4-Port USB 3.0 Hub Multi-Port Splitter Expansion Adapter Dock, High Speed USB Data Transfer Extension Hub for Laptop, Desktop PC, Notebook, Flash Drive Mouse Keyboard Connection

This 4-port USB 3.0 expansion hub is a practical peripheral expansion accessory designed to solve the problem of insufficient built-in USB interfaces on laptops, ultrabooks and desktop computers. It can convert a single host USB 3.0 port into four available USB 3.0 sockets at the same time, allowing you to connect multiple external devices simultaneously without frequent plugging and unplugging operations.

Compliant with official USB 3.0 transmission standard, the maximum theoretical transmission speed reaches 5Gbps, which greatly accelerates the copying speed of high-capacity files, high-definition videos and compressed folders when connecting mobile hard drives and solid-state flash drives. It is backward fully compatible with USB 2.0 and USB 1.1 devices, ensuring normal identification and stable operation of old USB peripherals.

The hub adopts streamlined mini plastic casing with solid integrated structure, small size and light weight, which can be easily put into backpacks, handbags and office storage boxes, very suitable for office work, student study, business trips and outdoor portable use. The built-in intelligent control chip has over-current, over-voltage and short-circuit protection functions. When an external device has abnormal short circuit, it will automatically cut off the power supply of the corresponding port to protect the host computer motherboard and connected equipment from damage.

It realizes true plug-and-play function, automatically recognizes devices after insertion without downloading and installing additional drivers, perfectly adapts to Windows, macOS, Linux and other mainstream operating systems. It can be widely used to connect USB flash drives, wired mouse, mechanical keyboard, mini cooling fan, USB desk lamp, card reader, printer, scanner and other low-power USB small devices. It is an economical and essential desktop tidying and interface expansion tool for office workers, students and digital daily users.
