1. A wearable device worn on a user's body, the wearable device comprising:
a plurality of power receivers in which at least first and second batteries are mounted, the plurality of power receivers being configured to wirelessly receive power from the first and second batteries;
a power supply manager configured to monitor states of the mounted first and second batteries;
a communication interface configured to wirelessly communicate with the mounted first and second batteries;
a display configured to provide information to a user;
a plurality of limiters configured to limit the power received by the plurality of power receivers; and
a controller configured to control the plurality of power receivers, the power supply manager, the communication interface, the display, and the limiters,
wherein the power supply manager is configured to acquire information of remaining power storage amounts of the mounted first and second batteries through the communication interface, and
wherein, when it is determined that the remaining power storage amount of the first battery in use is smaller than a threshold, the wearable device is configured to switch a power receiving system from the first battery in use to the second battery in standby, and display, on the display where side of the first battery is mounted, a warning prompting the user to replace the first battery in use.
