Abstract

A case battery for a personal digital assistant is provided. The case battery includes a holding portion and a charging portion. The holding portion holds the personal digital assistant detachably. The charging portion is disposed in the holding portion and configured to be electrically connected to the power input. The charging portion extends the usage time of the personal digital assistant. The charging portion includes an electrical power acceptor configured to accept electrical power from outside. The charging portion may further include a secondary battery, and the electrical power acceptor is configured to charge the secondary battery using an external electrical power source. The charging portion may include a primary battery and a receptacle configured to accept the primary battery. The case battery may further include a memory device and a computing device.
