Radio waves falls under the category of electromagnetic waves spectrum.(EM waves). EM waves do not require any medium to travel..
But electricity needs a medium to travel(Else think abt our condition, haha)
If u r speaking abt wireless charger:
It's Actually based on Induction of current..There too actually medium exists. So electricity can't travel without a medium
