The lighting will be activated as soon as a locker is opened. The lighting consists of 6 high-power LEDs, integrated into the lock. Apart from the integrated lighting, there is a standard option of charging a mobile device via a USB port. In order to charge current smartphones, a minimum of 1A charging capacity is required. The lock has a charging capacity of 1A via the USB port to facilitate charging in the locker. A variety of USB charging options may be made available via the Locker Management System for individual lockers, individual employees, groups of employees, or locker blocks. For safety reasons, the USB port cannot function as a data port. If at a certain point in time, a large number of employees are charging their smartphones simultaneously, thus causing a peak load, the power supply will be regulated to avoid an overload.
