Emergency power supply for use with electronic device e.g. personal computer, has energy storage device whose charging current is adjusted according to detected power consumption of individual external electronic device

摘要

A distributor (1) comprises several input ports and several output ports (4), such that input port is connected with external power source and output ports are connected with electronic devices. A distribution control device manages data transmission of input and output ports. A power management device is provided between an energy storage device (2) and output port so as to detect power consumption of individual external electronic device. The charging current of energy storage device is adjusted according to detected power consumption of individual external electronic device. An independent claim is included for method for utilizing emergency power supply.
