DC power source and electric load

The invention relates to a DC power source (1). This has a hybrid super capacitor (11), a positive electrical contact element (12) and a negative electrical contact element (13). The contact elements (12, 13) are adapted to connect the DC power source (1) simultaneously with an electrical load and an other similar DC power source (1) electrically. Furthermore, the invention relates to an electrical consumer. This has a first electrical contact element which is adapted to contact the positive electrical contact element (12) of the DC power source (1). Furthermore, it has a second electric contact element which is adapted to the negative electrical contact element (13) of the DC power source (1) to contact.
