What Is Wireless Charging & How Does It Work?

It is truly a mystery why more devices aren’t using wireless charging. It seems like such a simple idea that has tons of applications yet it’s still not used in many consumer devices. But a more interesting question. How does it work? Wireless charging is not the real name for this technology, it’s real name is “Inductive Charging”. In the process of induction charging the emitter and receiver make use of an electromagnetic field to effectively charge the device(s) wirelessly. There is usually a base station for the charger on which the device(s) that need to be charged sit on top.

A good example of wireless charging that has been around for some time could be the charging system of most rechargeable electronic toothbrushes. Because electronic toothbrushes are usually in close proximity to water it is important that the toothbrush is completely sealed, essentially the removal of physical electrical contacts. And so pretty much all rechargeable electronic toothbrushes these days use wireless or “inductive” charging.

Another notable device that uses inductive charging could be the Google Nexus 4 smartphone. The Nexus 4 has a built in inductive charging plate built in to it’s back cover. You can even get inductive charging kits these days to create the same wireless charging experience on your existing smartphone. You simply attach the corresponding charging plate to your device usually through means of plugging it into whatever port your device uses for charging/data transfer. One notable kit is the Powermat. It supports all kinds of mobile device and allows for simultaneous wireless charging of any device which has been made compatible with the charger.

So overall wireless charging is great. Who doesn’t like to eliminate another wired connection!? It’s just a shame that more companies are not embracing the wireless charging technology. It is just a so much more elegant charging solution (a more elegant solution would be not having to charge the device at all! We can only dream) I think another good idea would be to build in inductive charging into furniture surfaces so there would be no need for the mat either. Imagine simply being able to place your phone on your bedside table (assuming you may have one) and the device charging by simply being there.

I beg of you large companies, make inductive charging a standard!

What do you think? Good idea or a complete waste of time and money?
