Abstract
An object is to provide a system for improving convenience for users, by which a portable electronic device or the like can be charged even in a place where utility power is not available. Another object is to provide a system which allows a service provider to easily perform customer management. A wireless power supply system includes a power storage device having a power storage portion, a terminal charging device for wirelessly supplying electric power to the power storage device, and a management server having user information. Electric power can be supplied to specified users by intercommunication of user information between the power storage device and the terminal charging device and between the terminal charging device and the management server.
