Product information

Description

The StarTech.com ST3300GU3B is a portable USB 3.0 hub that adds three external USB 3.0 ports and a Gigabit Ethernet port to a laptop or Ultrabook through a single USB 3.0 connection. Housed in a compact black aluminum casing with an attached USB 3.0 cable, the hub combines 5 Gbps USB data transfer and a GbE network interface for wired network access and peripheral expansion without needing a separate cable.

Advantages

This compact hub delivers three additional USB 3.0 ports with UASP support and an integrated Gigabit Ethernet (IEEE 802.3/u/ab) port over one USB 3.0 host connection. The integrated cable and lightweight aluminum construction make the device travel-friendly while the GbE port supports Wake-on-LAN for remote wake capabilities. A universal power adapter is included to support higher-power devices such as external hard drive enclosures.

Suitable for

Expanding connectivity on Ultrabooks and laptops with limited ports (for example Surface Pro, Surface Book, Dell XPS)
Connecting low-power peripherals: mouse, keyboard, USB flash drives
Providing wired Gigabit network access for stable, high-speed networking
