PROBLEM TO BE SOLVED: To enable easy backup work of data stored in an internal storage device of a portable information terminal. SOLUTION: When the portable information terminal 1 wherein an SIM card 1b is installed and a power source is turned off is connected to a charger 2, a microcontroller 2a of the charger 2 reads a SIM ID stored in the SIM card 1b of the portable information terminal 1. When the read SIM ID is stored in a SIM ID storage part 2c, the microcontroller 2a stores data stored in a storage device 1a of the portable information terminal 1 in a flashmemory 2b and charges a battery 1d of the portable information terminal 1.
