Abstract
A device for supplying power to an external data medium reader unit, in particular a CD-ROM and/or hard disk drive, connected to a computer via a first port, in particular a PCMCIA port or a parallel port. The device includes an energy store means charged by the first power supply voltage source (Vcc), a current limiting circuit connected between the first power supply voltage source (Vcc) and the energy store means, and a circuit for raising the output voltage of the energy store means to a first voltage level required for the power supply of the logic components of the external reader unit.
