First Claim
1. A portable charger comprising:
- a main body;
a first connector connected to the main body and a commercial power source; and
a second connector connected to the main body and an external apparatus,wherein the main body comprises;
a power line formed between the first and second connectors to allow a commercial electric power to flow through the power line;
a relay disposed on the power line to intermit the commercial electric power flowing through the power line;
a data communication unit connected to the power line to perform data communication with the external apparatus connected to the second connector through the power line; and
a switch disposed between the power line and the data communication unit to intermit the connection between the data communication unit and the power line,wherein the power line comprises;
a first power line through which a positive first electric power flows; and
a second power line through which a negative second electric power flows,the relay comprises;
a first relay intermitting only the first electric power which flows through the first power line; and
a second relay intermitting only the second electric power which flows through the second power line, andthe data communication unit comprises;
a first data communication unit performing data communication through the first power line; and
a second data communication unit performing data communication through the second power line,wherein the switch comprises;
a first switch independently intermitting a connection between the first power line and the first data communication unit;
a second switch independently intermitting a connection between the second power line and the second data communication unit; and
a third switch intermitting a driving electric power supplied to the second data communication unit.
