Westinghouse 6500 Watt Dual Fuel Generator
The Westinghouse 6500 Watt Dual Fuel Generator offers gasoline and propane operation with dual 30A outlets and a 30A transfer switch-ready receptacle. It runs 5300 watts on gasoline and 4800 watts on propane, with a 4.7-gallon fuel tank and a fuel gauge for planning. Best for homeowners and RV users who need reliable backup power with a simple plug-and-play setup. Reserve this model if you want a generator that’s transfer-switch ready and RV-capable. A noted limitation is lower propane running watts compared to gasoline, so plan fuel accordingly for higher-load tasks.
WEN 8000-Watt Dual Fuel Portable Generator
The WEN DF8000X provides 8000 surge watts and 6500 running watts from gasoline, plus 7200 surge and 5850 running watts from propane. It features electric start, a CO watchdog, and is designed for transfer-switch owners who want a robust backup power source. Best for medium to large homes or job sites where higher continuous power is beneficial. A caveat is the higher noise and size typical of larger units, which may affect portability.
WEN 5600-Watt Dual Fuel Portable Generator
The WEN DF5600X delivers dual-fuel capability with gasoline at 4500 running watts (5600 surge) and propane at 4050 running watts (5000 surge). An electric start and CO shutdown sensor help simplify operation and safety. This model is best for small to midsize homes or campers needing dependable backup with a smaller footprint. Consider this option if you want a lighter, more portable dual-fuel generator and you do not need maximum power for heavy electricity loads.
Westinghouse 13500 Peak / 10500 Running Dual Fuel
This model supports up to 19 hours of run time on a 9.5-gallon tank and includes a variety of outlets: two 20A 5–20R receptacles, a transfer switch-ready 120V L14-30R, and an RV 50A 14–50R. It uses a 500cc Westinghouse OHV engine and includes a digital hour meter for maintenance planning. Best for residences with higher power needs or remote work setups. A limitation is its larger size and weight, which reduces portability.
Westinghouse 6600 Watt Dual Fuel Portable Generator
The Westinghouse 6600 Watt model offers gasoline at 5300 running watts and 6600 peak watts, propane at 4800 running watts and 5900 peak watts, and a push-button electric start with remote key fob. It includes a 4.7-gallon tank with a fuel gauge and multiple outlets with safety covers. Best for homeowners who want a strong, remote-start backup with versatile fuel options. Limitations include the potential need for regular maintenance and occasional refueling during extended outages.
WEN 6800-Watt Dual Fuel Inverter Generator
The WEN DF680iX provides 6800 surge watts and 5100 running watts on gasoline, 6000 surge and 4500 running watts on propane, with an inverter configuration suitable for sensitive electronics. It includes a CO watchdog sensor for safety. Best for users who need portable, clean power for electronics in RVs or small workshops. A limitation is that inverter generators often have lower continuous power than non-inverter counterparts, so plan for peak loads accordingly.
Westinghouse 14500 Peak Watt Dual Fuel
This larger Westinghouse model targets bigger homes or more extensive portable power needs, delivering up to 11,500 running watts (gas) and 10,500 running watts (propane) with a long runtime. It offers remote electric start and multiple outlets, including a 50A RV receptacle. Best for substantial whole-house backup or heavy-duty off-grid use. Caution: It’s heavy and not suitable for tight spaces or narrow pathways.
Buying Guide
- Power needs: Determine your essential loads and total watts to avoid overload. Look for models with at least a 1.2x safety margin over your peak need.
- Fuel availability and consumption: Propane is convenient and long-lasting; gasoline typically offers higher running watts but shorter storage life. Consider tank size and run-time requirements.
- Transfer switch compatibility: If connecting to a home panel, ensure the generator includes a transfer switch-ready outlet and adheres to local electrical codes.
- Portability vs. capacity: Larger units deliver more power but are heavier. For RVs or frequent transport, prioritize lighter, more compact options with wheels and handles.
- Safety features: Look for CO shutoff sensors, rubber outlet covers, and sturdy frames. An automatic CO detector can prevent harmful exposure during operation.
- Outlet configuration: Confirm the presence of common outlets (5–20R) and RV-specific outlets (TT-30R or 14–50R) to fit your devices and camper hookups.
- Starting method: Electric start improves ease of use; recoil start remains reliable in a power outage but can be less convenient in cold weather.
Frequently Asked Questions
- What is the difference between running watts and peak watts? Running watts describe continuous power output; peak watts indicate maximum surge power for startup of appliances.
- Do dual-fuel generators support 240V operation? Yes, most dual-fuel models provide 120V and 240V configurations compatible with transfer switches and RV setups.
- Is CO shutdown essential? CO shutdown helps automatically turn off the generator if dangerous carbon monoxide levels are detected, improving safety in enclosed spaces.
- How long will a full tank run typically? Run-time varies by model, load, and fuel; many units offer up to 14–19 hours at lighter loads with larger tanks.
- Can I run these indoors? Generators emit carbon monoxide; always operate outside in a well-ventilated area away from doors and windows.
- What maintenance should I perform? Regularly check oil levels, inspect spark plugs, and replace air filters as recommended by the manufacturer to extend life.
