Design and Construction

The Generac gp3000i generator is one simple to use inverter generator. It includes several convenient, RV-ready outlets in one area and simple to use dial for easy operation.

The machine itself is compact. The lightweight, built-in handle means it is easy to carry for one person.

The Engine

The engine on the Generac gp3000i packs a powerful punch while remaining a super quiet unit. It is a 149cc Generac 4-Stroke OHV engine that includes a low oil shutoff feature.

PowerDial Feature

The control panel of the generator Generac integrates start, run, stop functions into a PowerDial feature. This design means that every control falls on one simple to use dial. It allows for easy operation and a quick start-up process.

Outlets and Attachments

Part of the reason that the generator Generac is so convenient is that it has so many plug-in options. This versatility means that no device will be unable to connect.

You won’t have to load up on dozens of adapters to use your generator, either. It all comes on the unit, ready to use, just for the user.

The device includes two USB outlets:

  • 1-Amp USB outlet
  • 2.1-Amp USB outlet

These USB ports are perfect for plugging in a phone or tablet for quick and easy charging.

In addition to the USB ports, The Generac gp3000i includes three other essential outlets:

  • NEMA L5-30R 30 Amp 1-120 VAC outlet
  • NEMA 5-15R 15 Amp 1-120 VAC outlets (x2)

four different types of outlets

Along with the Generac gp3000i generator itself, the unit is parallel-ready. Users can purchase twice the power: parallel kit sold separately.

Make sure you purchase the parallel kit compatible with the gp3000i generator and not just Generac in general. Your unit has unique specifications that make it impossible to run without compatible equipment.

Advanced PowerRush Technology

This innovative inverter generator provides optimal performance, easy efficiency, and more. The advanced PowerRush technology delivers over 50% motor starting capacity.

It outperforms the competitors’ 25% starting capacity, allowing more efficient usage. It delivers twice the power as soon as you turn on the machine.

While your run time may be shorter when you operate at 50% instead of 25%, you can power larger electronics or more items at one time. It gives you the ability to customize your experience without feeling constrained by a low starting capacity.

Low Oil Alert and Shutoff

Low oil alert and shutoff are not present in every generator but should be. These features provide a decisive advantage against the number one problem in generators: wear and tear.

This feature lets you know when you are running low on oil. It automatically shuts the engine down so that it doesn’t continue to operate on low oil.

Running an inverter generator on low oil can damage the unit over time as it puts wear and damage on the engine. The alert and shutoff feature will, therefore, preserve the longevity of your portable generator.

The auto oil protection feature can prevent costly and frequent repairs and replacements. Investing in a device with this capability could end up saving you money.

Super Quiet Economy Mode

Loud generators can be disruptive, especially in RVs, where space is limited. Economy mode on the Generac gp3000i delivers super quiet inverter power perfect for small spaces or productive work sites.

The super quiet inverter power reduces sound emissions and provides optimal super quiet function. It also reduces fuel consumption, which keeps your fuel tank and your wallet full for longer.


Longer, 3-year warranties are ideal, but problems most often occur before the warranty 3-year mark, making a 2 or even 1-year option functional as customer support. If you are unsure of whether you want to add to cart, a good warranty can help.

This device offers two warranty packages depending on the type of buyer that you are:

  • Consumers get access to a lengthy 2-year warranty.
  • Commercial buyers get a shorter 1-year warranty that is still substantial.
