Abstract: A universal charging dock for charging a mobile device includes a base portion defining an opening, a back support portion connected to the base portion, a connector housing within the opening, and a wall mount module. The base portion has grooved sidewalls adjacent a track within the opening, and the connector housing has a grooved track that locks into the track and allows lateral movement along the track. The grooved track further allows the connector housing to rotate within the opening. A male connector, for connecting to a charging port of the mobile device, extends from the connector housing and may move vertically into or out of the connector housing to adjust an extension of the male connector. The universal charging dock may also be placed on either side, to achieve portrait or landscape orientations.
