Has anyone from the arduino community looked into creating a fast phone charger, for example for any of these phones: http://www.phonearena.com/news/Phones-with-quick-charge-the-fastest-charging-from-0-to-100-2016-edition_id81675
As I understand it the charger and the phone need to communicate before the voltage is upped from 5V to 9V, I'm mostly interested in this communication:
Firstly (I can always hope ;) ) has anyone already done this and written up a library for it?
What protocols are used or how are these found?
Is it the same for each phone type, will any library need to be updated for every new phone on the market?
Any rumours of other changes to charging protocols that are planned, for future proofing any project in this (even higher voltages maybe?)
