Electrical outlets and sockets deliver AC power to electric equipment throughout buildings and at external sites by connecting it directly to the AC supply. Electric outlet varieties distinguish themselves based on voltage and current limits, design style, size, and connection types. World regions utilise a variety of different plug systems due to their differing requirements. Power connectors for mobile appliances emerged in the late 19th century, aiming to substitute for direct socket attachments to fixed lights sockets. Pluralism in designs arose simultaneously with improvements in electrical safety standards to address accidental injury. Over two hundred common electric outlet variants currently circulate globally; meanwhile outdated styles can still be seen within aged establishments. Global unification of technical requirements enabled several universal electric connectors across expansive territories for streamlined international trading of electronic products, and also benefited travelling customers acquiring overseas electronic items. Electrical multi-port outlets sometimes accept diverse types of plugs; adapters fashioned in-between plug systems might offer partial rather than optimal security as well as overall system functionality like the certified original socket – connection set.
