The descrption on the box states all the info, maxell is also a rebadged version of the zens, or a japanese version known as sanwa.
The zens contains a total of 14 coils, 2 for each charging area.
Also note, all 7 coil chargers will need a dedicated charger, they will not run on USB.
A good charger is worth considering is the powerqi which has 3 coils and is powered using USB, you can find more information is the main note 3 wireless charging thread.
