Wireless charging

Ever since I bought my first electric toothbrush several years ago, I wondered what it would take to incorporate similar wireless charging capabilities into phones, wearables, gaming controllers, etc.  The toothbrush doesn't have any exposed electrical contacts.  You just place it on its base station and it just charges using induction.  What if we could use similar technology to charge any other device.  Throw your phone on a mat and it charges itself.  You don't need to worry about carrying your cable.  you could potentially charge any kind of device on a single mat.  Wouldn't that be great?

Well, several companies are already making such chargers using inductive or resonant charging technology.  One of the reasons for the slow takeoff is the competing effort of three bodies: Alliance for Wireless Power (A4WP), Power Matters Alliance (PMA) and Wireless Power Consortium (Qi). 

Good news is that A4WP and PMA decided to merge this week.  Yay! 

As long as we have fewer competing standards and hopefully, everyone will agree to just one standard.  This will pave the way for wireless charging to charge ahead and make a breakthrough.  Having one standard will allow the utopian charging pad which can be used to charge any kind of device. 

Looking forward to wireless charging on all the devices in the near future.
