The world is moving towards a wireless future. The wireless charger is one step towards this. Here I'm trying to explain to you working of the wireless charger without any fancy Si-Fi words. Is wireless charger worth buying? I will answer that question too!


How wireless charger works?


Well, Michael Faraday discovered induction and Tesla invented the first induction motor. Wireless chargers work on the same principle of your motors and Dinamo works.

When there is an oscillating magnetic field it induces electricity. Just opposite of fan and motors. This electricity is used to power your device.



Now Is wireless charger is usable?


No doubt, the wireless charger looks damn cool. But the wireless charger is not energy efficient. I mean to say that a lot of energy gets wasted as heat and induction. You also need to align this receiver coil and induction coil perfectly.
