Abstract

A charging device capable of charging a portable telephone in the same period of time with no regard to the ON/OFF state of a power source incorporated in the telephone. When the connection of the telephone to the charging device is detected, whether or not a power source incorporated in the telephone is in an ON state is determined. A charging current to the telephone is changed depending on the ON/OFF state of the power source of the telephone.
