Anything 'not using wires' to connect the devices/power sources/network/whatever is 'wireless'. You're using a stipulative definition of wireless, I think. Not sure.

What do others think?

Wiki: The term wireless is normally used to refer to any type of electrical or electronic operation which is accomplished without the use of a "hard wired" connection.

when you consider that the key to this device actually operating is that your device needs to be "fitted internally or externally with an adapter... ". Unless this also acts as a transformer then its pretty much useless. I can't see manufactures integrating internal adaptors in their devices either since it increases the device size and introduces heat.

Induction is easier to make waterproof than metal wires.
