DuroStar DS13000MX Dual Fuel
With 13,000 watts of peak power and dual-fuel capability, the DS13000MX provides flexibility for gas or propane, ensuring longer run times and broad compatibility for backup power. The CO alert feature automatically shuts down the unit if dangerous fumes are detected, adding a critical safety layer for indoor or semi-enclosed operation. It is designed for whole-home power backup or heavy-duty job sites where reliable output is essential.
DuroMax XP13000EH Dual Fuel
XP13000EH is a flagship dual-fuel generator from DuroMax, delivering ample power for whole-home backup or large work sites. It supports both gasoline and propane fuels, enabling users to adapt to fuel availability. The unit is built to withstand frequent use, with a focus on durability and reliable starting performance. It is commonly paired with transfer switches for seamless power transfer during outages.
Westinghouse 13500 Peak Watt Dual Fuel
This Westinghouse model targets higher peak output with dual-fuel capability, featuring a 500cc OHV engine and a long-run fuel range. It includes a transfer switch-ready setup, a digital hour meter, and safety protections such as CO shutdown. The design emphasizes robust performance for larger homes or remote job sites requiring substantial power during outages or off-grid moments.
Westinghouse 4000 Peak Watt Inverter
Though smaller in scale, this Westinghouse inverter offers reliable 3,300W continuous power on both gas and propane, with quiet operation and portability. It is designed for RV use, light-home essentials, and parallel capability with compatible units. Features include remote start, multiple outlets, and automatic low oil and CO shutdown protections for safer, more efficient operation in mobile applications.
Buying Guide
Power needs and fuel flexibility are the core considerations when choosing a portable generator that runs on gas or propane. Consider the following:
- Power requirements: Estimate the total wattage of essential appliances and devices to determine needed running and surge watts. For whole-home backup, prioritize higher running watts and a generous surge rating.
- Fuel versatility: Dual- and tri-fuel units offer flexibility during fuel shortages or outages. Ensure the model you choose supports your preferred fuels and has a straightforward fuel-switch mechanism.
- Starting method: Electric starts are convenient, but consider a backup recoil option or remote start for convenience in remote locations or during outages.
- Transfer switch readiness: If connecting to a home electrical panel, verify transfer switch compatibility and the required outlets (L14-30R, RV outlets, etc.).
- Run time and capacity: Larger fuel tanks provide longer operation between refuels. Review fuel gauge features and expected runtimes at different load levels.
- Safety features: CO sensors or shutdowns, automatic low-oil shutdown, and rubber outlet covers contribute to safer operation indoors or in semi-enclosed spaces.
- Durability and noise: Heavy-duty engines, cast-iron sleeves, and sound-dampening designs influence long-term reliability and user experience, especially in residential areas.
- Maintenance: Check oil monitoring, spark plug accessibility, and ease of performing routine maintenance. A digital hour meter helps track service intervals.
