Clocking without any gaps, even in the event of a power outage. Guaranteed by the Express docking station, especially designed as an emergency power supply for our clocking system. In the event of a power outage or fluctuations, the power is supplied for at least another 5 hours. This means that the BENZING Express G2 is equipped with a docking station that can be used in lofts that have no mains supply at all. The charged docking station is simply placed in the loft prior to the arrival of the pigeons and connected to the Express G2 and the antennae. Next to the mains power supply, the docking station is equipped with a USB interface, for the purpose of updating the Express G2 or for uploading information.
