Share one USB device between two computers without unplugging: allows two PCs to use the same printer or other USB peripherals, eliminating repeated plug/unplug cycles that cause wear and interruptions. This protects equipment and reduces office costs. Durable construction: black ABS case provides drop resistance and wear protection for reliable, longterm use. Broad device compatibility: designed to work with a wide range of USB devices (printers, scanners, external drives, label printers, etc.), improving flexibility across typical office and home setups. Stable, smooth switching: built around a performance main control chip and intelligent control circuitry for stable operation, compatibility, and seamless switching between connected computers. Spacesaving design and easy placement: compact footprint fits on a desk or near equipment without taking much space. Improves workflow and efficiency: reduces interruptions, speeds device access for two users, and lowers maintenance and replacement costs by avoiding repeated cable handling. Typical use scenarios Shared office printer: Two desktop computers share a single printer. Users switch printing without unplugging cables, reducing downtime and protecting ports and cables. Home or remote work setup: A laptop and desktop share an external hard drive or scanner for quick file transfers and document scanning without moving devices or reconnecting cables. Small business or classroom: Multiple workstations alternate access to a label printer, receipt printer, or other USB peripherals to cut equipment costs and simplify device management. Operation notes Intelligent control chip coordinates clean, stable switching between the two computers. Compatible with most USB peripherals; place the unit on a desk or near devices for convenient access.
