PURPOSE:To provide a plurality of cordless equipments in common use for a charger. CONSTITUTION:An electric double layer capacitor with charge voltage made in common as a power supply is provided in a plurality of cordless equipment 1. A charging DC power supply 9 and a charger 2, provided with a charging capacitor 11 between this DC power supply 9 and outputting contacts 10, are prepared. The charging capacitor 11 is left as charged with this charging DC power supply 9, and the electric double layer capacitor of the cordless equipment is charged quickly with this charging capacitor 11, so as to provide a time for charging each cordless equipment 1 only required for an extremely short time. By shortening the charging time, a plurality of the cordless equipments can be charged with the charger 2 in its free time. |
