As the Generac GP3300i and the Predator 3500 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 Predator 3500 compare to the Generac GP3300i.

  • Engine: The 212cc engine of the Predator 3500 is significantly bigger than the Generac GP3300i's engine, which has a displacement of 149cc.
  • Power: With a running wattage of 3,000 W, the Predator 3500 will allow to power more appliances and tools than the 2,500 running watts of the Generac GP3300i. Moreover, compared to the 3,300 starting watts of the Generac GP3300i, the Predator 3500 and its starting wattage of 3,500 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 GP3300i: it can operate for up to 11 hours, whereas the Generac GP3300i offers a maximum runtime of 7 hours.
  • Fuel Efficiency: With a gasoline consumption at 25% load of 0.15 GPH (gallon per hour), the Generac GP3300i 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 (<5% for the Predator 3500 and <3% for the Generac GP3300i) 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 GP3300i 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 GP3300i is much lighter than the 102 lbs of the 3500.
  • Portability: As the Predator 3500 benefits from a built-in set of wheels, it is easier to move it once on the ground than the Generac GP3300i, because the latter doesn't have one. The Predator 3500 has a double handle and the Generac GP3300i a standard handle, to help you better manipulate them.

Feature Comparison

  • Starting System: These two devices can both be reliably started thanks to a conventional pull-start mechanism. However, the Predator 3500 also benefits from a convenient electric starter.
  • Outlets: The Predator 3500 and the Generac GP3300i both offer 3 AC outlets. None of them feature GFCI outlets. Both of them also feature a DC output. However, the Predator 3500 does not provide an out-of-the-box USB connectivity. In addition, it is worth noting that they both only produce 120V. For more detailed information regarding all their respective receptacles, refer to the Predator 3500's and the Generac GP3300i's product pages.
  • Data Center & Fuel Gauge: The Predator 3500 offers a better insight into its power production than the Generac GP3300i, because it is equipped with a data center. Besides that, thanks to a fitted fuel gauge, the Predator 3500 provides instant visibility of the fuel level.
  • Technology: They both benefit from a technology that monitors the ambient CO level. For the Predator 3500, it's the CO Secure technology, whereas it's the COsense® for the Generac GP3300i.
  • Warranty: The Generac GP3300i benefits from a significantly longer warranty. It is covered for up to 3 years, while the Predator unit is only covered for up to 90 days without purchasing a warranty extension.
