Europlug

The Europlug (CEE 7/16) is a flat, two-pole domestic AC power plug that is generally supplied moulded on the end of an appliance's flex or a power cord, designed for voltages up to 250 V and currents up to 2.5 A. It was designed such that it can safely be used in the domestic power sockets of all European countries, except for the BS 1363 system found in Britain, Cyprus, Gibraltar, Ireland and Malta.
