Home electronics wattage varies by device; DOE advises measuring or checking adapters for accurate values.
Never operate a fuel-burning generator indoors, in a garage, on a porch, or near open windows. Use a listed transfer switch or interlock installed by a qualified electrician for home wiring, and verify actual device nameplates before buying equipment.
