Most wireless chargers use magnetic induction and magnetic resonance. They offer to place the gadget on a special surface for automatic charging, without the need to connect the cable to the device. Of course, wireless charging is not really wireless. Your phone, a smart clock, a tablet do not need to be connected to the charging, but the wireless charger itself must still be connected with a cable to the power adapter or USB port.
