1. A power adapter, comprising:
- a transformer for converting electrical power;
a housing configured to enclose the transformer, the housing having a plug region, a connection opening, top and bottom faces and four side faces extending between the top and bottom faces;
a power cable disposed at an exterior surface of the housing and operatively coupled to the transformer;
contact pins positioned within the connection opening and operatively coupled to the transformer;
a detachable plug having a plug body that is received by the plug region of the housing, prongs configured for insertion into slots of an electrical outlet, and a plug connector operatively coupled to the prongs, wherein when the detachable plug is received by the plug region of the housing the plug connector is operatively coupled to the contact pins, a plug top surface is coplanar with the top face, a plug bottom surface is coplanar with the bottom face and two adjacent plug side surfaces are coplanar with two side faces of the housing; and
a holding mechanism for releasably holding the plug body within the plug region, the holding mechanism including a notch formed of the plug body adapted for slidably engaging a protrusion that extends from a surface of the housing.
