two-prong plug
Polarized outlet interface
A two-prong plug is an electrical plug with two flat metal blades that insert into a wall outlet.
Unlike three-prong plugs, it lacks a grounding pin, making it suitable for low-power devices like lamps and phone chargers but not for appliances that require grounding for safety: The old radio has a two-prong plug.
