Westinghouse 12500 Watt Dual Fuel Backup Generator
The Westinghouse 12500 Watt Dual Fuel Generator provides substantial power with dual-fuel flexibility and a convenient remote start. Gasoline mode delivers 9500 running watts and 12500 peak watts, while propane mode offers 8500 running watts and 11200 peak watts. The unit ships with a key fob for remote electric start and includes both recoil and electric starting options for reliability during storms or outages. The 6.6-gallon fuel tank supports long runs, and a digital hour meter plus a VFT display keep you informed of voltage, frequency, and hours in use. A heavy-duty 457cc Westinghouse engine powers the unit and supports safe operation with automatic low-oil shutdown. This model also features multiple outlets, including a transfer switch-ready 120V L14-30R and an RV-friendly 50A receptacle, all protected by rubber outlet covers for weather resistance.
Use cases include essential circuits in larger homes, RVs, and job sites where dependable power is critical. If you expect frequent outages or plan to connect to a transfer switch, this generator’s capacity and outlets make it a versatile centerpiece for home backup systems. Consider pairing with a compatible automatic transfer switch for a seamless transition from utility power to generator power without manual intervention.
WEN 4,750-Watt Dual Fuel Portable Generator
The WEN DF475T offers a practical balance of power, fuel flexibility, and mobility. It switches between gasoline and propane with a simple dial, providing 4750 surge watts and 3800 running watts on gasoline, and 4350 surge watts with 3500 running watts on propane. The generator outputs 120V and 240V, which makes it compatible with basic transfer switches and emergency setups. While not a heavy-duty home backup on its own, the DF475T suits smaller households, cabins, or tools-and-lighting needs during outages. An electric start streamlines operation, and the unit remains portable enough for occasional use around a homestead or campsite.
DuroStar DS13000MX 13,000-Watt Dual Fuel
The DuroStar DS13000MX is designed for whole-home power backup with dual-fuel capability and a robust 500cc engine. It delivers 13,000 watts of power on gasoline with strong running watts and offers propane options for longer duration or fuel supply flexibility during extended outages. The model emphasizes safety with features such as CO monitoring to shut down in dangerous conditions, protecting occupants from harmful fumes. The unit is built for transfer-switch readiness and provides multiple outlets for essential circuits, RV connections, and other loads. Remote electric start enhances convenience when you’re away from the unit, and the generous fuel tank capacity supports longer operation times between refuels.
WEN 6800-Watt Dual Fuel Inverter Generator
The WEN DF680iX combines dual-fuel capability with inverter technology and a bonded-neutral 240V configuration, supporting reliable Level 2 charging for battery-electric and hybrid vehicles, in addition to standard backup power. It delivers 6800 surge watts and 5100 running watts on gasoline, and 6000 surge watts with 4500 running watts on propane. The CO Watchdog sensor adds an essential safety layer by automatically shutting down the unit in the presence of dangerous carbon monoxide levels. This model appeals to homeowners seeking EV support during outages or those who need clean, stable power for sensitive electronics while on the go.
Westinghouse 6600 Watt Backup Generator
The Westinghouse 6600 Watt model emphasizes a balance of power and convenience with an electric start remote, CO sensor, and transfer-switch-ready design. A 4.7-gallon tank supports lengthy run times, and the 120/240V power selector offers flexibility for home distribution. The unit includes multiple receptacles, including a 5–20R 120V duplex outlet and an RV-ready TT-30R, for straightforward connection to essential circuits or recreational vehicles. The included accessories, such as a wheel kit, oil, and tool kit, help with quick setup and mobility after delivery. The CO sensor helps mitigate risk in occupied spaces and aligns with safety-focused operation during outages.
WEN 5,600-Watt Dual Fuel Portable Generator
The WEN DF5600X focuses on practical power with dual-fuel operation and a CO shutdown sensor for safety. It delivers 5600 surge watts and 4500 rated watts on gasoline, or 5000 surge watts and 4050 rated watts on propane. An electric start ensures quick startup during outages, while its transfer-switch readiness makes it a candidate for more integrated home backup systems. This model suits mid-sized homes, workshops, or cabins where reliable power and safety features are priorities, without the extreme output found in larger units.
Buying Guide: Key Purchase Considerations for Auto Start Generators
- Power needs and load capacity: Compare running watts (continuous) and surge watts (peak). Larger homes may require 10,000+ running watts, while smaller setups can do with 4,000–6,000 running watts. Consider essential circuits and future needs.
- Fuel type and availability: Dual-fuel models increase flexibility in fuel shortages. Propane can be easier to store long-term, while gasoline provides maximum power. Natural gas or propane hookups may influence installation choices.
- Automatic start and transfer switch: Remote or automatic start simplifies operation during outages. Ensure compatibility with a transfer switch or a professionally installed interlock kit to prevent backfeeding and ensure safe switching.
- Safety features: CO detectors, low-oil shutdown, and rubber outlet covers reduce risk and extend equipment life. Look for overload protection, surge handling, and proper grounding.
- Run time and tank capacity: Larger tanks support longer outages, but heavier units may limit portability. Balance endurance with weight, noise, and space requirements in your setup.
- Outlets and electrical configuration: Ensure sufficient outlets for essential loads and consider 120V/240V capabilities for more advanced home protection, RV connections, and EV charging readiness where applicable.
- Noise and footprint: Generators vary widely in noise levels. If you plan to install near living spaces, choose models with lower decibels or place them in compliant outdoor enclosures with ventilation.
- Maintenance and warranties: Check oil changes, filter replacements, and scheduled service intervals. Longer warranties and robust customer support add long-term value for homes that rely on backup power.
- Portability vs. permanent install: Stationary transfer-switch-ready units suit permanent backup power, while portable models work for apartments, cottages, or on-demand use with temporary setups.
- Cost and availability: While high-output, multi-fuel units command higher upfront costs, they offer greater resilience. Consider total cost of ownership, including fuel efficiency and maintenance.
