Abstract: A quick charger for a vehicle performs normal charging or quick charging depending on whether a device connected thereto supports quick charging. The quick charger includes: an input terminal receiving power from a vehicle; an output port configured to be connected to an electronic device and comprising a power port and a communication port; and a charging voltage changing module configured to convert a voltage of the power applied to the input terminal into a normal charging voltage or a quick charging voltage larger than the normal charging voltage, depending on a level of a voltage sensed at the communication port connected to the electronic device, wherein the electronic device is charged with the normal charging voltage at a normal speed and is charged with the quick charging voltage at a faster speed than the normal speed. With the above-described configuration, the quick charger can automatically perform normal charging or quick charging depending on the type of the electronic device connected thereto.
