Europlug
The Europlug is a flat, non-rewirable two-pole, round-pin domestic AC power plug, rated for voltages up to 250 V and currents up to 2.5 A. It is a compromise design for low-power Class II appliances that is compatible with all round-pin domestic power socket used across Europe (though not the rectangular-pin BS 1363 sockets found in the United Kingdom or the former British colonies of Cyprus, Ireland, and Malta). By the standard, Europlugs must be non-rewirable and must be supplied attached to a power cord; anything else is non-compliant.
The plug is often used on the housing of small plug-in power supplies. Though standardization excludes it, there are cable couplings for Europlugs and rewireable plugs available.
