1. A power reception method of a wireless power transmission system, comprising:
- receiving, from a first source device, a first charging power to be used to charge a target device, the target device located within a first magnetic coupling zone of the first source device; and
receiving, from the first source device, or a second source device, or any combination thereof, the first charging power, or a second charging power to charge the target device, or any combination thereof, respectively, based on a transmission efficiency of the first charging power and a transmission efficiency of the second charging power, if the target device moves to a second magnetic coupling zone of the second source device.
