Wireless device charging is an exciting mobile trend. This technology is based on on the principle of electromagnetic induction, by which the loading dock creates an electromagnetic field with an alternating electric current. When the device is placed within the field, the induced current is absorbed and energy is transferred to the battery.
To utilise inductive charging, you need a charging pad and a special receiver in your phone. Although many devices have the receiver built in by default, it is even possible to purchase a special back cover and battery that will allow you to convert your phone into a wireless-compatible device. Charging bases tend to be beautifully designed, making them an ornament in their own right.
