This portable USB 3.0 hub gives you an easy way to add four USB 3.0 Type-A ports to your laptop, with individual power switches to save power. The USB port expander plugs easily into your laptop’s USB Type-A port. Plus, it’s bus-powered for easy portability.

Connect Your Current USB Devices

Use your existing USB 3.0 devices such as flash drives, mouse, keyboard and external hard drives. The 4-port USB 3.0 hub expands your computer’s USB Type-A port into four USB 3.0 (Type-A) ports, and it’s backward compatible with your older USB 2.0 devices. (USB 3.0 is also known as USB 3.1 Gen 1.)

Individual On/Off Switches

Each port on the USB 3.0 hub has its own power switch so you can turn off devices when they’re not in use. That means you can better manage power consumption for your USB devices, without having to physically disconnect the device or cable.

Easy Portability

With its compact, lightweight design, this hub is perfect for portable use. The versatile USB to USB hub is bus-powered, with no need for an external power adapter. You can travel lighter with fewer cables to carry with you.

Plug and Play

The 4-Port USB 3.0 hub installs automatically when you connect it to your laptop, so you can be up and running in seconds.

HB30A4AIB is backed by a 2-year warranty and free lifetime technical support.
