The NRGkick wall socket is permanently installed on the supply line and serves as a socket or interface for the NRGkick charging unit. No external connections are possible, as the NRGkick wall socket features a proprietary connection interface, ensuring that no unintended devices can be connected to the socket. The NRGkick wall socket is automatically recognized and identified by the NRGkick charging unit. This ensures that the charging current does not exceed the value for which the wall socket is approved.
