Patent ID: 10291059

Abstract:
A charging apparatus for charging a portable electronic device includes a receiving area, two coil pairs, and coil control circuitry. The receiving area is configured to removably receive the portable electronic device and/or a case for a portable electronic device. The two coil pairs are positioned around a perimeter of the receiving area of the charging apparatus. Each coil pair includes first and second electrically conductive coils. The second electrically conductive coil is opposite the first electrically conductive coil on the perimeter of the receiving area and the ends of each electrically conductive coil including electrical leads. The coil control circuitry is electrically connected to each electrically conductive coil. The coil control circuitry is configured to selectively provide a charging current to at least one of the coil pairs to induce a magnetic field around the electrically conductive coils for inductively charging the portable electronic device.
