Abstract

Disclosed are a charging and discharging device and a terminal. The charging and discharging device (10) comprises: a charging and discharging interface (11) and an interface conductor for external connection (12). The charging and discharging interface comprises an interface shell (111) and a charge discharge circuit (112) built in the interface shell wherein the charge discharge circuit comprises: a battery connection end (1121) a current input end (1122) and a current output end (1123). One end of the interface conductor for external connection is electrically connected to the battery connection end and the other end thereof is electrically connected to a battery of a first terminal (13). The current input end is used for connecting to a current output end (2123) of a second charging and discharging device (20) so as to charge the battery of the first terminal the second charging and discharging device being electrically connected to a second terminal (23). The current output end of the charge discharge circuit is used for connecting to a current input end (2122) of the second charging and discharging device so as to output electric energy in the battery of the first terminal. The charging and discharging device realizes mutual charging between terminals improving the user experience.
