WEN 6800-Watt DF680iX

The WEN DF680iX offers dual-fuel capability and an electric start for quick power in emergencies. It runs on gasoline with 6800 surge watts and 5100 running watts, or propane with 6000 surge watts and 4500 running watts. A bonded-neutral 240V configuration supports low-power Level 2 charging for certain EVs and hybrids. The built-in CO watchdog sensor helps protect occupants by automatically shutting down the unit if dangerous carbon monoxide levels are detected. Compact enough for portable use, it serves well for RVs and home backup scenarios.
Westinghouse 14500 Peak Watt Tri-Fuel

This tri-fuel powerhouse provides versatile fuel options: gasoline, propane, or natural gas. It delivers up to 14,500 peak watts and 11,500 running watts on gasoline, with propane and natural gas variants at slightly different outputs. A heavy-duty 550cc Westinghouse engine underpins long runtimes, and the unit is designed for transfer switch readiness. Features such as a fuel gauge and multiple outlets make it suitable for larger homes or job sites where dependable backup power is essential.
DuroStar DS13000MX 13,000-Watt

The DS13000MX delivers strong dual-fuel performance with remote electric start for quick operation. It can power homes, work sites, or RVs during outages and storms. Dual fuel capability ensures you can opt for gasoline for maximum power or propane for longer run times and easier fuel storage. It also includes a CO alert for enhanced safety, automatically shutting down if dangerous fumes are detected, which is important for enclosed spaces or garages.
WEN DF5600X 5,600-Watt

The DF5600X is a smaller but capable dual-fuel option with an electric start and a CO watchdog sensor. It offers 5,600 surge watts and 4,500 running watts on gasoline, plus slightly lower outputs on propane. This model emphasizes portability and quiet operation, making it well-suited for home backup in tighter spaces, RV use, and camping trips where noise reduction matters.
Westinghouse 12500 Watt Dual Fuel

With a focus on home backup readiness, this Westinghouse model delivers 12,500 peak watts and 9,500 running watts on propane, and 12,500 peak / 11,500 running watts on gasoline. It includes remote start and transfer switch readiness for easy integration with home electrical systems. Its 6.6-gallon fuel tank and digital hour meter provide long runtimes and real-time status, while multiple outlets, including RV-ready and NEMA configurations, support various devices and appliances.
Westinghouse 14500 Peak Watt Dual Fuel (Outdoor Power)

This model emphasizes outdoor use with dual-fuel capability (gasoline and propane) and a high peak wattage for larger power needs. It’s designed for longer runtimes on substantial tanks and provides a robust backup option for bigger homes or extended outdoor sites. Features like remote electric start and transfer-switch readiness support seamless power management during outages.
PowerSmart 4400-Watt Dual Fuel

The PowerSmart 4400-Watt dual-fuel inverter generator emphasizes a compact, lightweight design with a dual-fuel output of 4,400 starting watts and 3,600 running watts on gasoline, plus propane options. It features a CO sensor and EPA compliance, making it a practical option for home use, camping, or emergency backup. Its quieter operation and smaller footprint suit portable scenarios where space and noise are concerns.
Buying Guide: Key Purchase Considerations
- Power needs: Assess peak and running watts for essential appliances and devices. Choose a generator with a buffer above your calculated requirements to handle startup surges.
- Fuel flexibility: Dual-fuel models offer gasoline and propane backups. Consider fuel availability, storage, and the run-time you need between refuels.
- Safety features: Look for CO shutoff (CO watchdog), automatic low-oil shutdown, and enclosure design that minimizes fumes in living areas. A remote start or electric start improves ease of use during power outages.
- Portability and noise: Inverter generators with quiet operation are ideal for campgrounds or tight spaces. Weight, wheel kits, and ergonomic handles influence transportability.
- Electrical compatibility: Check 120V vs 120/240V outputs, transfer-switch readiness, and compatibility with your home’s electrical panel or RV inlet.
- Reliability and maintenance: Engine type, fuel economy, run time per tank, and service support impact long-term performance and ownership costs.
- Environmental and safety considerations: Emission standards (EPA), noise regulations at your location, and safe storage practices for gasoline and propane.
