Westinghouse 12500 Watt Dual Fuel
The Westinghouse 12500 Watt Dual Fuel generator provides 9500 running watts and 12500 peak watts on gasoline, plus 8500 running watts and 11200 peak watts on propane. It features remote start via a key fob, both electric and recoil start options, and a long 12-hour runtime on a 6.6-gallon tank with a fuel gauge. It includes outlets for standard 120V household power, a transfer switch ready 120V/240V option, and an RV-ready outlet. The unit uses a 457cc Westinghouse OHV engine with automatic low oil shutdown and a digital hour meter. A VFT display shows voltage, frequency, and lifetime hours.
Westinghouse 14500 Peak Watt Tri-Fuel
This Westinghouse model delivers 11,500 running watts on gasoline and up to 14,500 peak watts, with propane and natural gas options (10,500 running watts propane; 9,500 running watts natural gas). Powered by a 550cc engine, it can run up to 19 hours on a 9.5-gallon tank and up to 7 hours on a 20-pound propane tank. It’s designed for larger homes or dependable portable power with transfer switch readiness and multiple outlets guarded by safety features.
DuroMax XP13000EH
The XP13000EH provides 13,000 watts of power with dual-fuel versatility (gasoline and propane), and includes electric start for easy operation. It is marketed as a whole-home backup solution with transfer switch readiness and RV/emergency readiness. DuroMax emphasizes a robust engine and durability to sustain power during outages, with a design geared toward reliable, long-running performance in adverse conditions.
DuroStar DS13000MXT Tri-Fuel
The DS13000MXT delivers 13,000 watts and supports gasoline, propane, and natural gas. It includes a remote electric start and a wide power panel with a transfer switch-ready 50-amp outlet. The Tri-Fuel capability provides flexibility when fuel availability is limited, and its CO alert safeguards occupants by monitoring carbon monoxide levels during operation.
Westinghouse 13500 Peak Watt Tri-Fuel
With 10,500 running watts on gasoline and 13,500 peak watts, this tri-fuel unit also supports propane and natural gas. It includes remote electric start, transfer switch readiness, and multiple outlets with safety rubber covers. Its heavy-duty 500cc Westinghouse engine includes automatic low-oil shutdown and a digital hour meter for maintenance planning, making it a solid choice for mid-to-large homes needing flexible fuel options.
Buying Guide: Key Purchase Considerations
- Fuel options and availability: Dual- and tri-fuel models offer gasoline, propane, and sometimes natural gas. Consider which fuels are most accessible in your area and how available they are during emergencies.
- Power output and peak watts: Compare running watts (continuous power) and peak watts (surge power) to ensure the generator can handle your essential circuits. Larger homes typically need higher running watts.
- Runtime and fuel capacity: Check tank size and estimated runtimes at typical loads. Larger tanks extend run time between refuels but add weight and footprint.
- Start method and ease of use: Remote electric start and recoil options improve convenience during outages. A digital hour meter helps schedule maintenance before failures occur.
- Transfer switch readiness: Units with transfer switch compatibility simplify connecting to home circuits for safe, code-compliant power transfer.
- Outlets and safety features: Look for GFCI outlets, RV-ready outlets, and rubber outlet covers. CO sensors and low-oil shutdown protect occupants and equipment.
- Engine quality and durability: Cast-iron sleeves and OHV engines tend to offer longer life in harsh conditions. Consider displacement (cc) and cooling systems.
- Noise and footprint: Inverter-based models generally run quieter and use fuel more efficiently, but check noise ratings If noise is a concern for your neighborhood or campsite.
- Maintenance and support: Access to parts, warranty terms, and local service can affect long-term satisfaction and uptime during outages.
- Safety and compliance: Ensure unit placement complies with local clearance and ventilation requirements to prevent carbon monoxide buildup.
These models provide a range of power, fuel flexibility, and safety features suitable for American households. When selecting a generator, align your power needs with the unit’s running watts, consider fuel availability, and review transfer-switch compatibility to ensure a smooth, compliant setup during outages.
