Key differences
| Aspect | Westinghouse 12500W Gas Generator with Remote Start | Westinghouse 13500W Tri-Fuel Portable Generator |
|---|---|---|
| Fuel Type | Gasoline only | Tri-Fuel (Gas, Propane, Natural Gas) |
| Running Watts | 9500W | 10500W (Gas); 9500W (Propane); 8500W (NG) |
| Engine Size | 457cc | 500cc |
| Fuel Tank Capacity | 6.6 Gallons | 9.5 Gallons |
| Weight | 212 pounds | 230 pounds |
Which one should you choose?
Choose Westinghouse 12500W Gas Generator with Remote Start if
- You only have access to gasoline and want a lighter unit at 212 pounds.
- You prefer a smaller fuel tank that requires less space on your property.
- You need a generator with a 457cc engine that is simpler to maintain.
Choose Westinghouse 13500W Tri-Fuel Portable Generator if
- You need the highest possible running wattage of 10500W on gasoline.
- You want the flexibility to switch between gas, propane, and natural gas.
- You require a longer run time of up to 19 hours on a full tank.
Verdict: Choose the 12500W model if you prefer a lighter, gasoline-only generator with a smaller footprint. The 13500W Tri-Fuel model is the better choice if you need higher power output and the flexibility to use propane or natural gas for extended run times.
Power Output and Fuel Flexibility
Peak Wattage Output
The Westinghouse 13500W Tri-Fuel Portable Generator delivers 13500 peak watts on gasoline, while the Westinghouse 12500W Gas Generator Remote provides 12500 peak watts. Both units offer the same 9500 running watts when using gasoline. If you need the highest possible surge capacity for starting large motors, the 13500W model gives you an extra 1000 watts of peak power. This difference matters mostly for equipment with high startup demands. The 12500W model is sufficient for standard home backup loads, but the 13500W model offers a slight margin for heavier industrial or construction tools.
Fuel Type Options
Fuel flexibility is a major distinction between these two generators. The Westinghouse 13500W Tri-Fuel Portable Generator runs on gasoline, propane, or natural gas. This allows you to switch fuels based on availability or storage convenience. The Westinghouse 12500W Gas Generator Remote operates exclusively on gasoline. If you have access to a natural gas line or prefer storing propane tanks, the tri-fuel option provides significant operational versatility. Gasoline-only models are simpler but lack the backup fuel options that the tri-fuel unit offers for extended outages.
Running Wattage by Fuel
When running on fuels other than gasoline, the power output changes. The Westinghouse 13500W Tri-Fuel Portable Generator produces 10500 running watts on gasoline, 9500 on propane, and 8500 on natural gas. The Westinghouse 12500W Gas Generator Remote provides 9500 running watts on gasoline only. If you plan to run the generator on propane or natural gas for long-duration use, the 13500W model still maintains a higher output than the gasoline-only counterpart. This makes the tri-fuel unit more powerful across all fuel types.
Run Time Capacity
Fuel tank size directly impacts how long each generator can operate before refueling. The Westinghouse 13500W Tri-Fuel Portable Generator features a 9.5-gallon fuel tank, providing up to 19 hours of run time. The Westinghouse 12500W Gas Generator Remote has a smaller 6.6-gallon tank, offering up to 12 hours of run time. The larger tank on the 13500W model means fewer refueling interruptions during extended power outages. Both units include a fuel gauge to monitor levels, but the extra capacity in the tri-fuel model is a clear advantage for longer standby periods.
Engine Displacement
Engine size often correlates with durability and power potential. The Westinghouse 13500W Tri-Fuel Portable Generator is powered by a 500cc 4-stroke OHV engine. The Westinghouse 12500W Gas Generator Remote uses a 457cc 4-stroke OHV engine. Both engines feature cast iron sleeves for longevity and include automatic low-oil and carbon monoxide shutdowns. The larger 500cc engine in the 13500W model supports its higher wattage output. While both are heavy-duty, the 500cc engine provides more mechanical capacity to handle the increased electrical load.
Which Westinghouse Generator Fits Your Needs
Users needing maximum power and fuel flexibility
You should choose this model for its higher peak output of 13,500 watts on gasoline. It also supports propane and natural gas, offering three fuel options. The 9.5-gallon tank provides up to 19 hours of runtime. This extra capacity and flexibility make it ideal for extended power outages or diverse fuel availability.
Buyers preferring lighter weight and simpler operation
Select this generator if you prioritize portability and straightforward use. It weighs 212 pounds, which is 18 pounds lighter than the tri-fuel alternative. It runs solely on gasoline, eliminating the need to manage multiple fuel types. The 6.6-gallon tank still offers 12 hours of runtime, providing a reliable balance of power and ease of transport.
Those prioritizing engine longevity and safety features
This unit features a larger 500cc engine compared to the 457cc engine in the other model. Both include automatic low-oil and carbon monoxide shutdowns. The larger engine may offer better durability under heavy loads. You also get transfer switch readiness and remote start on both, ensuring consistent safety and convenience for home backup applications.
