PROBLEM TO BE SOLVED: To provide a power supply system, including a rechargeable battery pack and an attachment apparatus. SOLUTION: The power supply system which supplies electric power to an electronic device, having a first battery, includes the battery pack (100) and the attachment apparatus (300). The battery pack includes at least one first recess (221), a second battery inside a body (110), and a first circuit (500) which dynamically changes the charging current supplied to the second battery, based on the power consumption level of the electronic device, and at least one second circuit (600) which dynamically switches the electronic device between a charging state and a non-charging state, depending on the state of the battery pack. The attachment apparatus includes a frame (310), an extension (350) protruding from the frame, and attachment features (461), suitable for working with the recess to attach the battery pack, and the attachment apparatus to each other and to the electronic device.
