Once wireless charger is plugged into a power source, to charge your device all you need to do is place it down on top of the charger, making sure it’s cantered and charging will commence. Charging will be indicated by an Led light or animation on your phone screen.

Wireless charging stands are similar to charging pads, but hold the device at an angle so it can be viewed while it charges. They work by using inductive charging, which transfers energy wirelessly from the charger to the device being charged. The charger contains a coil of wire that creates an electromagnetic field, and the device being charged contains a coil that picks up this field to charge the battery. Most charging stands use the Qi standard, which optimizes the charging process by adjusting power and speed, and the device can be used and viewed while it charges.
