— classic microUSB connector. This option is convenient because microUSB is used in many modern gadgets, and a huge number of chargers, cables and adapters have been released for this connector. In fact, this means that if the “native” charger is out of order or lost, a third-party charger can be found for the power bank without much difficulty. On the other hand, such a connector is less convenient than USB type C (the plug must be inserted with a strictly defined side), and also has more limited capabilities — in particular, it is poorly compatible with some fast charging technologies.
