Add up to 4 peripherals quickly and easily with the Sabrent 4-Port USB 2.0 Hub. The thin, lightweight design with hide-away cable, makes this hub a great travel companion to expand one USB 2.0 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. Achieve full 480 Mbps on each port, or daisy chain multiple hubs to a maximum of 127 devices. Fully backwards compatible with the USB 1.1 products. Included LED indicates activity. It is possible that the computer will not provide enough power for some power-intense USB devices, so you may require an AC-Powered USB Hub (See Model USB-HWPS).
