Abstract
A charging system may be provided that include an adapter to receive an external power and to provide an output voltage, and a charging device to receive the output voltage and to provide a wireless power. The adapter may adjust the output voltage based on feedback information. The charging device may include a power amplifier to receive the output voltage directly from the adapter, a power transmitter to transmit the wireless power, a wireless communication device to receive power information from an external electronic device, and a feedback device to provide a feedback signal or feedback information to the adapter based on the power information.
