Generac Gp2200I vs iQ2000 Super Quiet Inverter Generator

Generac Power Systems is based in America and makes some of the best generators and other power equipment.

Since all their products are designed and made in America, you will end up with a high-quality generator regardless of which one you pick.

To illustrate how good the Generac generators are, we will compare the Generac Gp2200i and the Generac iQ2000 generators. These two are known to deliver the best functionality and power for the money.

From the reviews below, you can pick the best one for your applications.

What to Look For

The Generator Type

Under generator type, you will get three common options to choose from. The three include gasoline-powered generators, propane-powered generators, and the dual-fuel generators.

Some might be asking, what about the diesel generators? Well, these are not common when it comes to portable generators. They would be common in cases where you need a large generator to power your home or office block.

The gas generators are the most common to get because of their reliability and ease of getting gas from any gas station. They will also be compact, lightweight, and easy to start.

The gas generators would be commonly used for tailgating, camping, and other applications that need portable power.

If you want to be more environment-friendly, then go for the propane generators. Also, propane does not degrade over time compared to gas, which can start to disintegrate after several months.

The propane generators however do not run best at low temperatures. Also, their fuel systems can be more complicated making it more difficult to fix.

To experience the best of both worlds, you should consider the dual fuel generators. They are known to give you advantages of both types of fuels mentioned above. You would also easily switch from one fuel source to another depending on your needs.

Generator Compliance and Certifications

Whichever type of generator you are buying, the certifications are important. If a generator can be compliant to the set rules on emissions and safety, then you are sure it will be a great generator.

Some of the important certifications you should look for include EPA, CARB, CSA, UL, and OSHA.

When you find that the generator has most or all these certifications, you can go ahead to buy it.

The Power Output

The overall power output will determine which types of electronics you can connect to the generator.

Before you can decide that a generator would be ideal, first look at your electrical load.

List all the electronics that are likely to use the generator at any given time. Sum up all their rated powers to find the right size of the generator.

From the total sum, multiple this figure by 1.25 to oversize the generator. This will help you get the right size even if you decide to add new electronics, the generator will not be overloaded.

You now have to look at the starting and the running watts. Focus more on the running watts as that is the power that will be available when the generator is running.

Engine Type

The engine is the heart of the generator. If the engine ends up being unreliable, then the whole generator will not work great.

Many generators you are likely to come across will have the 4-cycle engine. This is because this type of engine is less bulky and comes with a simple drive system. You would also be able to maintain it easily.

The powerful portable generators will have the V-Twin engine. Such an engine will rotate at high speeds and you should end up with the best power while keeping the engine weight lower.

Ease of Starting

Ease of starting is essential for someone who is looking for a portable generator.

The most common types of starting systems include electric and the recoil systems.

As the name suggests, the electric start system is where the generator comes with a battery that helps with starting the generator. You simply press a button and the generator starts to run.

There is still the classic recoil system. With this system, you have to consider how many times you have to pull the cord to start the generator.

New generator models would be easy to start even with one or two pulls of the recoil cord.

You are also likely to get some models with both electric and recoil start systems. In this case, the recoil system will be used as a backup method.

The Weight

The weight will be an important consideration depending on how nomad you are with your generator.

If you tend to take your generator on road trips, then you need something compact and lightweight.

Look for models that are less than 80lbs if portability is a key feature that you need in a generator.

It would be nice if the generator comes with a handle or wheels to help with moving it to the desired location with ease.

Noise Level

The noise level is mostly measured at 23 feet away from the generator. So, look at the model’s noise output to see if it would be ideal for your application.

If you have to use it at a campsite, then consider a model that does not generate a lot of noise when working. Having a noise level below 70 dBA should be quiet for most people.
