USB HUBS

The USB HUBS is also known as a port replicator which is an external device designed for laptop computers. By copying or even extending the port of the notebook computer, the notebook computer can be easily connected with multiple accessories or external devices (such as power adapter, network cable, mouse, external keyboard, printer and external monitor) in one stop.

The USB C Hubs has both the functionality of a port replicator and is used to extend to a considerable degree of desktop functionality. Especially suitable for professionals, such as the need for more interface equipment. Using the laptop docking station for company, home or business presentations can also increase the ease of use and excellent scalability of the notebook. For example, consider using the UltraBay interface on the docking station to obtain an optical drive, burner, battery, numeric keypad, hard disk and other expansion functions.

The biggest use of the mini Type C Usb Hub is port expansion. As it is known to all, laptop computers are much less than desktop computers due to their own size limitations, both in terms of the number of ports and types, and sometimes it is difficult to meet the needs of users. The mini dock, on the other hand, offers multiple port extensions, like a laptop that suddenly has three heads and six arms. Some ports are most laptops do not have their own, such as serial port, PS/2, DVI, IBM dedicated floppy drive port. Some are more numerous than the body of a laptop, such as USB ports. These numerous ports allow the laptop to connect to more peripherals at the same time, improving the performance of the entire laptop and helping to increase productivity.
