Westinghouse 12500 Watt Dual Fuel Generator
Best for large homes and RV setups that need strong, flexible power. This unit runs 9500 watts on gasoline and 8500 watts on propane, with a 12500-peak watt capacity. It includes a remote start with a key fob, transfer switch readiness, and a 6.6-gallon tank for up to 12 hours of operation. The 50A RV receptacle and 30A transfer switch outlet support major load management, while the LD engine delivers durability. Best for homeowners who want both gasoline and propane options and a ready-to-use transfer switch connection.
Caution: The unit is heavy and may require professional installation for full transfer switch integration. It also relies on a larger fuel tank to achieve maximum runtime.
Westinghouse 13500 Peak Watt Dual Fuel Generator
Best for heavy loads where peak capacity matters. It delivers 10500 running watts on gasoline and 12500 peak watts, or 9500 running watts on propane with 12500 peak watts. Features a remote start, 19 hours of run time on a 9.5-gallon tank, and a 50A RV outlet plus a 30A transfer switch. This model suits larger homes or extended RV stays where sustained high power is required. Choose this if you anticipate frequent high-demand outages and need extended runtime.
Limitation: CO safety and carbon monoxide shutdown are included, but ensure proper outdoor placement and ventilation to comply with local codes and safe operation guidelines.
Westinghouse 14500 Peak Watt Tri-Fuel Generator
Best for demanding power needs across multiple fuels. This tri-fuel model delivers 11,500 running watts (gas), 10,500 running watts (propane), and 9,500 running watts (natural gas) with a 14,500 peak watt capacity. It uses a 9.5-gallon tank for up to 19 hours of runtime and offers 50A RV and 30A transfer switch outlets. Ideal for large homes or remote job sites where fuel flexibility and high load support are essential. The CO shutdown and durable engine add safe, long-term operation.
Limitation: Tri-fuel flexibility means additional parts and maintenance considerations; ensure fuel supply planning for each fuel type you intend to use.
DuroStar DS13000MX 13,000-Watt Dual Fuel
Best for dependable home backup with strong dual-fuel performance. It delivers 13,000 watts, with dual-fuel operation for gasoline or propane, and a CO alert adds safety. It is transfer switch ready, supports RV- and home-based loads, and targets customers who need a powerful, flexible backup solution with straightforward operation. The built-in safety features help when running on propane for longer durations.
Caution: The unit may require a larger footprint and careful placement to ensure adequate ventilation and safe exhaust clearance in typical residential setups.
AIVOLT 7500 Watt Dual Fuel Generator
Best for RVs and compact homes needing 50A readiness with strong dual-fuel flexibility. The AIVOLT unit outputs 6300 watts on gasoline or 5800 watts on propane, with a 50A NEMA 14-50R outlet and 50A RV capability. A CO Watch-Guard safety feature adds carbon monoxide protection, while multiple outlets ensure versatile connectivity. This model is well-suited for RV trips, small homes, or workshops requiring reliable 120/240V power with a safety focus.
Caution: While compact, it offers less peak power than larger units; avoid running power-hungry appliances simultaneously if you are near its upper limit.
Buying Guide: Key Purchase Considerations
What fuel type best fits your needs?
Gasoline is widely available and provides strong, immediate power. Propane offers longer run times with cleaner emissions, while natural gas (where supported) can simplify fueling if connected to a home line. Dual- and tri-fuel models give you important flexibility during outages or storms.
How important is peak versus running watts?
Running watts indicate continuous power, while peak watts show the maximum surge you can handle for starting motors. For whole-home backup, target higher running watts with a robust peak margin to accommodate air conditioners, pumps, and furnaces starting up together.
What outlets and transfer switch readiness do you need?
Look for 50A RV receptacles for large appliances or RVs, plus 30A or 50A transfer switch-ready configurations. Ensure the generator matches or exceeds your intended load and that your transfer switch is compatible with the model’s outlets.
Safety features you should not overlook
CO sensors or CO shutdown, overload protection, and proper enclosure ventilation are essential. Rubber outlet covers protect against moisture, and low-oil shutdown helps prevent engine damage in power outages.
Run time and tank size considerations
Longer runtimes are usually tied to larger fuel tanks. If outages are frequent, prioritize engines with bigger tanks and fuel gauges so you can plan refueling without guesswork.
Space, portability, and installation needs
Consider how much space you have for storage and whether the unit will stay outdoors. Heavier models may require a dolly or permanent mounting near your service panel, with professional installation for transfer-switch connections.

Frequently asked questions
- What does 50A RV-ready mean on a generator?
It indicates there is a 50-amp outlet suitable for RV power connections, allowing heavy-load appliances to run without overloading standard outlets. - Is a dual-fuel generator worth it for emergencies?
Yes, it provides fuel flexibility, ensuring you can refuel with whichever option is available during an outage. - Do I need a transfer switch with a portable generator?
For safety and code compliance, a transfer switch is recommended to isolate your home from the grid and prevent backfeeding. - What maintenance should I perform during non-use periods?
Follow the manufacturer’s maintenance schedule: check oil, fuel stabilization, air filter, and battery charge for electric start systems. - Can these generators power a whole house?
Many can, but confirm wattage requirements of your home circuits and have a licensed electrician assess transfer-switch needs for full-house backup.
