Westinghouse 12500 Watt Dual Fuel Generator

Powered by a robust 457cc Westinghouse engine, this model supports both gasoline and propane with high peak and running wattage. It offers remote electric start via key fob, plus multiple outlets including GFCI 120V and a 30A transfer switch-ready receptacle. A digital hour meter and VFT display provide real-time voltage, frequency, and runtime data. The unit features a heavy-duty build with a cast iron sleeve and automatic low oil shutdown for safety. Overall, it suits larger homes needing substantial backup power and transfer switch integration.
Westinghouse 6500 Watt Dual Fuel Generator

This compact dual-fuel option focuses on essential home backup with a 4.7-gallon tank and long runtime. It provides 5300 running watts on gasoline and 4800 running watts on propane, with a 14.5-hour run time mentioned for typical loads. It includes multiple receptacles (5–20R, TT-30R, L14-30R) and a transfer switch-ready outlet. Rubber outlet covers enhance safety, and it ships with oil and a basic toolkit for quick setup. Ideal for mid-size homes or cabins where portability matters.
DuroStar DS13000MX

With 13,000 total watts on gasoline and 10,000 watts on propane, the DS13000MX delivers strong whole-home backup capability. It is designed for dual-fuel use, enabling flexibility during outages. A CO alert system provides enhanced safety by shutting down the unit if gas levels rise. The generator is built for heavy-duty performance and includes transfer switch readiness, making it suitable for larger homes or job sites requiring consistent power supply during emergencies.
Westinghouse 14500 Peak Watt Dual Fuel

Designed for larger homes or serious portable power, this model delivers 11,500 running watts on gasoline and 13,500 peak watts on propane. It supports natural gas as well with 12,000 peak watts and 9,500 running watts. A heavy-duty 550cc Westinghouse engine powers a long runtime—up to 19 hours on a full tank and about 7 hours on a standard 20-lb propane tank. It is remote-start capable and transfer switch-ready, making it a strong option for whole-house reliability in outages.
DuroStar DS13000MXT Tri Fuel

The DS13000MXT expands fuel flexibility with tri-fuel capability (gas, propane, natural gas) for continued operation during various fuel shortages. It delivers 13,000 watts on gas and supports transfer switch readiness and RV-ready outlets for broader compatibility. A push-button start and a CO alert system add ease of use and safety. This model is designed for larger homes or locales that require extensive backup power and fuel versatility across multiple fuel sources.
Buying Guide: Key Purchase Considerations
- Power needs: Assess both running and peak wattage for essential circuits, HVAC, and appliances. Choose a model with a comfortable buffer above your calculated load.
- Fuel flexibility: Dual fuel and tri fuel options offer resilience during fuel shortages. Propane generally stores longer than gasoline, but fuel availability matters in your area.
- Transfer switch readiness: If you plan to connect to a home panel, ensure the unit is transfer switch ready and compatible with your panel capacity and RV/outlet needs.
- Safety features: CO sensors, automatic shutdown, and rubber-outlet covers are important for indoor or semi-indoor use. Remote starts improve convenience during cold starts.
- Runtime and tank size: Larger tanks yield longer operation at a given load. Compare run times at typical loads to estimate refill frequency.
- Noise and portability: Some models emphasize quieter operation; weight and wheel kits affect how easily you can move the unit around your property.
- Outlets and versatility: Look for a mix of 120V and 240V, RV-ready outlets, and a dedicated transfer switch connection if you want whole-house coverage.
- Maintenance and support: Consider warranty terms, availability of replacement parts, and customer service when selecting a model for long-term use.
