As the Predator 3500 and the Generac GP3500iO 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 GP3500iO compare to the Predator 3500.

  • Power: As both the Generac GP3500iO and the Predator 3500 share the same running wattage of 3000W, they will both allow you to simultaneously power the same appliances. In addition, as the 2 generators have the same starting watts (3500 W), they will both give you the same boost needed to start the motor of your most demanding appliances.
  • Runtime: At a 25% load, these 2 portable generators offer the same runtime on a full tank. Each of them will be able to deliver power for up to 11 hours.
  • Fuel Efficiency: With a gasoline consumption at 25% load of 0.22 GPH (gallon per hour), the Generac GP3500iO 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 GP3500iO and <5% for the Predator 3500) and are therefore perfectly suitable to safely power your sensitive electronic devices.

Portability Comparison

  • Bulkiness: With dimensions of L19.3" x W16.9" x H16.4", the Generac GP3500iO offers a much more compact experience of power generation than the Predator 3500 and its L22.8" x W17.3" x H20".
  • Weight: Weighing 74.3 lbs, the GP3500iO 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 GP3500iO, because the latter doesn't have one. To the contrary of the Generac GP3500iO, the Predator 3500 benefits from a double handle, to help you get a better grip anytime you wish to move your portable generator.

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 GP3500iO and the Predator 3500 both offer 3 AC outlets. None of them feature GFCI outlets. Both of them also feature a DC output. For more detailed information regarding all their respective receptacles, refer to the Generac GP3500iO's and the Predator 3500's product pages.
  • Data Center: Each of these 2 portable generators is equipped with a data center allowing you to conveniently monitor some aspects of the power output.
