As the iQ2000 and the GP3000i are both Generac generators, they benefit from the same level of quality and attention to detail.

Power Comparison

The following charts are provided to show you at a glance how the main specs of the Generac iQ2000 compare to the Generac GP3000i.

  • Power: With a running wattage of 2300 W, the Generac GP3000i will allow to power more appliances and tools than the 1600 running watts of the Generac iQ2000. Moreover, compared to the 2000 starting watts of the iQ2000, the GP3000i and its starting wattage of 3000 W will give more power to start the appliances which require an additional boost to get their motor running.
  • Runtime: When loaded to 25% of their max capacity, the iQ2000 offers a higher runtime on a full tank than the GP3000i: it can operate for up to 7.7 hours, whereas the GP3000i offers a maximum runtime of 5.8 hours.
  • Fuel Efficiency: With a gasoline consumption at 25% load of 0.14 GPH (gallon per hour), the Generac iQ2000 is more fuel efficient than the GP3000i and its 0.18 GPH. The former's operation will therefore cost less in terms of the money spent on gasoline. Inverter generators like these 2 are of the most fuel efficient (and quiet) type.
  • THD: Both generators offer a low THD (<3% for the Generac iQ2000 and <3% for the Generac GP3000i) and are therefore perfectly suitable to safely power your sensitive electronic devices.

Portability Comparison

  • Bulkiness: With dimensions of L20" x W12.6" x H16.9", the Generac iQ2000 offers a much more compact experience of power generation than the Generac GP3000i and its L22.2" x W13.3" x H18.4".
  • Weight: The iQ2000 and its 46.5 lbs is somewhat lighter than the 59.5 lbs of the GP3000i.
  • Portability: Both offer a handle, which improves your grip when you wish to move them around.

Feature Comparison

  • Starting System: Both devices can get running via a conventional pull-start mechanism.
  • Outlets: With a total of 3 AC outlets, the GP3000i offers more AC receptacles than the iQ2000, which has 2 AC outlets. None of them feature GFCI outlets. The latter also offers a DC output. For more detailed information regarding all their respective receptacles, refer to the iQ2000's and the GP3000i's product pages.
  • Data Center & Fuel Gauge: The Generac iQ2000 offers a better insight into its power production than the Generac GP3000i, because it is equipped with a data center. Besides that, thanks to the digital fuel fauge provided by its data center, the Generac iQ2000 provides instant visibility of the fuel level.
