1. A wireless charger, comprising:
- a RF conversion unit that receives radio frequency (RF) from a wireless power transmitter wirelessly connected to the wireless charger and generates alternating current (AC) electricity; and
a voltage conversion unit that is connected to the RF conversion unit and coverts the AC electricity to direct current (DC) electricity and charges an electronic device using the DC electricity, and the electronic device being wired to connect to the wireless charger;
wherein the wireless charger further comprises;
a switch device, a voltage sensor and an interface, the switch device comprising a first switch and a second switch;
the voltage sensor being connected to the RF conversion unit, the switch device and the interface;
the voltage conversion unit being connected to the first switch; and
the interface being connected to the second switch and a wired charger;
both of the first switch and the second switch being connected to the electronic device;
wherein the voltage sensor controls the first switch to turn off and controls the second switch to turn on, and thus the wired charger charges electronic device; and
alternately, the voltage sensor controls the first switch to turn on and controls the second switch to turn off, and thus the wireless charger charges the electronic device.
