Add up to 7 peripherals quickly and easily with the Sabrent 7-Port USB 2.0 Hub with AC Power. The attractive lightweight design, makes this hub a great travel companion to expand one USB 2.0 port into seven. 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. It is possible that the computer will not provide enough power for some power-intense USB devices, so you may need to use the included AC Power Adapter.
