Wireless charging, also known as inductive charging, is a convenient and fuss-free way to power up your smartphone. Wireless chargers emit an alternating current via a transmitter coil, which then induces a voltage in the receiver coil found in the device. Qi (pronounced “chee”) wireless charging pads are capable of charging smartphones, tablets, Bluetooth® headsets, cameras and portable power packs. Note: You do need one of these pads for wireless charging; a smartphone that says it has wireless charging capability will not charge itself. At least, not yet anyway. But wireless charging is simple: Just plug in the charging pad and place your device on it. That’s it!
