Abstract: A charging control circuit includes a switch circuit, a charging circuit, a central processing unit (CPU), and an identification circuit including two monitoring points for being connected to a first or second electronic device, and a mechanical switch connected between the two monitoring points. When charging the first electronic device, the mechanical switch switches to a first state where a voltage drop is generated on the two monitoring points respectively, and the switch circuit is turned on. When charging the second electronic device, the mechanical switch switches to a second state where the connection between the two monitoring points is short circuit, and the switch circuit is turned off. The CPU enables the charging circuit when the switch circuit is turned on or off to provide power to the first or the second electronic device via the charging unit.
