Best Mid-Size Portable Generators Ranked

14 portable generators from 5,000 to 8,999 running watts.

Last updated: October 28, 2026

The mid-size class is the usual home-backup generator: through a transfer switch or inlet box it runs a fridge, a freezer, a gas furnace, a well pump, lights and a few outlets at once. Look for an L14-30 outlet, which feeds both legs of the panel at 240 V, and electric start, since a pull cord on a 400 cc engine is hard work in the cold.
