Hey guys,
My wife has an Asus Padfone X. It came out of the box PMA ready. AT&T threw in the Duracell charging mat for free like they should be doing with the G3. I bought the padfone at a corporate store.
My Galaxy S3 has a Qi back plate on it. When I put the S3 onto the PMA charging pad, nothing happens. When I put a strip of metal onto the pad to mimic the metal in the padfone and put the S3 onto the pad, nothing happens.
Seems to me that the magnets in the PMA charging pad are there to only help center the device into the charging coil, nothing more. If I place the padfone onto the charging pad slowly, I can feel the slight magnetic pull from the pad.
YMMV. Be nice to see something magical happen with the G3 under the same conditions, but I'm doubtful. Looking at the padfone pma reciever, it's very smooth like a Qi reciever. There is no metal disk in the middle of it.
Be great if the 3rd party manufacturers started selling pma recievers like they do with Qi, but that took about year for the Qi recievers after they were initially introduced.
I think the best solution at the moment is to do what the HTC M8 users are doing. Slipping a USB Qi reciever under the case to add wireless charging. It's cheap & seems to work with cases like Spigen Slim Armor. And it's available now!
