I don't understand of what you guys are talking, but NFC hardware is not for charging phones or any device, NFC is just comunnicating hardware in between two devices that sends/recieved data requested...it can activate a charging device if nokia has planed for it....but as much as i have see a video on youtube dismantling N9? i saw the wires built in it i gues 99% was for charging purpose...but anyway...what do you need that kind of charging...i guess is slower than USB cable that takes 3h to cimplet charge your phone...and charging pad will take longer for sure.
Otherwise it is posible to build one charging pad by yourself by using power of about 12v in mounted bunch of tiny wire..and hope your phone will activate charging...sorry for my grama...!
