To provide a method and system for charging service that reduces burdens on users.
Portable charging units 1a, ..., 1n include charging means 4a, ..., 4n for portable terminals, respectively. Store terminals 2a, ..., 2m where the portable charging units 1a, ..., 1n are placed include input means 5a, ..., 5m and control means 6a, ..., 6m. When model information on a portable terminal is input from the input means 5a, ..., 5m, the control means transmit the model information to a management terminal 3. When specification information on a portable charging unit 1a, ..., 1n is received, the control means allows a predetermined portable unit 1a, ..., 1n to be lent based on the specification information. The management terminal 3 includes: a storage means 7 that relates position information and model information to each portable charging unit 1a, ..., 1n; and a control means 8 that, when model information is received from a store terminal 2a, ..., 2m, refers to the storage means 7 and selects a portable charging unit 1a, ..., 1n corresponding to the position information on the store terminal 2a, ..., 2m as well as the model information thereon and then transmits it as specification information to the store terminal 2a, ..., 2m.
