Best Generator Cover (2026): 5 Covers Compared

The GUYISS cover is made for running: all four sides roll up and fasten with buckle straps, so it stays on during operation while letting air through. Keep the exhaust side rolled up when running, and open just the exhaust and air intake sides while the other sides stay down to shield plugs from rain. The top opens for refueling without removing the cover, and the silver-plated inner lining reflects radiant heat away from the generator. It measures 32 x 24 x 24 inches and fits most 5000-13000W generators. A tie-down rope, Velcro corner fasteners, adjustable buckle straps and a bottom drawstring hold it in strong winds. It weighs 2.0 pounds.

Who it's for: owners who run the generator in rain and want the cover on while it works. Who should skip it: anyone whose generator is outside the 5000-13000W range, or who wants a stated warranty term.
