Electrical plug adapter having socket key safety system

A system, comprising:

• an adapter comprising:
• a socket defined by a first technical standard and comprising a neutral socket, a power socket, and a ground socket;
• a plug defined by a second technical standard and comprising a neutral blade, a power blade, and a ground blade;
• at least one key extending out from a face of the socket;
• and
• an adapter housing, wherein the socket and the plug are disposed on opposing sides of the adapter housing;
• an electric vehicle (“EV”) power adapter, the EV power adapter comprising:
• a second plug compatible with the first technical standard and comprising a second neutral blade, a second power blade, and a second ground blade;
• and
• at least one complementary key socket extending inward from a face of the second plug, wherein the at least one complementary key socket is aligned with the at least one key of the adapter;
• wherein the socket of the adapter is configured to receive the second plug wherein the at least one complementary key socket is aligned with the at least one key of the adapter, wherein the at least one complementary key socket is configured to receive the at least one key so as to electrically couple the second neutral blade to the neutral socket and the neutral blade, electrically couple the second power blade to the power socket and the power blade, and electrically couple the second ground blade to the ground socket and the ground blade.
