4-Port SuperSpeed USB 3.0 Hub



4-Port SuperSpeed USB 3.0 Hub



USB 3.0 allows you to transfer data at blazing speeds of up to 5 Gbps - up to 10 times faster* than USB 2.0. You can back up your photos, music, and HD movies to a USB 3.0 external storage device faster than ever before. Each port delivers up to 900mA of power with the included power adapter for faster charging and power hungry USB devices.


Backward compatibility with USB 2.0 and USB 1.1** means that you can connect any USB device to the DUB-1340. Each port automatically detects USB type and transfer data at a maximum rate for each individual port. If you need more ports, you can connect additional USB hubs to support up to 127 devices*.

*Maximum transfer rate based on USB 3.0 specifications. Actual data throughput will vary. To meet USB 3.0 transfer speeds, USB 3.0 Hubs, cables and devices are required.
**Using a USB 1.1 or USB 2.0 port will affect device performance.
