The Westinghouse 18000 Peak Watt Dual Fuel Generator is a powerful home backup solution that runs on either gasoline or propane, giving you flexibility during outages. It delivers 14,500 running watts on gas and slightly less on propane, which is enough to power most household essentials and some heavy-duty tools.

This generator includes a convenient electric start with a remote key fob, making it easy to get going from a distance.

It weighs 405 pounds, so while it has wheels and handles, it’s quite heavy and might not be very easy to move around frequently.

The generator offers a good variety of outlets including standard household plugs, RV connections, and USB ports, making it versatile for many devices and appliances. It also has features like automatic voltage regulation and low total harmonic distortion, which help protect sensitive electronics like phones and computers.

Due to its size and weight, this model may not be ideal for those needing a more portable option.
