- Why selected: Dual-fuel flexibility with a practical control panel and remote start.
- Caution: Propane may yield lower peak power than gasoline; plan for essential circuits first.
DuroStar DS13000MX Dual-Fuel Generator
The DS13000MX delivers a robust 13,000 watts total with dual-fuel capability for gasoline or propane. It is built for whole-home power backup, with a heavy-duty frame and a design geared toward transfer switch readiness. Propane use extends run times and reduces emissions, making it a strong candidate for areas with fuel supply considerations during outages. A notable caution is the unit’s size and weight; it is best suited for stationary installation or frequent heavy-duty use rather than frequent portabilit
- Best for: Serious home backup or job-site power with transfer switch readiness.
- Why selected: High wattage capacity with dependable dual-fuel flexibility.
- Caution: Large footprint and heavy to move without proper handling gear.
Westinghouse 12500 Dual Fuel Home Backup Generator
The Westinghouse 12500 offers 9500 running watts and 12500 peak watts on gasoline, with propane output of 8500 running watts and 11200 peak watts. Remote start with a key fob adds convenience for quick outages, and the unit includes multiple outlets, including a 50A RV-ready receptacle and transfer switch readiness. Its VFT display keeps you informed of voltage, frequency, and runtime. This model is ideal for larger homes or remote job sites needing substantial, versatile power. A limitation is higher fuel consumption under full load compared to smaller units.
- Best for: Large homes or demanding sites needing ample dual-fuel power.
- Why selected: High wattage, comprehensive outlets, and remote start capability.
- Caution: Heavier and more fuel-demanding; plan fuel storage and maintenance accordingly.
Westinghouse 6600 Watt Dual Fuel Generator

It supports 120V and 240V with a transfer-switch-ready setup and a remote key fob for convenient starts. This unit is a solid fit for medium-sized homes and contractors who need reliable dual-fuel power with decent runtime. Limitations to consider include noise level and size, which may require a stable outdoor setup and proper placement away from living spaces.
- Best for: Medium-sized homes and backup power with transfer switch compatibility.
- Why selected: Balanced wattage, strong runtime, and wide outlet selection.
- Caution: Loud operation; use outdoors and follow local noise guidelines.
Buying Guide: Key Considerations for Propane-Powered Dual-Fuel Generators
Fuel flexibility: Dual-fuel generators let you run on propane or gasoline. Propane offers longer shelf-life and cleaner emissions, while gasoline provides higher peak power. Consider which fuel is more accessible and economical for your location and usage pattern.
Power output and transfer switch readiness: Match running and peak watts to your essential loads. If you plan to power a whole home, look for higher continuous watts and a unit designed for turnkey transfer-switch installations. RV and outdoor uses benefit from outlets configured for common needs, like 30A RV receptacles and multiple 120V outlets.
Starting method and convenience: Electric start with a key or push-button is a major convenience during outages. Remote start adds a level of control from a distance, which can be valuable for preheating or ensuring readiness before an outage hits.
Runtime and fuel capacity: Larger tanks provide longer runtimes, but they also affect weight and space. Consider your typical outage duration and your ability to refuel safely. CO sensors and low-oil shutoffs add safety for unattended operation or family use.
Portability vs. permanence: Inverter generators tend to be quieter and lighter, ideal for camping and RV use, while heavier, higher-wattage units are often deployed as semi-permanent backup solutions with transfer switches. Choose based on how often you’ll relocate or where you’ll place the generator.
Outlets and safety features: Look for a mix of 120V and 240V outlets, RV outlets, and robust protective features like CO sensors and automatic shutdown. Rubber outlet covers increase weather resistance for outdoor setups.
Frequently Asked Questions
- What does “dual fuel” mean for these generators?
Dual fuel means the unit can run on both gasoline and propane, offering flexibility during fuel shortages or storage concerns.
- Is propane a good choice for home backup?
Propane can be a cleaner-burning option with a longer shelf life, making it practical for long-term storage and regular standby use.
- Do these generators require transfer switches?
For whole-home backup, a transfer switch is recommended to safely isolate the generator from utility power and protect circuits.
- How do I estimate the power I need for essential loads?
List critical devices (refrigerator, lights, modem, well pump) and sum their watts. Choose a model with a running watt capacity above your total while leaving headroom for startup surges.
- What safety features should I look for?
CO sensors, automatic shutdown on low oil, and proper grounding are important for safe operation, especially in residential settings.
- Can I run multiple generators in parallel?
Some models support parallel operation with compatible kits, enabling higher total output. Check the specific model’s compatibility.
