Wattage and Fuel Options Compared
Peak Wattage
Product B delivers 14,500 peak watts on gasoline, while Product A offers 13,500 peak watts. This 1,000-watt difference allows Product B to handle larger simultaneous loads. Both units provide 11,500 running watts on gasoline for Product B and 10,500 running watts for Product A. If you need maximum surge capacity for heavy appliances, Product B has the higher rating. This edge goes to Product B for its superior peak output numbers.
Fuel Flexibility
Product A is a tri-fuel generator, supporting gasoline, propane, and natural gas. Product B is dual-fuel, supporting only gasoline and propane. The ability to connect Product A to your home’s natural gas line means you can run it indefinitely without storing propane tanks or buying gasoline. Product B lacks this natural gas capability. For homeowners seeking the most versatile fuel options, Product A wins this round due to its third fuel source.
Propane Output
When running on propane, Product B provides 13,500 peak watts and 10,500 running watts. Product A drops to 12,500 peak watts and 9,500 running watts on propane. If you plan to use primarily propane for cleaner burning or easier storage, Product B maintains higher power output levels. Product B offers 1,000 more peak watts and 1,000 more running watts on this fuel type. This gives Product B a clear advantage in propane performance.
Engine Size
Product B features a 550cc engine, whereas Product A is equipped with a 500cc engine. The larger displacement in Product B aligns with its higher wattage ratings. Both engines are four-stroke OHV models with cast iron sleeves for durability. The extra 50cc in Product B suggests a design built for higher power demands. Product A’s smaller engine matches its lower wattage output. Product B takes this round for its larger engine specification.
Dimensions and Weight
Both generators weigh 230 pounds, making them similarly heavy to move. Product A measures 26.1 inches wide, 27.2 inches long, and 26.5 inches high. Product B is larger at 29.6 inches wide, 28.9 inches long, and 26.9 inches high. The extra width and length of Product B may require more storage space. Product A is more compact in its footprint. This is a tie in weight, but Product A is smaller. However, since weight is identical and size varies slightly, we call it a tie for practical handling.
Choose the right Westinghouse generator
You need the highest possible wattage
Product B offers 14,500 peak watts and 11,500 running watts on gasoline. This 1,000-watt advantage over Product A helps you power larger simultaneous loads. The 550cc engine supports this higher output. If your home requires maximum surge capacity, this dual-fuel model provides the extra headroom you need for heavy-duty backup.
You want flexibility with natural gas
Product A is a tri-fuel generator, allowing you to run on gasoline, propane, or natural gas. This option connects directly to a home's natural gas line for unlimited runtime. Product B only supports gasoline and propane. If you have access to natural gas infrastructure, this model offers a more versatile and potentially endless power solution.
You prioritize compact dimensions
Product A measures 26.1 inches wide and 27.2 inches long. Product B is wider at 29.6 inches and longer at 28.9 inches. Both weigh 230 pounds. If you have limited storage space in a garage or shed, the smaller footprint of the 13500W model makes it easier to fit into tighter areas without sacrificing essential features.
