Abstract: A device for charging a mobile phone, comprising: a body having a length dimension, a width dimension and a thickness dimension, with the thickness dimension being substantially smaller than the length dimension and the width dimension; a power plug integrated in the body; and a charging and mounting support integrated on a front surface of the body, detachably and mechanically mounting and electronically connecting a back interface integrated on a back surface of a mobile phone; wherein in order to charge the mobile phone, a power connector of the charging and mounting support is connected mechanically and electronically to a power connector of the back interface; and wherein the back interface is rotationally movable and rotationally locking when mounted on the charging and mounting support.

Abstract: A connector including a first connector side having a first rotatable connector mechanism and a second connector side having a second rotatable connector mechanism, the first rotatable connector mechanism and the second rotatable connector mechanism being configured to engage one another when the first connector side and the second connector side abut one another at a first angular orientation, the first rotatable connector mechanism and the second rotatable connector mechanism being configured to disengage from one another when the first connector side and the second connector side are rotated away from the first angular orientation in at least a first direction.
