External battery pack apparatus
First Claim
1. An external battery pack apparatus for providing a portable appliance with a power-supply voltage, comprising:
- an adapter for containing a power-supply terminal and output voltage setting terminals, and programming an output voltage by short-circuiting or open-circuiting at least one pair among the above terminals;
a cable connected to the adapter; and
a main body for containing a battery, a charging controller for charging the battery, and an output controller for performing a DC-to-DC conversion on a voltage charged in the battery and outputting the DC-to-DC converted voltage to the adapter via the cable, detecting a programming status of the adapter, and varying an output voltage in response to the detected programming status.

10. An external battery pack, comprising:
-
a cable having an adapter for providing a portable appliance with a power-supply voltage;
a battery;
a charging controller for charging the battery;
an output controller for performing a DC-to-DC conversion on a power-supply voltage generated from the battery, and transmitting the converted voltage to the cable;
a central controller for controlling the charging controller, and checking a charging/discharging state of the battery; and
a communication port connected to the central controller, for transmitting information of the charging/discharging state of the battery to a portable appliance.
