4 Port Portable SuperSpeed USB 3.0 Hub with
Built-in Cable
Product ID: ST4300PBU3
This 4-Port Portable USB 3.0 Hub with Built-in Cable turns a single USB 3.0 port into four, letting you
connect more of your devices to your computer.
The hub features a built-in, 25 cm (10 in) cable that is longer than what most traditional hubs offer. The
extended-length cable gives you the flexibility to place the hub and your devices exactly where you want
them, and it ensures the hub can connect to your laptop or tablet regardless of where the laptop’s USB
3.0 port is located.
Expand the connectivity of your laptop when you travel
This portable USB 3.0 hub is great for adding extra ports to your laptop, tablet, Microsoft Surface Pro 4,
Surface Book, and other Microsoft Surface products.
With an integrated cable you have more flexibility to place the hub on your desk as desired. Plus, the hub
is USB-powered for easy transport when you travel.

Upright port-configuration saves desk space
This USB hub offers a block-style design with ports placed across the top surface of the hub. With upright
port access your connected devices (for example, flash drives and mouse and keyboard wireless
receivers) take up less desk space.
Alternatively, you can lay the hub on its side for easy cable connections to devices like external hard
drivers or printers.
Designed for easy use
With its compact design, you can easily position the USB 3.0 (also known as USB 3.1 Gen 1) hub on your
desk or workspace to make your USB devices more accessible. There’s also ample space between the USB
3.0 ports, so it’s easy to plug and unplug the devices you use the most.
The USB 3.0 hub is natively supported in virtually all operating systems, which makes for an easy setup
with no driver installation required. And because it’s backward compatible, you can connect both new and
legacy USB devices (for example USB 2.0 peripherals).
The ST4300PBU3 is backed by a StarTech.com 2-year warranty and free lifetime technical support.
