Getting energy from radio waves in the air is no small feat and these wireless charging devices manage to do so.

The 'AirVolt' works as a transmitter that creates radio waves and when plugged into a smartphone, converts those radio waves into energy. The device needs to remain within 12 meters of a wall outlet but does not need to be plugged in, although the closer the phone is to the outlet the quicker and more efficient the charge is. The wireless charging devices work almost as well as normal chargers, taking approximately three hours if the average smartphone charger takes two and a half.

This convenient device prevents the user from remaining stationary when charging and simultaneously using their smartphones.
