Westinghouse 12500 Peak Dual Fuel Backup Generator
This Westinghouse model delivers 9500 running watts and 12500 peak watts when fueled by gasoline, and 8500 running watts with 11200 peak watts on propane. It features a remote start with a key fob and both electric and recoil start options for flexibility. A 6.6‑gallon tank supports up to 12 hours of runtime, depending on load, and the unit includes essential outlets with rubber safety covers. For systems integration, it offers a transfer switch ready configuration and a 457cc Westinghouse OHV engine with a cast iron sleeve for durability, plus CO shutdown protection and a digital hour meter.
DuroMax XP13000HX Dual Fuel Portable Generator
The XP13000HX provides a robust 13,000 watts of peak power, designed to back up an entire home during outages. It supports both gasoline and propane and includes a CO alert system for enhanced indoor safety. The generator is built around a 500cc OHV DuroMax engine with all copper windings to improve longevity. Users benefit from a transfer switch readiness for easy connection to home circuits, a feature widely favored for whole‑house continuity during emergencies. Propane’s clean burn and long shelf life offer practical fuel options when gasoline isn’t readily available.
Westinghouse 12500 Watt Dual Fuel Backup Generator
This unit matches the performance range of Westinghouse dual fuel models with 9500 running watts on gasoline and 8500 running watts on propane, plus 12500 peak watts on gasoline and 11200 peak watts on propane. It includes a remote start with a key fob, electric and recoil start options, and up to 12 hours of runtime on a full tank. With two GFCI outlets and a transfer switch ready configuration, it is designed for safe home backup and RV-ready compatibility, aided by a heavy duty 457cc Westinghouse engine, a CO shutdown, digital hour meter, and a VFT display for real‑time voltage, frequency, and hours.
WEN DF475T Dual Fuel Portable Generator
The WEN DF475T offers 4,750 surge watts and 3,800 running watts on gasoline, with propane options around 4,350 surge and 3,500 running watts. The dual fuel design makes it suitable for smaller homes or light loads while still offering 120/240V versatility for transfer switches and emergency backup. A wheel kit improves portability, and the 224cc engine provides reliable performance. This model emphasizes balance between cost, portability, and practical power for mid-sized outages, with flexible fueling and a compact footprint for easier storage.
Westinghouse 12500 Peak Watt Tri-Fuel Generator
The tri-fuel option adds natural gas compatibility to the common gasoline and propane mix, offering 12500 peak watts and 9500 running watts on gasoline, with 11200 peak watts and 8500 running watts on propane, plus 7500 running watts on natural gas. It includes remote electric start, transfer switch readiness, and up to 12 hours of runtime on a 6.6-gallon tank with a fuel gauge. Built on the same durable Westinghouse 457cc engine, it features CO shutdown, a digital hour meter, and multiple safety outlets with rubber covers for household use, RV readiness, and higher‑amperage needs.
Buying Guide: Key Considerations For Choosing A Dual Fuel Generator
- Power output needs: Match running watts (continuous load) and peak watts (surge) to your essential circuits and appliances. For whole-home backup, look for 9,000–13,000 running watts and 12,000–15,000 peak watts.
- Fuel flexibility: Dual fuel (gasoline and propane) or triple fuel (gasoline, propane, natural gas) expands fuel availability, with natural gas offering constant supply but lower propane/gasoline flexibility depending on pressure and line conditions.
- Starting method: Remote electric start with key fob is convenient for frequent outages; recoil or manual start remains reliable if electronics fail. Ensure compatibility with transfer switches to hard-wire essential circuits safely.
- Safety features: Look for CO shutoff sensors, low-oil shutdown, automatic voltage/frequency regulation, and weather‑resistant outlets with rubber covers. A digital hour meter helps schedule maintenance.
- Engine reliability and maintenance: A proven, durable engine (e.g., OHV designs with cast iron sleeves) reduces long-term wear. Consider units with copper windings and robust construction for longevity.
- Runtime and fuel capacity: Larger tanks yield longer runtimes under baseline loads. Plan for outage duration and typical household energy usage to estimate daily fuel needs.
- Outlets and transfer readiness: Ensure the generator offers multiple 120V outlets for common loads, plus a 240V or 120/240V RV-ready outlet and a transfer switch compatibility for seamless home integration.
- Portability vs. power: Heavy‑duty units deliver higher power but require more storage space and handling equipment. For frequent transport, consider models with wheels and ergonomic handles.
- Noise and comfort: Some models are engineered for quieter operation, which is important for residential settings, especially in close neighborhoods.
- Warranty and service: Check warranty terms and local service options. Access to authorized repair centers reduces downtime after outages.
