Power bank batteries with USB hub
USB hub
— the ability of power bank to work as a USB hub (splitter).In this mode, the external battery's own USB connectors work as the USB inputs of a PC or laptop to which the power bank is connected (the connection itself, usually, is also carried out according to the USB standard). This feature is useful primarily in the case when you need to connect additional peripherals to the computer, and there are no longer enough native USB ports for it. In addition, a power bank with this feature can be used as a kind of extension cord with external USB connectors; in some cases, this format of work is also relevant — for example, if there is a free USB port only on the back panel of the PC, which is difficult to reach.
