Pulsar G12KBN Heavy Duty Dual Fuel Generator
The Pulsar G12KBN combines 12,000 peak watts with 9,500 running watts on gasoline and 10,800 peak/8,550 running watts on LPG, delivering strong performance for storms, outages, and larger power needs. Dual fuel capability provides flexibility when gas is scarce or LPG is more readily available, helping households extend run times and manage fuel sources. It uses a 457cc, single-cylinder, 4-stroke OHV engine with an electric start and a powder-coated frame for durability. A transfer switch-ready design supports smooth integration with home electrical systems, and RV readiness adds versatility for campground or on-site uses.
Key considerations:
- Power options cover typical home backup loads and essential circuits with flexibility between fuel types.
- Dual fuel design can simplify fueling during emergencies or when gas supplies vary.
- Remote or manual starting options and frame protection improve reliability in harsh conditions.
WEN 11,000-Watt Dual Fuel Portable Generator (DF1100T)
The WEN DF1100T offers 11,000 surge watts and 8,300 running watts on gasoline, plus 9,500 surge watts and 7,500 running watts on propane. Its simple fuel-source switch makes it easy to adapt to available fuel. The unit supports 120V and 240V output, which is ideal for transfer switches and backup power setups. An electric starter with a 457cc OHV engine provides quick startup, while the wheel kit enhances portability for outdoor jobsites or camping trips. The design focuses on user-friendly operation and stable power delivery for essential home loads.
Key considerations:
- Dual voltage options simplify bridging across different appliances and circuits.
- Propane can extend run times and is often easier to store than gasoline.
- Portability features help position the generator where it’s needed most during outages.
DuroStar DS13000MX 13,000-Watt Dual Fuel
The DS13000MX delivers 13,000 watts when using gasoline and a lower yet substantial output on propane, making it a robust whole-home backup option. It features a remote electric start for convenient operation from a distance and is designed for transfer switch readiness, RV use, and emergency readiness. The dual-fuel capability supports flexible fuel management during extended outages, while the heavy-duty build targets reliability under heavy loads. The model emphasizes power resilience for larger homes or job sites.
Key considerations:
- Remote start enhances accessibility during adverse weather or in hard-to-reach locations.
- High power output supports multiple circuits and essential appliances simultaneously.
- Dual fuel reduces dependence on a single fuel supply during emergencies.
Westinghouse EFI 12,500 Dual Fuel
This Westinghouse EFI dual-fuel model provides up to 9,500 running watts on gasoline and 8,500 running watts on propane. It features an EFI (electronic fuel-injection) system that can improve throttle response and fuel efficiency. The unit includes a remote start, transfer-switch readiness, and a suite of outlets suitable for home backup or jobsite power. CO sensor integration enhances safety by monitoring carbon monoxide levels and providing automatic shutdown if needed. The generator is designed for dependable power with modern sensor technology.
Key considerations:
- EFI design can offer smoother performance and potentially better fuel economy.
- Multiple outlets and transfer-switch readiness fit diverse backup scenarios.
- CO sensor adds a critical safety layer for interior uses.
Westinghouse 12500 Watt Dual Fuel Home Backup
Designed for home backup, this Westinghouse model delivers 9,500 running watts (gas) and 12,500 peak watts, with propane delivering about 8,500 running watts and 11,200 peak watts. Features include a remote start with a key fob, a 6.6-gallon fuel tank with a fuel gauge, and multiple outlets, including transfer-switch-ready options for a seamless home power transition. Rubber outlet covers protect against the elements, while the 457cc Westinghouse OHV engine and automatic low oil shutdown contribute to safe, long-term operation during outages.
Key considerations:
- High peak power supports critical circuits during outages.
- Transfer-switch readiness enables a quick home backup connection.
- Longer run times and safety sensors improve reliability and user peace of mind.
Buying Guide: Key Purchase Considerations
Power needs and fuel flexibility
Estimate both essential and non-essential loads to determine starting and running watts. Dual-fuel capability adds flexibility for fuel availability and storage. Consider whether you need 120V, 240V, or both to support home circuitry and large appliances.
Starting method and portability
Electric start is convenient for frequent outages, while remote start or wheel kits improve placement and accessibility. If you plan to move the unit often, prioritize portability features such as wheels, handles, and weight distribution.
Safety features
Look for CO sensors, automatic shutdown, and robust frame construction. Transfer-switch readiness helps prevent back-feeding into the electrical system, reducing safety risks during outages.
Run time and tank capacity
Longer run times reduce refueling pauses during extended outages. Check fuel capacity and efficiency for both gasoline and propane modes, as this impacts how many hours you can operate before refueling is needed.
Outlets and compatibility
Ensure the generator offers a range of outlets (GFCI, twist-lock, RV outlets) and that the configuration works with your home’s circuits and any transfer-switch equipment you use.
