Well if resonant based charging can ultimately win the standards battle versus Qi (standard magnetic induction), then you could have some spatial freedom to move around and still get efficient charge. Qi has had first mover advantage in consumer electronics, while resonant charging seems to be taking hold in the wireless vehicle charging sector.
