1. A first power receiving device comprising:
a housing;
a battery disposed in the housing;
a power management integrated circuit operatively connected with the battery;
an interface for receiving power from a power supply device; and
a processor electrically connected with the battery, the power management integrated circuit and the interface, and configured to control a charging current using the power management integrated circuit,
wherein the processor is further configured to:
receive, from a second power receiving device paired with the first power receiving device, information associated with a level of a battery in the second power receiving device, through the power supply device,
control the charging current based on a comparing a level of the battery in the first power receiving device with the information associated with the level of the battery in the second power receiving device, and
transmit information associated with the level of the battery in the first power receiving device to the power supply device, such that the second power receiving device receives the information associated with the level of the battery in the first power receiving device through the power supply device and controls a charging current of the second power receiving device based on a comparing the level of the battery in the second power receiving device with the information associated with the level of the battery in the first power receiving device.
