The LevelOne USB-0503 USB Hub and Gigabit Ethernet Combo Adapter enables you to connect to the Internet via the USB port of your laptop and at the same time operate other USB peripherals such as MP3 players, digital cameras, printers or memory sticks. The ideal solution for MacBook or other Windows computers that have wireless LAN but do not have their own Ethernet port, but are equipped with a USB or Thunderbolt interface. Sometimes you need a LAN connection to transfer data or gain access to sensitive data. The USB-0503 takes on this task and controls everything via the USB port.
The USB-0503 is compatible with USB1.0, 2.0 and 3.0. It also follows the Ethernet standards 802.3/3u and 802.3ab, which enable Gigabit Ethernet speeds of up to 1000Mbit/s. This speed is suitable for all high-speed broadband Internet connections as well as for fast data transfers on the LAN.
This makes the USB-0503 the best choice for reliability, efficiency and standards compliance.
