Auxiliary power supply unit and portable electronic system
First Claim
1. An auxiliary power supply unit which is mountable to a portable electronic device having a battery, comprising:
- at least one capacitor; and
an I/F connector which is connectable to an I/F connector of said portable electronic device, said I/F connector comprising power terminals connected to said battery;
wherein said I/F connector of the auxiliary power supply unit includes power terminals connected to said at least one capacitor;
wherein said at least one capacitor is connected in parallel to said battery when said auxiliary power supply unit is mounted to said portable electronic device via said power terminals of said I/F connectors; and
wherein, when said at least one capacitor is connected to said battery in parallel, said at least one capacitor discharges to supply power to said portable electronic device when said portable electronic device is in operation, while said battery supplies power to said at least one capacitor to charge said at least one capacitor.
