Benefits: you don’t have to plug it in.
Drawbacks: slower charging than cable, you have to position it correctly otherwise you wake up to a dead phone, you need a phone back material that the inductive charging will work through, commonly glass, A bit smashy.
As I said already, the ONLY sensible iteration would be if it was the only option to charge an IP68/IP69K 100% Sealed waterproof device. Otherwise WACK! DEAD. MOVE. DUSSOUT. BUN DAT. TEAR. BLURT.
