Power banks with built-in microUSB cable

MicroUSB

— power banks that have a cable with a microUSB plug.

microUSB is a miniature universal connector widely used in portable electronics: mobile phones, tablets, pocket players, compact cameras, etc. It is used by almost all manufacturers of such equipment, except for Apple with their proprietary connectors (see "Lightning"). However recently microUSB has been gradually replaced by a more convenient and advanced USB type C (see the relevant paragraph) — however, this type of connector is still very far from completely disappearing, so it is still very common in power banks (and USB type C is often provided in addition) .
