Abstract
A charging device having contactless transmission of electrical energy in order to supply energy to a wireless hand-held device. An electronic circuit for feeding an inductive energy transmitter is designed to adapt energy fed to the inductive energy transmitter in accordance with energy drawn from the inductive energy transmitter. A hand-held device is designed to interrupt the supply of a load when energy is fed into the hand-held device by means of the inductive energy transmitter.
