The Westinghouse 12500 Watt Dual Fuel Generator is a solid choice for those looking for a reliable power source for home backup or outdoor activities. With a powerful output of 9500 running watts and 12500 peak watts when using gasoline, and slightly less on propane, it offers plenty of power for essential appliances. One of its standout features is the remote start with a key fob, which adds convenience, especially during emergencies.

Portability is another strength, as this unit is designed to be easily moved, weighing 210 pounds and equipped with a good fuel capacity of 6.6 gallons that provides up to 12 hours of runtime. The noise level is reasonable for a generator of this size, making it suitable for use in residential areas, although it’s still important to consider the noise during operation.

The generator comes with multiple outlets, including GFCI receptacles and RV-ready options, ensuring versatile connectivity for various devices. It also features helpful safety mechanisms like automatic low oil shutdown and rubber covers for the outlets. The 210-pound weight may make it challenging for some users to transport without assistance. Additionally, while it is designed to run on both gasoline and propane, users may need to familiarize themselves with switching between fuel types, which could be a slight learning curve for some. This generator is ideal for homeowners needing backup power or outdoor enthusiasts looking for a dependable energy source, but users should weigh the portability and operational aspects against their personal needs.

The Westinghouse 5000 Peak Watt Super Quiet Dual Fuel Portable Inverter Generator is a solid choice for those needing a reliable power source for both home and travel.

Its dual fuel capability allows it to run on either gasoline or propane, providing flexibility in fuel choice and availability. The generator features a 3.4-gallon tank and can run up to 18 hours on gasoline, making it highly efficient for extended use.

The noise level is impressively low at 52 dBA, which is quieter than many comparable generators, making it suitable for residential areas or campsites where noise reduction is important.

The starting mechanism is user-friendly with remote electric start, electric start, and recoil start options.

The generator includes multiple outlets (a 120V duplex household outlet, an RV-ready 30 Amp outlet, and two USB outlets), catering to various connectivity needs. The LED data center is a useful feature, providing real-time information on fuel level, power output, remaining run time, voltage, and lifetime hours. Additionally, the generator is backed by a 3-year limited warranty and comes with several included components like an oil bottle, oil funnel, spark plug wrench, remote, propane regulator/hose, and battery float charger. Some drawbacks include the weight, which might make it less portable for some users, and the relatively high price compared to non-inverter generators. However, its dual fuel capability, efficiency, quiet operation, and extensive features make it a valuable investment for both commercial and residential use.

The WEN Quiet and Lightweight 3600-Watt Dual Fuel RV-Ready Portable Inverter Generator (DF360iX) offers a versatile power solution by running on both gasoline and propane, producing 3600 surge watts and 2900 rated watts on gasoline, and slightly lower on propane. Its dual-fuel capability is a significant strength, providing flexibility in fuel choice.

The 5-hour runtime on a 1.5-gallon tank may be short for extended use, requiring frequent refueling during prolonged power outages. However, this is somewhat balanced by the fuel efficiency from the inverter technology. The starting mechanism is spark ignition, which is standard but may not be as convenient as electric start options available on some other models. Backed by a three-year warranty, the WEN generator appears to be a solid choice for those needing a reliable and versatile power source for residential, camping, and RV use, though users should be prepared for relatively frequent refueling.
