Abstract

The invention includes a peripheral charging system for a computer. The peripheral charging system comprises a retention mechanism configured to retain a peripheral having a battery, the retention mechanism comprising a charging mechanism, and a system battery electrically connected to the charging mechanism. When the peripheral is retained by the retention mechanism, the peripheral contacts the charging mechanism of the retention mechanism to charge the peripheral battery. The invention also comprises a method for charging a peripheral for a mobile computing device. The method comprises retaining the peripheral in a retention mechanism of the mobile computing device, and charging a battery of the peripheral device from a battery of the mobile computing device. The retention mechanism of the mobile computing device includes a charging mechanism configured to supply charge to a charging mechanism of the peripheral.
