ports on the generator, something that may frustrate the modern user.

The second is the smaller and less noted point of the generator’s poor performance at a higher altitude. 

Finally, reviewers have noted the price tag is a little steep for the features you receive with the Generac iQ200.    

Our Verdict

Concluding our review of the Generac iQ2000, there is a lot to be said about this generator’s capabilities. 

Admittedly, if you are searching for the wonder generator that has the output to power an entire household, this is not the tool for you.

However, if you are looking for an extremely well-designed power supply that can be taken anywhere and used by anyone, this is the generator you need.

Packing a punch of electrical power within such a lightweight and mobile piece of kit means you have a streamlined and easy to use generator that can provide sufficient power.

With a three year warranty for both the engine and generator, you know you’re in great hands if anything should go wrong.

Although you may have to expand your budget a little, the extra dollars you do end up spending are worth it when it comes to the Generac iQ2000.
