With the D-Link 7-port USB 2.0 Hub (DUB-H7BL), you can instantly add more USB 2.0 ports to your computer. It allows you to connect up to seven USB peripherals - such as digital cameras, printers, external hard drives, mice, keyboards, flash drives, and tablets - to your laptop or desktop. The DUB-H7BL is fully compliant to USB 2.0 specifications with data transfer rates of up to 480 Mbps. It is an ideal solution for transferring data between your computer and USB devices. The DUB-H7BL features two USB fast charging ports that provide high power (1.2 A per port) under fast-charge mode. Taking up only one AC outlet, it gives you the ability to simultaneously fast charge two power hungry devices including iPad, iPhone, tablets, smart phones, and MP3 players. Just connect the DUB-H7BL to a power outlet and a USB port on your computer; it's that simple to add 7 USB 2.0 ports to your computer. The DUB-H7BL is also backward compatible with USB 1.13, ensuring connectivity between your computer and legacy USB devices. If you need more ports, you can connect additional USB hubs to support up to 127 devices.
