A system for managing power supply devices includes a server including a database and a server end processing module. The server end processing module is configured to receive an alteration request from a user end electronic device and an alteration-confirmation signal from a service end electronic device, and send a confirmation response to the service end electronic device based on the received alteration request and alteration-confirmation signal in order for the service end electronic device to enable a target power supply device to update data stored therein.
