Westinghouse 14500 Peak Watt Tri-Fuel
The Westinghouse 14500 Peak Watt Tri-Fuel unit combines high output with flexible fuel options for emergencies. Gasoline mode delivers up to 11,500 running watts, while propane and natural gas modes provide around 10,500 and 9,500 running watts, respectively. A heavy-duty 550cc four-stroke OHV engine powers extended runtimes, especially with a full 9.5-gallon gas tank. Its capability to run on propane at the strength of a typical household tank makes it a practical standby for longer outages. The unit is designed for remote electric start and transfer switch readiness, aligning with home backup needs. Safety features include automatic low-oil shutdown and a durable build for rugged environments.
Westinghouse 13500 Peak Watt Tri-Fuel
The Westinghouse 13500 Peak Watt Tri-Fuel model provides 10,500 running watts on gasoline and up to 12,500 peak watts on propane, with 10,000 peak and 8,500 running watts on natural gas. It includes a remote start with a key fob and supports both electric and recoil starting. A 9.5-gallon fuel tank with a fuel gauge supports long runtimes, complemented by multiple outlets: two standard 5–20R 20A outlets, a 30A transfer switch, and a 50A RV-ready outlet. It features CO shutdown, automatic low-oil protection, and a digital hour meter for maintenance planning.
WEN 14,500-Watt Tri-Fuel (TF1450X)
The WEN TF1450X Tri-Fuel generator lets you switch between gasoline, propane, and natural gas with a simple dial, providing up to 11,500 running watts on gasoline, 10,300 on propane, and 8,750 on natural gas. It operates in both 120V and 240V configurations, supporting common transfer switch setups and emergency back-ups for home appliances. The WEN system also includes a CO watchdog sensor to automatically shut down if dangerous carbon monoxide levels are detected, enhancing safety during operation in enclosed spaces or garages. The design emphasizes practicality, with accessible outlets and a user-friendly interface.
Generac 12,500 Starting Watt Tri-Fuel
The Generac GP9500/12,500Starting Watt Tri-Fuel unit prioritizes robust protective features and easy operation. It includes an electric start with a battery for quick, reliable startup and supports extended runtime with a sizable fuel capacity. The unit is designed for use as a home backup, jobsite, or RV power source, with a durable enclosure to tolerate harsh conditions. The package emphasizes safety and reliability, including simple access to outlets and a practical arrangement of switching options for quick setup during outages. The generator is designed to deliver dependable power when it matters most, while meeting 50-state compliance expectations.
Westinghouse 8200 Peak Watt Tri-Fuel
The Westinghouse iGen8200TFc combines inverter benefits with tri-fuel flexibility and home backup capabilities. Gasoline mode offers 8,200 peak watts, propane provides around 7,380 peak watts, and natural gas delivers about 6,560 peak watts. Its inverter technology reduces engine speed as power demand drops, delivering quieter operation and greater fuel efficiency. Convenience features include a 50A transfer switch-ready outlet for whole-house needs, plus RV-ready and standard outlets. This model emphasizes clean power suitable for electronics thanks to low total harmonic distortion (THD) and a CO sensor for added safety.
Buying Guide: Key Purchase Considerations And Comparisons
Fuel flexibility is the core advantage of tri-fuel generators. When evaluating options, consider running watts for essential appliances (refrigerators, sump pumps, lights) and peak watts for startup surges. A larger tank extends runtimes on gasoline, while propane and natural gas baseloads reduce refueling frequency during outages.
Important features to compare include remote electric start versus manual start, transfer switch readiness, and the availability of RV-ready outlets for campers or work sites. Safety features such as CO shutdown sensors, oil alerts, and robust enclosure protection protect users in both garages and outdoor environments. Inverter-based tri-fuel models deliver cleaner power and lower noise, making them preferable for electronics and residential use, though they may trade some outright peak power for smoother operation.
Consider runtime estimates at a given load. Some models advertise long hours at 50% load, which translates well into everyday outage scenarios where power needs are moderate but constant. The type of engine (OHV, cast iron sleeve) influences durability, maintenance intervals, and fuel efficiency. If you plan to run an air conditioner or high-draw devices, verify that the unit’s peak watts meet those loads with a comfortable margin.
Portability and durability matter for residential use and job sites. Wheels, handles, and frame construction affect transport and storage. Finally, ensure the model you choose has a comprehensive warranty and access to spare parts or service in your region for long-term reliability.
