Black Box USB-Powered Gigabit 4-Port Switch with EU Power Supply

Meet the Black Box USB-Powered Gigabit 4-Port Switch with EU Power Supply — a compact, plug-and-play network expansion that makes wired speeds accessible without clutter or complex setup. Built for modern workspaces, this four-port switch powerhouse is designed to attach to a PC, laptop, or small router to extend a high-bandwidth backbone to printers, NAS, media hubs, gaming consoles, and more. It uses true gigabit Ethernet, with four autosensing ports that automatically adjust to 10, 100, or 1000 Mbps, delivering consistent performance with minimal latency. Because it's USB-powered, there is no need for a power outlet near your equipment; you can draw power from a USB port on your computer or opt for the included EU power adapter for reliable operation in office environments or when USB power from a host is limited.

The device is intentionally compact and silent—no fans, no noise, just steady network throughput. Its slim profile fits beside a router on a desk or shelf, and the simple, rugged housing is designed to withstand daily office life. The auto-negotiating ports support half-duplex and full-duplex modes, enabling optimal speed negotiation with each connected device, whether you’re linking a desktop PC, laptop, game console, smart TV, network printer, or a network-attached storage device. Being unmanaged, there are no configuration menus to wrestle with; it simply works from the moment you plug it in, so you can focus on productivity rather than network management. The EU power supply included in the package ensures compatibility with European outlets and a stable power source, while USB power is ideal for on-the-go setups, demonstrations, or temporary expansions in classrooms or meeting rooms. The switch’s low power consumption further adds to its appeal for energy-conscious users. In short, this 4-port USB-powered gigabit switch is a practical upgrade for any small network that values speed, simplicity, and space-saving design.
