Portable illuminating and charging device with touch switch

A portable illuminating and charging device with a touch switch including includes a housing (1), at least one light emitting element (2), a touch control unit (3), and a discharging output interface (4) is revealed. The housing (1) consists of a main body (12) and a cap body (13) connected with each other and respectively with a close receiving space (11). The light emitting element (2), the touch control unit (3) and the discharging output interface (4) are arranged in the receiving space (11) of the cap body (13). The touch control unit (3) is formed by a touch control board (31) and a sensor (32). The touch control board (31) is electrically connected to the light emitting element (2) and the sensor (32) respectively. Thereby the touch control board (31) generates signals for conduction of circuit between an electrical storage device (5) and the light emitting element (2) to illuminate when users lightly touch the cap body (13) of the housing (1) and the sensor (32) is triggered.
