Charging By Induction

Inductive charging use an induction coil to create an alternating electromagnetic field from inside a charging base, and a second induction coil in the compatible smartphone converts the power from the electromagnetic field back into electric current to charge the battery.

Inductive charging is the most popular form of wireless charging and has been built into many smartphones for a few years now. If you have heard of Qi wireless chargers, they work by inductive charging.

How Wireless Charging Works

To use Qi wireless charging, you need a charging pad. Plug the pad into a wall socket and place your Qi-compatible smartphone on it to charge. Wireless pads or plates now come in all shapes and sizes, with some of them coming in the form of small, colourful pillows.

The advantage of wireless charging is convenience: you do not have to plug and unplug your phone. Just drop it on the charging plate and carry on with your business. It is great for work desks, restaurant tables, and home furniture.
