Inductive charging transfers energy from a charger to a receiver in the back of the phone through electromagnetic induction. BMW sedans and iPhones rely on the same concept as those toothbrushes to catch some wireless juice: inductive charging. Since the 1990s, oral care companies have been embedding wireless charging units right into electric toothbrush stands. Prior to smartphones, smartwatches, and electric vehicles, most applications for wireless charging came down to.
