Abstract

The invention provides electronic apparatus includes an antenna, a switch, a power generator, a battery, and a controller. The antenna receives a wireless signal. The switch transports the wireless signal to a first terminal or a second terminal according to a mode selecting signal. The power generator is coupled to the second terminal for receiving the wireless signal. The power generator generates a charging power according to the wireless signal. The charging power is provided to charge the battery. The controller generates the mode selecting signal by detecting the electronic apparatus is in a non-operation mode or not.
