Abstract: A charger for wireless energy transfer to a personal care device has a travel mode and an internal energy storage, a sensor for detecting a change of position of the charger, and a processor coupled with the sensor for receiving sensor signals relating to a detected change of position of the charger.

Abstract: A personal-care device has a rechargeable energy storage, a charging circuit for receiving energy from an external energy source and for charging the rechargeable energy storage, a first charging mode in which the rechargeable energy storage is charged to a predetermined maximum voltage value, and a user-selectable second charging mode in which the rechargeable energy storage is charged until the voltage at the rechargeable energy source has reached a first predetermined voltage value that is lower than the predetermined maximum voltage value. The present disclosure is also concerned with a system having such a personal-care device and a charger.

Abstract: A charger for charging a rechargeable energy source of a personal care device has a housing having a charging region for positioning the personal care device, a circuit for performing a charging procedure of the rechargeable energy source of the personal care device, a motion sensor for detecting a motion of at least a portion of the charger, preferably wherein the charger comprises a motion enhancer, a controller coupled with the charging circuit and the motion sensor. The controller is arranged to activate the charging circuit when the controller receives a motion signal from the motion sensor indicating a placement of the personal care device in the charging region and/or to deactivate the charging circuit when the controller receives a motion signal from the motion sensor indicating a removal of the personal care device from the charging region.
