— screen, which can display various information about the operation of the power bank. The possibilities of such a display are very limited — usually, these are 2 – 3 digits, sometimes with additional standard inscriptions; nevertheless, they are usually quite enough for extended informing. For example, it can accurately display the charge level in percent, the set operating voltage at the output, report failures (with specification of the type of error), etc. And in general, notifications on the screen are more convenient than indicator lights.
