Key Takeaways

  • WGen9500DF’s power output is commendable, effortlessly catering to a range of appliances and tools.
  • While its fuel efficiency and run time are in line with industry standards, it’s the generator’s adaptability to both gasoline and propane that elevates its performance profile.
  • The noise level, although slightly above the quietest models, remains within acceptable bounds for its power class.
  • Overall, for those prioritizing consistent and robust performance in a portable generator, the WGen9500DF proves to be a reliable choice.

Power Output

The Westinghouse WGen9500DF is undeniably a powerhouse in the portable generator market. Its impressive power output is one of its standout features, making it suitable for a variety of applications.

On gasoline, the generator boasts a continuous running wattage of 9,500W, with a surge wattage reaching up to 12,500W. This means it can comfortably handle most household appliances, tools, and even some heavy-duty equipment without breaking a sweat. For those opting to use propane, the WGen9500DF still delivers commendably with 8,500 rated watts and a starting wattage of 11,200W.

To illustrate the WGen9500DF’s capabilities, here’s a table demonstrating the simultaneous power output for various common appliances and tools when fueled by gasoline.

Item Running Watts Starting Watts
Refrigerator (18 cu.ft.) 150 1200
Window AC (10,000 BTU) 1200 3600
Portable Heater 1500 3000
Sump Pump (1/2 HP) 1050 2150
Washing Machine 1150 2300
Microwave Oven (1000W) 1000 2000
Television (LED) 150 300
Lights (5 x 60W bulbs) 300 300
Total 6500 14850

Such power output ensures that whether you’re facing a blackout at home, working on a construction site, or enjoying an RV trip, you won’t be left wanting for electricity. The generator’s capability to switch between gasoline and propane without a significant drop in power is a testament to its versatility and design excellence.

However, while its power output is substantial, it’s worth noting that there are a few generators in the market that might offer slightly higher wattages. But for its price range and other features, the WGen9500DF offers an excellent balance of power and functionality.

Run Time and Fuel Efficiency

Fuel efficiency and run time are critical factors when considering a portable generator, especially for prolonged use during power outages or extended work sessions. The Westinghouse WGen9500DF showcases commendable performance in these areas, though there’s room for improvement when compared to some competitors.

For fuel efficiency at 25% load, the WGen9500DF consumes 0.55 gallons per hour (GPH), which is on the higher end when compared to the average of 0.45 GPH. At 50% load, its consumption is 0.83 GPH, which is slightly better than the average of 0.85 GPH. This indicates that the generator is more fuel-efficient when operating at higher loads.

2 thoughts on “Westinghouse WGen9500DF Review: A Top-Performing Dual Fuel Generator”

  1. I was going to use the WGen9500DF as a home backup for power outages. However I keep hearing about the THD value being around 20%. I have read that most generators run between 10-20%. With all the sensitive electrical equipment (run by computers), would this be asking for trouble? The inverter generators are 5% THD or less the same as the large permanent home generators. What would you recommend purchasing an inverter or regular generator. Regards Jim1950

    1. Hi Jim,

      To power sensitive electronics, I recommend opting for an inverter generator. Take a look at the Genmax GM9000iED (7600 running watts), the Champion 100520 (7000 running watts) or the WEN GN875i (7000 running watts) if you’re seeking power output close to that of the WGen9500DF. Another option, which is slightly less powerful but still suitable for home power backup, is the WEN GN625i (5000 running watts).
