1. A power adapter, comprising:
- a rectangular body having top and bottom faces and four side faces extending between the top and bottom faces, the top and bottom faces being larger than the side faces, the four side faces including a first side face extending between second and third side faces, the third side face extending between a fourth side face and the first side face, the rectangular body having a transformer for converting electrical power housed therein;
a plug body having spaced-apart prongs capable of extending in a direction perpendicular to the second or the fourth side face and adapted to mate with slots of an electrical outlet, the prongs electrically coupled to the transformer, the plug body removably attached to the rectangular body, the plug body having an exterior surface that extends between the second and fourth side faces of the rectangular body when the plug body is attached to the rectangular body; and
an electrical connection on one of the four side faces, the electrical connection coupled to the transformer.

8. 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, the top and bottom faces being larger than the side faces, the housing having rounded edges and rounded corners where the top, bottom and side faces meet; a power cable disposed at an exterior surface of the housing; 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, the plug region positioned on the housing where the top, bottom and two sides faces meet, the plug connector extending from the plug body and including electrical contacts operatively coupled to the prongs, the plug connector being insertable into the connection opening disposed in the housing so as to electrically engage the contact pins and electrical contacts thereby making an operable power connection between the transformer and the prongs; 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. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A power adapter, comprising:
-
electrical components configured to convert AC power received by the power adapter into external DC power; a housing configured to enclose the electrical components, the housing having a plug region, a connection opening, top and bottom faces and four side faces extending between the top and bottom faces, the top and bottom faces being larger than the side faces, the four side faces including a first side face extending between second and third side faces, the third side face extending between a fourth side face and the first side face; a power cable disposed at a first side of the side faces of the housing; contact pins positioned within the connection opening and operatively coupled to the electrical components; 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, the plug connector extending from the plug body and including electrical contacts operatively coupled to the prongs, the plug connector being insertable into the connection opening disposed in the housing so as to electrically engage the contact pins and electrical contacts, thereby making an operable power connection between the electrical components and the prongs; and a holding mechanism for releasably holding the plug body within the plug region, wherein the detachable plug includes an exterior surface that extends between the second and fourth side faces of the rectangular body when the plug body is attached to the housing. - View Dependent Claims (16, 17, 18, 19, 20)
