Can anyone explain how an electric toothbrush charging system works? I know it uses inductive charging but I can't find a detailed explanation anywhere that really describes the process. How does it take 120V AC and turn it into 1.5V DC for the battery? How far can the voltage travel across the inductors? Could the inductors be 2 inches apart and still receive power? Does anyone know a place that describes the process?
Much thanx!!
