I've seen some doozies before, but this one might take the cake!
7.5W per device up to 6 devices at a distance of 5ft with a tiny "magnet" stuck to a micro USB plug.

And they stole the photo of their "test gear" from Alibaba

So they are energy harvesting RF in order to run the Bluetooth chip?
Good luck transmitting without a bulk power storage source.

Those magnets are magnetic charging connectors, which are nice to use, but yeah has no coil or anything inside... you must connect the corresponding pogo pins to mate with the connector of course.
