The UGREEN 4-Port USB 3.0 Switch Box (30768) is a precision-engineered sharing solution designed for users who operate multiple computers but want to maintain a clean, single-set workspace. By allowing up to two systems to share four USB 3.0 peripheral devices—such as printers, scanners, keyboards, mice, or USB disks—it transforms how you manage your hardware across different machines. Performance is at the core of this device, featuring USB 3.0 technology that supports ultra-fast data transfer rates of up to 5Gb/s. This is ten times faster than USB 2.0, ensuring a flawless experience with high-bandwidth devices like external hard disks, high-resolution webcams, and digital video cameras. For maximum versatility, it remains fully backward compatible with USB 2.0 and USB 1.1 devices. Designed for immediate utility, the switch is plug-and-play compatible, requiring no additional driver installations. It is USB bus-powered, meaning no power adapter is required for basic operation, though a standard DC 5V USB power adapter can be used for enhanced stability with power-hungry peripherals. Control is simple and manual; a dedicated switch allows you to select the active computer port instantly. The package includes 1.5M cables to connect the switch to your computers, ensuring a reliable connection. Whether you are a creative professional switching between a Mac and a PC or a gamer managing two systems, this switch provides a concrete, hardware-based solution to workspace clutter.
