Differences Generac GP2200i vs GP3000i explained

People who are more experienced with generators could be able to choose between the Generac GP2200i and GP3000i with the tables above.

That being said, you could also benefit from a bit more information about certain differences.

Running and starting watts

How much power a generator offers is one of the most important details when making a decision.

This area has two subcategories called running and starting watts.

Starting watts is the initial burst of energy a generator offers to get certain appliances and tools going.

After that, you still need enough running watts to keep your electrical devices going.

The Generac GP2200i “only” comes with 2200 starting watts and 1700 running watts.

A 2200-watt generator can run a few devices that tend to be small to medium-sized.

If you plan to run stronger tools or just many medium/smaller ones, you will likely need the 3000 starting watts and 2800 running watts of the Generac GP3000i (or something stronger).

Winner: Generac GP3000i

Outlets

Even if the Generac GP2200i is strong enough for your needs, having the right outlets available makes your life a lot easier.

In certain cases, the outlets of the Generac GP3000i could even be necessary.

Before going into the details about why these things are the case, the Generac GP2200i comes with a duplex of 120V 20A 5-20R outlets, a round 12V DC outlet, and a USB port.

On the other hand, the Generac GP3000i has a 120V 30A L5-30R twist lock, a duplex of 120V 20A 5-20R outlets, and two USB ports.

While the 12V DC outlet has its uses, the main difference to keep in mind is the 120V 30A L5-30R twist lock.

This outlet is relevant because there are certain devices that need 30 amps to run.

Additionally, the twist lock design can be helpful if you have any devices you really want to keep connected to your generator.

In short, the outlets of the Generac GP3000i can be useful for certain devices and situations.

Winner: Generac GP3000i if you need/want a 120V 30A L5-30R twist lock

Winner: Generac GP2200i if you need/want a round 12V DC outlet

Price

Most people will prefer the Generac GP3000i over the Generac GP2200i in terms of dry features.

However, you likely still care about the price differences between these generators to at least some extent.

While this can vary over time, the Generac GP2200i is currently a good amount more budget-friendly than the Generac GP3000i.

Some margin of safety in terms of power potential can be useful but at the same time, choosing the Generac GP2200i can save you some money if it is good enough.

Winner: Generac GP2200i

User reviews Generac GP2200i vs GP3000i

Do you need the Generac GP2200i or GP3000i?

In short, the Generac GP3000i has more power potential and an extra 120V 30A L5-30R twist lock outlet.

On the other side, the Generac GP2200i has a longer run time, outlet covers, a lighter weight, and a price that is a good amount more budget-friendly.

The main questions when choosing between these Generac generators are how many watts and amps and what outlets you need.
