Westinghouse 12500 Watt Dual Fuel Generator
Best for: Homeowners needing robust power during outages plus transfer-switch readiness. This model delivers 9500 running watts on gasoline and 8500 running watts on propane, with a peak of 12500 watts on gasoline and 11200 on propane. It includes remote start via key fob, electric and recoil start options, and a large 6.6-gallon tank with a fuel gauge for extended run time. Safety and visibility are enhanced by a digital hour meter and a VFT display showing voltage, frequency, and lifetime hours. Ideal for larger homes or multiple circuits running simultaneously.
Why selected: It combines high power with dual-fuel flexibility and a transfer-switch-ready design, making it easier to integrate with home electrical panels. A limitation to consider is its size and weight, which reduces portability for casual use.
Caution: Heavy-duty engine requires regular maintenance; ensure proper oil levels and tire/stand stability if moving the unit between locations.
DuroMax XP13000EH Dual Fuel Generator
Best for: Homes needing strong emergency power with fuel flexibility. The XP13000EH provides up to 13,000 watts of power and supports both gasoline and propane. It is designed for whole-home backup and is transfer-switch ready, making it suitable for storm preparedness and remote job sites. Its dual-fuel approach helps you adapt to fuel availability.
Why selected: This model emphasizes high output with dual-fuel convenience, a common requirement during outages. A potential limitation is that dual-fuel operation may require more routine maintenance and parts inventory compared to single-fuel units.
Westinghouse 2550 Peak Inverter Generator
Best for: Individuals needing quiet, efficient standby power for essential loads. This inverter model runs on gas or propane, weighs about 42.4 pounds, and features an RV-ready TT-30R outlet along with two 120V outlets and two USB ports. It excels in lower-noise environments and fuel efficiency with economy mode, offering up to 12 hours on a small tank for light loads.
Why selected: Its compact design and quiet operation make it a practical choice for apartment backups or camping setups. However, its peak power is modest compared with larger, non-inverter units, limiting it to essential circuits when needed.
Caution: Best suited for essential loads; avoid heavy simultaneous power draws on high-watt appliances.
DuroStar DS13000MX Dual Fuel Generator
Best for: Homeowners seeking heavy-duty, remote-start power with substantial wattage. The DS13000MX provides 13,000 watts and supports dual-fuel operation. It is designed for whole-home backup and is transfer-switch ready, with a CO alert system helping protect occupants from dangerous fumes.
Why selected: The combination of high wattage, dual-fuel capability, and safety features makes it a strong all-around choice for generators intended to handle multiple loads during outages. A limitation might be the size and ongoing fuel management for heavy use.
Generac 12,500 Starting Watt Tri-Fuel
Best for: Families needing maximum fuel flexibility and an easy start during emergencies. This Generac unit runs on gasoline, propane, or natural gas with a simple fuel selector dial. It provides 9,500 running watts and 12,500 starting watts, and includes COsense carbon monoxide detection for safety. Electric start with a rechargeable battery simplifies activation in cold weather.
Why selected: Tri-fuel capability covers the widest range of fuel types, reducing the risk of being without power due to fuel scarcity. A note: ensure compatible transfer switch and proper venting for safe operation indoors or outdoors.
Buying Guide: Key Purchase Considerations
- Fuel flexibility: If you want true versatility, prioritize dual- or tri-fuel models to cope with fuel availability during outages.
- Power needs: Assess running watts vs. starting watts and plan for your essential circuits or whole-home load profile.
- Safety features: Look for CO sensors, automatic shutdowns for low oil, and rubberized outlet covers for weather protection.
- Starting method: Electric start is convenient, especially in cold seasons; recoil start provides a backup option.
- Run time and tank size: Longer runtimes are beneficial for multi-day outages; check tank capacity and fuel efficiency features like economy mode.
- Transfer switch compatibility: Ensure the unit is transfer switch ready if you plan to connect to a home panel.
- Portability vs. power: Heavier units deliver more power; lighter units excel in portability for trailers or campsites.
Frequently Asked Questions
- What does “dual fuel” mean for a generator?
It means the unit can run on two different fuels, typically gasoline and propane, providing flexibility during outages. - Is a CO sensor important on a generator?
Yes, a CO sensor helps automatically shut down the unit if dangerous carbon monoxide levels are detected, increasing safety. - What is a transfer switch and why do I need one?
A transfer switch directs power from the generator to your home’s circuits, enabling safe and convenient connection during outages. - How do I choose between a portable inverter and a standard generator?
Inverters are quieter and provide clean power for sensitive electronics, but generally have lower peak wattage than standard generators. - Can I run a whole house on a portable generator?
Some models are transfer-switch ready and can power essential circuits or high-demand loads, but verify your home’s load requirements and panel compatibility. - Do these generators come with fuel and oil included?
