Westinghouse 12500 Watt Dual Fuel Generator
The Westinghouse 12500-watt dual‑fuel generator delivers substantial power for mid to large homes. It runs on gasoline with 9500 running watts and 12500 peak watts, or propane with 8500 running watts and 11200 peak watts. A remote start with a key fob provides quick operation during emergencies, and it includes safety features such as an automatic low oil shutdown. The unit is transfer switch ready, with outlets including a 120V household receptacle, a 120/240V 50A outlet, and an RV ready 50A outlet. A digital hour meter and VFT display provide real-time output data.
Westinghouse 14500 Peak Watt Tri-Fuel Generator
Designed for larger homes, this tri‑fuel backup unit supports gasoline, propane, and natural gas. It provides up to 11,500 running watts (gas) and 13,500 peak watts, or 10,500 running watts (propane) and 12,000 peak watts (natural gas). A heavy‑duty 550cc Westinghouse engine powers long runtimes—up to 19 hours on a full 9.5‑gal tank with a fuel gauge, and about seven hours on a 20‑lb propane cylinder. Transfer switch readiness and multiple outlets accommodate whole‑house circuits while maintaining safety and reliability.
WEN 4,750-Watt Dual Fuel Portable Generator
The WEN DF475T offers a compact dual‑fuel option with 4750 surge watts and 3800 running watts on gasoline, or 4350 surge and 3500 running watts on propane. Its voltage range covers 120V to 240V, making it suitable for transfer switches and basic backup needs. An electric start simplifies operation, powered by a 224cc 4‑stroke OHV engine. Wheel kit included for portability. This model balances price with dependable performance for small to mid‑sized homes or essential circuits during outages.
WEN 6800-Watt Dual Fuel Inverter Generator
The WEN DF680iX is an inverter generator designed for versatility and efficiency. It provides 6800 surge watts and 5100 running watts on gasoline, or 6000 surge watts and 4500 running watts on propane. It features a bonded‑neutral 240V configuration that supports low‑power Level 2 charging for electric vehicles and battery systems. The CO watchdog sensor enhances safety by automatically shutting down the unit if carbon monoxide is detected. This model suits households seeking reliable, quieter power with modern safety features for mixed‑fuel use and EV readiness.
DuroStar DS13000MX 13,000-Watt Dual Fuel
The DuroStar DS13000MX delivers about 13,000 watts of power with dual‑fuel capability for flexibility in outages. It’s designed as a whole‑home backup option and is transfer switch ready. The unit supports gas and propane and emphasizes safety with a CO alert that shuts down the generator if dangerous fumes are detected. A robust build and remote electric start provide convenient operation during outages, making it a strong candidate for larger homes or job sites requiring resilient power.
Buying Guide: Key Purchase Considerations
- Power output and load: Determine essential circuits versus whole‑home needs. Compare running and peak watts to ensure the generator can handle startup surges of appliances like refrigerators and air conditioners.
- Fuel type and efficiency: Dual‑fuel units offer flexibility during fuel shortages. Consider runtimes on a full tank and the ease of refueling during outages.
- Starting method: Remote/electric start speeds up response in emergencies. Manual recoil start is a reliable fallback if electronics fail.
- Transfer switch compatibility: A transfer switch prevents backfeeding and enables utility‑grid isolation, protecting service technicians and your equipment.
- Safety features: Look for low‑oil shutdown, spark arrestors, and CO sensors or shutdowns to protect occupants from fuel fumes and carbon monoxide.
- Noise and portability: Inverter designs lessen noise and provide cleaner power for sensitive electronics. Wheel kits improve mobility on uneven surfaces.
- Maintenance: Regular oil changes, air filter care, and scheduled service extend life and reliability.
- Warranty and support: Check warranty length and access to parts and service centers in the United States for quick repairs after outages.
When selecting a backup generator, balance power needs with budget and space constraints. Larger homes benefit from higher wattage and multi‑fuel capability, while smaller households may prioritize portability and essential circuit coverage. The models listed provide a spectrum of options—from heavy‑duty, transfer switch‑ready units to compact, safe, inverter designs suitable for protecting critical loads during outages.
