NFC and wireless charging

[Trippyginger]

I have been looking into wireless charging and I do not quite understand. I have the samsung s4 (quad core) and I want to get a wireless charger for it but I do not understand what exactly I need for it to work correctly. I know you need the charger pad for it to work but with the GS4 do I need anything else? Do I need to get the receiver to put on the battery? I was thinking that NFC would allow me to charge wirelessly but from looking around a bit they seem to have no correlation. I want to get this charger (http://www.amazon.com/UPGRADED-Wireless-Charging-Blackberry-Qi-Enabled/dp/B00C40OG22/ref=sr_1_1?s=wireless&ie=UTF8&qid=1400159370&sr=1-1&keywords=qi+wireless+charger) but do I also need to buy(http://www.amazon.com/Wireless-Charging-RECEIVER-SAMSUNG-Galaxy/dp/B00DK3DC6I/ref=sr_1_3?s=wireless&ie=UTF8&qid=1400159436&sr=1-3&keywords=qi+wireless+charger+galaxy+s4) for it to work?

First off, having an NFC capable phone does not mean it is capable of being charged wirelessly (i.e. the 2 are independent of each other).  The S4 does come with NFC but does NOT come with any hardware for wireless charging out of the box. This means you will need to buy 2 items to be able to get wireless charging working: a wireless pad/receiver and the hardware to put in the phone.  It is important to note that there are different standards  for wireless charging and both items need to be of the same standard.  The most common is QI.

 

For the S4, your best bet is to buy the official wireless charging battery cover from Samsung.  You simply exchange your current cover for it, though it does add some thickness to the device.

 

For the charging pad, you can get whatever QI enabled pad you want.  The one you linked in your post has good reviews.
