An electronic apparatus comprising a charger and an electronic device connected removably to the charger. The electronic device comprises a rechargeable battery unit charged by the charger when the charger is connected to the electronic device, an electronic unit having a plurality of operational modes in each of which a different operating current is required, a charger connection detector for detect- ing the connection of the charger to the electronic device, and a first control unit for calculating an appropriate cur- rent to be supplied from the charger, on the basis of an appropriate operating current value corresponding to the operational mode of the electronic unit and a specified charg- ing current value for the battery unit, and informing the charger of the appropriate supplying current value when the charger connection detector detects that the charger is con- nected to the electronic device. The charger comprises a current supplying circuit for supplying the electric current to the electronic device, and a second control unit for con- trolling the current to be supplied by the current supplying circuit such that the controlled current coincides with the appropriate supplying current when the first control unit informs the charger of the appropriate supplying current value.
