The present invention provides adapter 30 that supplies driving power from battery charger 10, which charges a battery pack, to cableless appliance 70, which is driven by the battery pack, via cable 44. Adapter 30 comprises charger-side adapter 40, which controls a charging voltage and a charging current of charger 10, an appliance-side adapter 45, which intermittently supplies a large current to the appliance 70 by utilizing power accumulated in capacitor C, which is disposed within the appliance-side adapter 45, and cable 44. By allowing a small current to continuously flow in cable 44 in order to charge capacitor C and by intermittently supplying the power accumulated in capacitor C to appliance 70, a large amount of power can be supplied to appliance 70. Accordingly, appliance 70 can be continuously used without the battery pack.
