Basically, what this thing is is a separate battery that gets charged from the USB port. The Wifi-charging thing, if it works at all, will be useless because it would take a very, very, very long time to charge that way. That is, it's a useless feature.
I'm guessing is that the "wifi charging" stuff is just a publicity stunt.

Wireless recharging would only be practical for very, very short distances. You won't see charghing from a cell tower because the cell tower would have to put out
millions of times more power than they already do! And the vast majority of that energy is radiated uselessly (very, very little of that energy is received by devices).
