Abstract: A wireless charger for an electronic device. The charger includes a base having a base opening and an interior cavity defined by an upper shell, a lower shell and an inner sidewall extending between the upper and lower shells to define the base opening. An aperture is formed through the inner sidewall between the interior cavity and the base opening and a hinge is connected to the base within the interior cavity and extends through the aperture. The charger further includes a wireless charging assembly that is pivotably attached to the base by the hinge and moveable between a down position in which the wireless charging assembly is disposed within the base opening and an up position in which the wireless charging assembly extends outside the base. The charging assembly has a charging surface and a power transmitting unit disposed adjacent to the charging surface where the power transmitting unit is configured to wirelessly transmit power across the charging surface to a power receiving unit of a portable electronic device.
