With the D-Link DUB-H4BL 4-port USB 2.0 hub, you can instantly add more USB 2.0 ports to your computer. Now you can connect up to four USB peripherals - such as digital cameras, printers, external hard drives, mice, keyboards, flash drives, and tablets - to your laptop or desktop. The DUB-H4BL is fully compliant to USB 2.0 specifications with data transfer rates of up to 480 Mbps.
The DUB-H4BL features a USB fast charging port which is designed to feed high currents of up to 2.0 A to a connected device, when the DUB-H4BL is connected to a power adapter. It gives you the ability to fast charge power hungry devices including iPad, iPhone, tablets, smart phones, and MP3 players. You can quickly charge your iPad with the USB fast charging port when your computer is off, in suspend mode, or sleep mode and the DUB-H4BL will automatically switch from battery charge mode to data sync mode when your computer is back in use.
