Power bank batteries with lamp

Lamp

— a built-in light source, usually in the form of an oblong panel of several LEDs; such a panel can be made foldable. Unlike flashlights (see the relevant paragraph), lamps provide not directional but diffused light, which has a shorter range but covers a larger area. Such lighting can be useful, for example, for reading, illuminating a room during an emergency power outage, and even for creating a certain atmosphere.
