at least one data line having one end electrically connected to one of the USB connectors and another end electrically connected to another one of the USB connectors so that a plurality of electronic devices are configured to exchange electric signals with each other;
a protection circuit module having a printed circuit board at which an external terminal electrically connected to a first one of the USB connectors is formed;
a cable battery including an external input/output terminal electrically connected to an internal terminal of the printed circuit board, an inner electrode layer having a cylindrical shape extending in one direction and formed at an inner center of the cable battery, a separator layer formed at an outer side of the inner electrode layer, an outer electrode layer formed at an outer side of the separator layer, and an inner insulation coating layer surrounding an outer surface of the outer electrode layer; and
an outer insulation coating layer formed to surround at least a portion of an outer surface of the cable battery,
wherein the at least one data line is located at an inner center of the inner electrode layer.

2. The data cable device according to claim 1 ,
wherein at least one of the USB connectors includes a connection terminal at which a plurality of connection pins are formed, and a housing having an opening connected to the connection terminal and having a predetermined inner space formed therein, and
wherein the printed circuit board is included in the housing.

3. The data cable device according to claim 1 ,
wherein a linear protrusion protruding outward is formed on an outer surface of the outer insulation coating layer to extend in a direction along which the outer insulation coating layer extends.

4. The data cable device according to claim 1 ,
wherein the protection circuit module includes a microprocessor unit configured to control a power supplied to the first USB connector to be at least partially supplied to the cable battery so that the cable battery is charged or to control a power output from the cable battery to be supplied to the first USB connector.

5. The data cable device according to claim 4 ,
wherein the microprocessor unit is configured so that a part of power supplied from the outside to one of the USB connectors is supplied to an electronic device when the electronic device is connected to another one of the first USB connectors and needs to be charged, and another part of the power supplied from the outside is supplied to the external input/output terminal of the cable battery so that the cable battery is charged.

6. An electronic system, comprising the data cable device according to claim 1 .

7. A cellular phone, comprising the data cable device according to claim 1 .

8. A data cable device, comprising:
USB connectors respectively formed at opposing ends of the data cable device and each configured to be electrically connected to an electronic device or a battery charging adaptor;
at least one data line having one end electrically connected to one of the USB connectors and another end electrically connected to another one of the USB connectors so that a plurality of electronic devices are configured to exchange electric signals with each other;
a protection circuit module having a printed circuit board at which an external terminal electrically connected to a first one of the USB connectors is formed;
a cable battery including an external input/output terminal electrically connected to an internal terminal of the printed circuit board, an inner electrode layer having a cylindrical shape extending in one direction and formed at an inner center of the cable battery, a separator layer formed at an outer side of the inner electrode layer, an outer electrode layer formed at an outer side of the separator layer, and an inner insulation coating layer surrounding an outer surface of the outer electrode layer; and
an outer insulation coating layer formed to surround at least a portion of an outer surface of the cable battery,
wherein the printed circuit board is a flexible printed circuit board, and
wherein the flexible printed circuit board is interposed between the inner insulation coating layer and the outer insulation coating layer.

9. The data cable device according to claim 8 ,
wherein at least one LED lens is mounted to the flexible printed circuit board, and
wherein the at least one LED lens is exposed out through a portion opened in the outer insulation coating layer.

10. A data cable device comprising:
USB connectors respectively formed at opposing ends of the data cable device and each configured to be electrically connected to an electronic device or a battery charging adaptor;
at least one data line having one end electrically connected to one of the USB connectors and another end electrically connected to another one of the USB connectors so that a plurality of electronic devices are configured to exchange electric signals with each other;
a protection circuit module having a printed circuit board at which an external terminal electrically connected to a first one of the USB connectors is formed;
a cable battery including an external input/output terminal electrically connected to an internal terminal of the printed circuit board, an inner electrode layer having a cylindrical shape extending in one direction and formed at an inner center of the cable battery, a separator layer formed at an outer side of the inner electrode layer, an outer electrode layer formed at an outer side of the separator layer, and an inner insulation coating layer surrounding an outer surface of the outer electrode layer; and
