4-in-1 USB 3.0 Gigabit Ethernet Hub Adapter, 3 USB 3.0 Ports + 1000Mbps RJ45 LAN Network Dongle, Portable USB Splitter Compatible with MacBook, Surface Pro, Windows, Linux, Chromebook

This all-in-one USB 3.0 hub with gigabit Ethernet combines multi-port expansion and wired network access in one compact device, perfectly solving the shortage of USB ports and lack of built-in RJ45 jacks on thin and light laptops.

It provides three independent USB 3.0 ports for simultaneous connection of mouse, keyboard, U disk, card reader and other peripherals, supporting up to 5Gbps super-speed file transmission. The built-in gigabit network chip supports 10/100/1000Mbps adaptive bandwidth, bringing smoother network experience than unstable Wi-Fi, ideal for online meetings, 4K streaming, large file downloads and design work.

No extra driver installation required for most mainstream systems, seamlessly working with MacBook series, Surface Pro, Windows notebooks, Linux desktops and Chromebook. Mini portable size takes little space in laptop bags, convenient for business trips, school and outdoor office.

Built-in multi-layer shielding structure effectively reduces electromagnetic interference, avoiding network dropouts and signal lag. Intelligent power management chip ensures stable power supply when multiple USB devices run simultaneously, preventing slow speed or disconnection caused by insufficient power. An essential portable expansion accessory for laptops without built-in Ethernet ports.
