Add up to 4 peripherals quickly and easily with the Sabrent 4-Port USB 3.0 Hub. The thin lightweight design makes this hub a great travel companion to expand one USB 3.0 port into four. Especially great for notebooks which come with only a few ports in an era when you need to attach many USB devices at once such as a printer card reader cell phone iPod thumb drive mouse keyboard or an external hard drive. Fully backwards compatible with the USB 2.0/1.1 products. Plus each port has its own separate power switch so you can control each port independently.
