Overview of the Products

The Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator is significantly more powerful than the Westinghouse 6500 Watt Dual Fuel Home Backup Portable Generator, boasting higher peak and running wattage. With a peak output of 12,500 watts and running watts of 9,500, the 12500 model is designed for more demanding power needs. In contrast, the 6500 model provides 6,500 peak watts and 5,300 running watts, making it suitable for lighter applications. The price difference also reflects their capabilities, with the 12500 model priced at $999.00 compared to the 6500 model's $579.00, making the latter about 42% cheaper.

Power Output and Performance

When it comes to power output, the Westinghouse 12500 Watt model clearly outshines the 6500 Watt model. The 12500 generator can produce 12,500 peak watts and 9,500 running watts when fueled by gasoline, and 11,200 peak watts and 8,500 running watts on propane. This substantial power allows it to run multiple heavy-duty appliances simultaneously, such as air conditioners and refrigerators. Conversely, the 6500 model offers 6,500 peak watts and 5,300 running watts on gasoline, and 5,800 peak watts and 4,800 running watts on propane. While it can power essential devices, it may not handle as many large appliances at once as the 12500 model.

Fuel Efficiency and Runtime

The Westinghouse 12500 Watt generator provides a runtime of up to 12 hours on a 6.6-gallon fuel tank, which is quite efficient for its power output. Its ability to run for extended periods makes it ideal for prolonged outages or power needs. The 6500 Watt model, while less powerful, can run up to 14.5 hours on a 4.7-gallon fuel tank. This longer runtime makes it well-suited for less intensive tasks or short-term outages. Therefore, the choice between these two models may hinge on whether you prioritize power output or runtime.

Features and Usability

The Westinghouse 12500 Watt model comes equipped with a range of user-friendly features, including a remote start key fob and a digital hour meter for monitoring runtime and maintenance needs. It also has multiple outlet options, including a Transfer Switch Ready outlet, which is essential for powering home circuits during outages. The 6500 Watt model, on the other hand, includes a CO sensor for added safety and offers similar outlet options, albeit with lower wattage capabilities. Both generators are designed for plug-and-play use, minimizing assembly time, but the advanced features of the 12500 may appeal more to users with higher power demands.

Portability

Portability is a vital consideration for users who need to move their generators around frequently. The Westinghouse 12500 Watt generator includes heavy-duty never-flat wheels and a handle, making it relatively easy to transport despite its heavier weight due to the larger engine. The 6500 Watt model is also designed for portability, featuring a hardened steel frame and similar wheels for easy maneuvering. However, given its lighter weight and smaller size, the 6500 model may be easier to handle for users who need a more compact generator.

Safety Features

Safety features are crucial when dealing with powerful machinery like generators. The Westinghouse 6500 Watt model comes with a built-in carbon monoxide (CO) sensor, providing peace of mind during operation. The 12500 model also includes an automatic low oil shutdown feature, ensuring that the engine does not run dry and sustain damage. While both models prioritize safety, the presence of a CO sensor in the 6500 model could be a deciding factor for users concerned about indoor air quality during use.

Customer Support and Warranty

Both generators are backed by a 3-Year Limited Warranty and lifetime technical support from Westinghouse, ensuring customers receive assistance when needed. This commitment to service can be a significant advantage for buyers, especially those new to using generators. The 12500 model has a slightly better sales rank at 12,038 compared to the 6500 model's rank of 20,816, indicating a more favorable reception among users, which may reflect better customer satisfaction.

Which should you buy?

Choosing between the Westinghouse 12500 Watt and the 6500 Watt dual fuel generators largely depends on your specific power needs and budget. If you require high power output for multiple heavy-duty appliances and are willing to invest more, the Westinghouse 12500 Watt model is the superior choice. However, for those who need a more budget-friendly option with sufficient power for essential devices, the 6500 Watt model offers excellent value at about 42% less than its counterpart. Ultimately, evaluating your power requirements and budget will guide your decision.
