The PREDATOR® 4400W Max Starting, 3500W Running Inverter Generator uses built-in inverter technology to produce clean power ideal for sensitive electronics. The efficient design of this inverter generator gives you more power with lower fuel consumption, running over 16 hours per fill up. Electronic Speed Control Mode (ESC Mode) saves fuel and extends engine life. Quieter than conventional generators at only 67 dB(a) this inverter generator is ideal for camping, boating, and RV use with the included RV adapter.

  • CO SECURE™ technology automatically shuts down the generator for safety when harmful levels of carbon monoxide are detected
  • Pure sine wave inverter technology safely powers sensitive electronics such as smartphones, laptops, and TVs
  • Electronic Speed Control Mode (ESC Mode) optimizes engine performance to maximize runtime
  • Heavy duty steel frame and covered GFCI outlets are perfect for jobsite use
  • Integrated fuel gauge to easily monitor fuel levels
  • Low oil, overload, and output light indicators
  • Parallel ports for connecting two 4400W generators for double the power
  • Includes (4) 120v 20A GFCI protected outlets, 120v/30A twistlock, (2) USB ports
  • IMPORTANT INFORMATION: The PREDATOR® 4400W Max Starting, 3500W Running Inverter Generator is designed to run up to 29 Amps continuously, however, some appliances such as 13,500 BTU and 15,000 BTU air conditioners in recreational vehicles may require additional initial startup amperage. This model contains an overload sensor that will activate if it detects a spike above 45 Amps and will safely disable power output from the generator. Some customers have added a soft start capacitor to appliances that require such a large spike in amperage when starting up and those appliances with soft start are not affected by this generator’s overload sensor.
  • If this generator does not meet your specific appliance needs, you can return it for a full refund. Should you choose to return it, we offer many other generators that you can purchase which can accommodate appliances requiring higher initial startup amperage (above 45 Amps). These include the 3500 Watt Super Quiet Inverter Generator, 9500 Watt Super Quiet Inverter Generator, 8750 Watt Inverter Generator, 9000 Watt Generator, and 6500 Watt Generator.
