Abstract
A charger for charging an audio-device-accumulator of an audio device which is wearable on a head of a user and contains an interface for the transfer of electrical energy to the audio-device-accumulator. The charger contains an energy source configured as a hybrid battery for supplying the interface in a first charging mode. The hybrid battery contains a charger-accumulator and a fuel cell.
Claims17
A charger for charging an audio-device-accumulator of an audio device being wearable on a head of a wearer, the charger comprising:
- an interface for a transfer of electrical energy to the audio-device-accumulator;
- and
- an energy source configured as a hybrid battery for supplying said interface in a first charging mode, said hybrid battery having a charger-accumulator and a fuel cell;
- the charger configured to have a first charging mode for charging the audio-device-accumulator of the audio device;
- and
- the charger configured to have a second charging mode in which said charger-accumulator of the charger is charged by said fuel cell.
