Abstract: A battery with a generally cuboid body with a top face. A cylindrical terminal extending from a center of the top face, a top of the cylindrical terminal provided with electrical contacts. A left tab and a right tab provided extending from the top face proximate a left end and a right end of the top face, respectively. A peripheral portion of each of the left and the right tabs forming a retaining groove extending from the top face; and an inward facing portion of the peripheral portion of each of the left and the right tabs facing the cylindrical terminal provided with an arc radius centered upon the center of the top face. The battery interconnectable with a range of electronic devices via a range of vectors and/or mechanics.

Abstract: A foldable watch charging adapter has a watch charging housing provided with an induction charge surface. The watch charging housing is coupled to a charge end of a charge arm. A joint rotatably couples a pivot end of the charge arm to a joint end of a connector arm; and an electrical connector is provided at a connector end of the connector arm. An angular interconnection orientation of the electrical connector may be adjusted by rotating the connector arm with respect to the charge arm about the joint. Further, a connection interface adapter may be included to increase the range of connection interfaces that may be utilized.
