Our portable generators picks at a glance
At $999, the Westinghouse WGen9500DF is the default storm-backup pick: 9,500 running watts on gas, 8,500 on propane, remote key-fob start, and both an L14-30R transfer-switch outlet and a 50-amp 14-50R. Value leads at 92, Satisfaction hits 94, and Reliability 93 across 8,900 ratings at 4.7 stars. Quality sits at 80 because this is a conventional open-frame unit, loud and not safe for sensitive electronics without a UPS, and it weighs 210 pounds. Warranty scores 78 on 3 years. It is for homeowners who want to run most of a house through a transfer switch.
