Abstract

A charging system for portable equipment is provided which may be used in a system including an information terminal and portable equipment connected to the information terminal. The charging system includes a power supply output device provided with the information terminal and a first battery control device provided with the portable equipment. The power supply output device is capable of supplying electric power, which is supplied to the information terminal, to the portable equipment. The first battery control device receives electric power supplied from the power supply output device and performs a charging operation for a battery of the portable equipment.
