Westinghouse 12500 Watt Dual Fuel Generator
Features include 9500 running watts and 12500 peak watts on gasoline, and 8500 running watts with 11200 peak on propane. It offers remote start via key fob, electric and recoil start, and run times up to 12 hours on a 6.6-gallon tank. It has a 30A transfer switch-ready outlet and an RV-ready 50A outlet, plus a 20A standard household outlet, all with safety rubber outlet covers. The engine is a heavy-duty 457cc Westinghouse 4-stroke OHV with automatic low-oil shutdown and a digital hour meter. The VFT display shows voltage, frequency, and lifetime hours in real time. Best for homeowners who want backup power with remote start and multiple receptacles, including transfer switch readiness. Caution: Propane power is lower than gasoline; choose fuel based on run-time needs and fuel availability.
WEN 11,000-Watt Dual Fuel + Wheel Kit
This unit supports 11,000 surge watts and 8,300 running watts on gasoline, and 9,500 surge and 7,500 running watts on propane. It easily switches 120V to 240V, making it compatible with transfer switches and emergency setups. The electric start powers a 457cc 4-stroke OHV engine. Best for budget-minded buyers who need a reliable dual-fuel option with easier voltage selection. Better for simpler emergency use rather than long-duration power at full gasoline output. Limitation: Gasoline output is higher than propane, so plan fuel strategy accordingly.
DuroStar DS13000MX 13,000-Watt Dual Fuel
Offers 13,000 watts of power on gasoline and flexible propane operation. It emphasizes dual-fuel capability for fuel availability, and includes a remote electric start for easier use. It is transfer switch ready and designed for whole-home power backup, including RV and emergency scenarios. Best for users needing maximum output and fuel flexibility. Safety note: Verify proper ventilation when running any generator to avoid buildup of fumes indoors or in enclosed spaces.
WEN 4,750-Watt Dual Fuel Portable
Dual fuel performance at 4,750 surge watts and 3,800 running watts (gasoline); 4,350 surge and 3,500 running watts (propane). Provides 120V to 240V output and includes a wheel kit with electric start. Best for smaller spaces or occasional emergencies where compact size matters. Choose this if you need a light, portable option and plan to run essential circuits rather than full household power. Limitation: Lower total output than larger models, suitable for targeted appliances or essential loads only.
WEN 14,500-Watt Tri-Fuel Generator
Capable of 14,500 surge watts and 11,500 running watts on gasoline, 12,500 surge and 10,300 running watts on propane, and 10,500 surge and 8,750 running watts on natural gas. It runs at 120V and 240V, making it highly versatile for transfer switches and various backup needs. It includes a CO watchdog sensor to automatically shut down on dangerous carbon monoxide levels. Best for users who require the highest flexibility across multiple fuel sources and total power, including natural gas as a utility-backed option. Caution: Tri-fuel operation depends on available fuel lines and connections; check compatibility with your installation area.
Buying Guide: Key Purchase Considerations
- Power needs: Match running and surge watts to the essential loads you plan to run. Higher surge watts help handle motor starts and larger appliances.
- Fuel flexibility: Dual- or tri-fuel units provide fuel options during outages; consider local fuel availability and storage safety.
- Transfer-switch readiness: If you want whole-home backup, choose models with transfer switch-ready outlets and sufficient amperage for your panel.
- Starting method: Remote/electric start offers convenience; recoil start is a reliable backup in case the battery fails.
- Safety features: CO watchdog or automatic shutoffs add protection in enclosed or poorly ventilated spaces.
- Portability vs. capacity: Larger wattage often means heavier units; assess whether you need wheeled portability or stationary, high-output power.
- Maintenance indicators: Digital hour meters and low-oil shutdown help track service needs and prevent damage.
FAQ
- What is the difference between running watts and surge watts?
Running watts measure continuous power; surge watts cover brief motor-start surges. - Do I need a transfer switch for home backup?
A transfer switch safely isolates your home from the grid during outages and is often recommended for high-wattage generators. - What fuels are easiest to source?
Gasoline is common, propane stores longer but may offer less power; tri- or dual-fuel units provide flexibility. - Is CO safety important?
Yes. A CO watchdog automatically shuts down the generator if dangerous carbon monoxide levels are detected. - Can I use a generator indoors?
No. Generators should operate outdoors in a well-ventilated area to prevent carbon monoxide buildup. - Which model is best for long outages?
Dual- or tri-fuel units with larger tanks and longer run times are typically better for extended outages.
