So What is Wireless Charging?

It’s where you place your phone on a charging mat instead of having to plug in your suddenly gauche charging cable. If you want to be precise, call it inductive charging. If you have an electric toothbrush, then you already use inductive charging — your toothbrush charges when it’s simply placed on its charger…

… In short: It’s a technology that allows charging over (very) short distances without cables.

How does it work?

Wireless Charging isn’t really a completely new technology. Electric toothbrushes have been using the principles of inductive charging for many years. Wireless Charging uses a resonant inductive coupling between the sender (the charging station) and the reciever (the mobile device).

Generally speaking, once compatibility and energy requirement have been calculated, the charging through induction begins. During charging the sender and receiver remain in contact and switch into standby mode as soon as the battery is fully charged.
