Abstract
A cordless telephone system in which a battery of a mobile unit can be charged with use of a cordless charger. The charger, which is provided separately from a base unit, has a chargeable battery which is larger in current capacity than the battery within the mobile unit. When the mobile unit is mounted on the charger, the battery of the mobile unit is charged with the battery of the charger. So long as the charge level of the battery within the charger is sufficiently high, the battery of the mobile unit is charged with the battery of the charger and without use of a commercial AC power source.
