Abstract
A removably connected power supply for supplying external power to an electronic product. An output unit supplies power to the electronic product. A switching unit selects whether to supply the power to the output unit, and a switching apparatus turns on the switching unit in response to being connected with the electronic product and turns off the switching unit in response to being disconnected from the electronic product. The switching apparatus includes a switch which performs a switching operation in response to the connection or disconnection with the electronic product from the output unit. A switching element controls operation of the switching unit in response to the operation of the switch. Thus, the power supply is operated in a power saving mode and unnecessary power consumption and damage caused by voltage or current spikes are prevented.
