System with electronic device and extension device

According to one embodiment, a system includes an electronic device and an extension device to which the electronic device is detachable from and attachable. The electronic device includes a first battery, and a voltage step-down circuit to charge the first battery with first power supplied from the extension device after stepping down or without stepping down voltage of the first power. The extension device includes a second battery, and a voltage step-up circuit to supply the electronic device with second power supplied from the second battery after stepping up or without stepping up voltage of the second power.

Dock with battery for charging electronic device battery with voltage conversion

According to one embodiment, an electronic apparatus connectable to an external apparatus includes a first connector and a detector. The first connecter is electrically connected to a second connector of the external apparatus. Each of the first connector and the second connecter includes a plurality of terminals. The detector is configured to detect a state of a first terminal of the first connector. The first terminal of the first connector is configured to be set to a predetermined state via at least a connection line connecting two terminals of the second connector to each other while the first connector and the second connector are electrically connected to each other.
