As the Predator 3500 and the Generac GP3000i do not share the same manufacturer, their overall build and technology in use can vary.

Power Comparison

The following charts are provided to show you at a glance how the main specs of the Generac GP3000i compare to the Predator 3500.

  • Power: With a running wattage of 3000 W, the Predator 3500 will allow to power more appliances and tools than the 2300 running watts of the Generac GP3000i. Moreover, compared to the 3000 starting watts of the Generac GP3000i, the Predator 3500 and its starting wattage of 3500 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 Predator 3500 offers a higher runtime on a full tank than the Generac GP3000i: it can operate for up to 11 hours, whereas the Generac GP3000i offers a maximum runtime of 5.8 hours.
  • Fuel Efficiency: With a gasoline consumption at 25% load of 0.18 GPH (gallon per hour), the Generac GP3000i is more fuel efficient than the Predator 3500 and its 0.24 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 GP3000i and <5% for the Predator 3500) and are therefore perfectly suitable to safely power your sensitive electronic devices.

Portability Comparison

  • Bulkiness: With dimensions of L22.2" x W13.3" x H18.4", the Generac GP3000i offers a much more compact experience of power generation than the Predator 3500 and its L22.8" x W17.3" x H20".
  • Weight: Weighing 59.5 lbs, the GP3000i is much lighter than the 99.2 lbs of the 3500.
  • Portability: As the Predator 3500 benefits from a wheel kit, it is easier to move it once on the ground than the Generac GP3000i, because the latter doesn't have one. The Generac GP3000i has a standard handle and the Predator 3500 a double handle, to help you better manipulate them.

Feature Comparison

  • Starting System: While these two devices can both start thanks to a conventional pull-start mechanism, the Predator 3500 has the advantage of also being able to get running via a convenient electric starter.
  • Outlets: The Generac GP3000i and the Predator 3500 both offer 3 AC outlets. None of them feature GFCI outlets. Both of them also feature a DC output. However, the Generac GP3000i does not provide an out-of-the-box USB connectivity. For more detailed information regarding all their respective receptacles, refer to the Generac GP3000i's and the Predator 3500's product pages.
  • Data Center: Being equipped with a data center, the Predator 3500 allows for a better monitoring of its power generation than the Generac GP3000i.
