THIS IS SO IRRITATING. Where the hell is A4WP and actual wireless charging and not this "amazing" 4.5 cm future wireless charger?

Agreed, I remember read that A4WP and PMA were merging, but I have seen much devices with either

And what is the range promised of A4WP? If I recall correctly, their development was simply multiple devices (Qi just did it with V1.2) at higher power and no mention of an actual range. I could be wrong but I'll need a link to believe it.

Nice! Especially for people who want to use cases
What about speed?
As far as I know the best Qi chargers are 1A, which is much less compared to the best wired which are 2A

Samsung Qi charger is rated at 2 amps but I'm not sure I believe it. A good question. 1 amp is sufficient for me but I certainly understand the advantage and importance of 2 amps.

Yea, my Nexus 5's wired charger is 1A, havent had any issues with it
But of course I wont mind if it was faster
Thanks I didnt know Qi charging was capable of 2A

I believe the Qi charger have 50% efficiency rate. Meaning a 2A usage of power, but 1A receive on the phone.

According to a paper at WPC, it's more efficient than the using the typical USB cable:http://goo.gl/KXO3A5

I really hope that one day all this wireless charger, can charge up to 50cm. So that I can put my phone in my pocket while driving, and won't left my phone in the car because I'm charging it. and the passenger can use the phone while using it.
