  • High Power Output: The Westinghouse 9500df offers a power output of 7500W and 9500W when running on gasoline, 6750W and 8550W when running on propane. This substantial power is sufficient to operate several household appliances simultaneously. The power output can sustain light commercial devices, such as drills, grinders, and welding machines.
  • Efficiency: This generator is powered by a 420cc air-cooled OHV engine that achieves an impressive 11 hours of operation on a 6.6-gallon (25 liters) tank at 50% load. This fuel efficiency is notable, especially considering the high-power output that this generator delivers. 
  • Enhanced Safety: The carburetor injection system on the Westinghouse 9500df features an automatic low oil shutdown mechanism that promptly shuts off the engine when low oil pressure is detected, thereby protecting the engine from damage. Other safety features accompanying this generator include automated voltage regulation, a high-sensitivity circuit breaker, surge protection, and rubber outlet covers. 
  • Versatile Output Options: The Westinghouse dual fuel generator powers a wide range of devices. The manufacturer has integrated several outlets, including two 120V-GFCI household outlets, one 120/240V 30-amp twist-lock output, and a 12V DC battery charger. These options allow for easy connection to any device you wish to power. 
  • Friendly User Interface: The control panel of this generator is intuitively designed and arranged to enhance safety and control. The VFT data center, main circuit breaker, battery indicator, engine start/stop button, electric start button, smart switch, and power outlets are neatly organized on a single panel. This arrangement makes the generator very user-friendly.

Cons of the Westinghouse 9500df

  • Reliability and starting issues: Everyone has unique experiences with machinery and 75% of the Amazon reviews are good 5 star ratings besides one’s own experience. This gives this generator and overall rating of 4.6 at this writing with thousands purchased. But for 25% of customers, they have trouble starting this generator. So for emergency preparedness, power outages, and very cold temperatures (-20C) you might look at one of our other recommendations.
  • Bad Westinghouse and Amazon Customer Support: If the generator does not work properly, Amazon will not send you a new one. The next option is to take it to an authorized Westinghouse distributor or repair location if you have one near you. Not always good in rural areas. Reviews of Westinghouse repeated and monotonous customer support 20 to 30 minutes hold times from phone contact.
  • Quite Heavy: The Westinghouse Outdoor Power Equipment 9500 is substantially heavy due to its size and robust steel construction. Weighing in at 201 pounds, this generator is nearly impossible to lift. Fortunately, it comes with a wheel and handle kit to facilitate easier maneuverability across various terrains. The 8-inch wheels navigate over grass effortlessly and with minimal struggle.
  • Quite Noisy: The 420cc engine tends to be noisy. At a half load of operation, the generator emits about 72 dBA, which can be loud, especially in densely populated environments. However, the noise is significantly reduced when the generator operates outside a house.
  • Sensitivity to Gasoline Quality: This generator has shown sensitivity to the quality of gasoline used. Some users have reported experiencing hard starts and erratic engine performance when using regular and mid-grade gasoline with octane ratings below 91. The generator performs optimally with premium-grade gasoline, boasting octane ratings above 92. The workaround for this issue is to ensure the use of high-quality fuel.
  • Requires Initial Assembly and Setup: Some assembly and setup are required before this generator is ready for use. Although these assembly steps are clearly detailed in the user manual and are generally DIY-friendly, some individuals might find it necessary to have an electrician handle the assembly.
