The output unit stands with the energy store 3 in operative connection. Such an operative connection can be formed, for example, by means of a button. The output unit is designed such that an optical, acoustic and / or haptic output of the state of charge of the energy store 3 can be done. This enables the user to easily check the state of charge of the energy store 3 get to know.

In one possible embodiment, the output unit comprises at least one luminous element, which is dependent on the state of charge of the energy store 3 emits a light signal. This makes it possible, for example, to determine the state of charge of the energy store via an intensity and / or color of the luminous element 3 to recognize.

In another possible embodiment, the output unit comprises, for example, at least three light elements, each of which is dependent on the state of charge of the energy store 3 output a light signal. This makes it possible, for example, to determine the state of charge of the energy store as a function of the number of lighting elements which output a signal and / or their color 3 to recognize.
