Key Takeaways

  • The DuroMax XP12000EH has 9,500W running with both L14-30R and 14-50R outlets and a CO sensor.
  • The Westinghouse WGen7500DF has 7,500W running with L14-30R and remote start but NO CO sensor.
  • The DuroMax has 19-hour runtime vs 11-hour for the Westinghouse.
  • The DuroMax is louder at 74 dBA vs 72 dBA for the Westinghouse.
  • Choose DuroMax for maximum power and CO safety; choose Westinghouse for value and remote start.

The Short Answer

The DuroMax XP12000EH delivers 9,500W with L14-30R, 14-50R, a CO sensor, and 19-hour runtime — the most capable whole-house dual-fuel generator. The Westinghouse WGen7500DF offers 7,500W with L14-30R and remote start at a lower price but lacks a CO sensor. Choose DuroMax for maximum power and safety; choose Westinghouse for value and convenience if you add a separate CO alarm.
