<p>PROBLEM TO BE SOLVED: To provide an electronic apparatus, a charger, and an electronic apparatus system, capable of charging a secondary battery by using a regular connection apparatus and thereby securing safety of the charging.SOLUTION: An electronic apparatus 1 comprises: a secondary battery 20; a charging connector P1 connectable with an external charger 30; a switch part 16 electrically connected with the charging connector P1 and the secondary battery 20, and that can switch between conduction and interception; and an authentication communication connector T1 that can receive at least first data. In the case that the first data is predetermined data, and in the case that a voltage of the charging connector P1 is a predetermined voltage, the switch part 16 becomes closed. At least in the case that the first data is not the predetermined data, or in the case that the voltage of the charging connector P1 is not the predetermined voltage, the switch part 16 becomes opened.</p> |
