To add a wireless battery charging to the mobile device that do not initially support this function, it is usually necessary to replace the cover, covering the battery compartment. The new cover will then be thicker than usual, because it built on the components required for wireless charging. Here is the case of Samsung Galaxy S4.
WiQiQi idea is to place a receiver under the standard cover. To do this, the receiver is very thin. To install it, you will need to open the cover and to put the receiver with battery contacts and close the device.
Set with the charger and receiver WQS4 (WiQiQi for Samsung Galaxy S4) is priced at $ 88, set WQS3 for Samsung Galaxy S3 - at $ 78, set WQN2 to Note 2 - $ 88.
Deliveries of WiQiQi for Samsung Galaxy S3 and Note 2 will begin this month, for Samsung Galaxy S4 - in the middle of June.
