In-Depth U.S. Market Review
The UGREEN 4-Port USB 3.0 Switch for Two Computers is the quintessential workhorse for the contemporary home office. It’s an incredibly simple yet highly effective device designed to solve the common problem of sharing peripherals like printers, scanners, or external hard drives between two separate computers. If you frequently jump between a work laptop and a personal desktop, or even two different client systems, this small box is the key to maintaining a clean, productive, and hassle-free setup. This USB switch is the ultimate budget monitor choice when it comes to peripheral management.
Compared to a full-blown KVM switch, this UGREEN 4-Port USB switch focuses purely on data transfer, skipping the video switching component to offer a more affordable and straightforward solution. You get the benefit of modern USB 3.0 speeds, ensuring that your peripherals, especially high-speed storage devices, operate at their maximum potential. This makes it an invaluable tool for dual-system users in the U.S. market who prioritize peripheral sharing speed over integrated video switching.

1. Data Transfer Speed and USB Protocol
The biggest advantage of the UGREEN 4-Port USB 3.0 Switch is its reliance on the USB 3.0 standard, often called SuperSpeed USB. This protocol delivers a maximum theoretical data rate of 5 Gbps, which is about ten times faster than USB 2.0. When you connect peripherals that involve significant data flow, like an external SSD or a high-resolution 4K webcam, you will notice a substantial difference in performance and responsiveness.
You can confidently use this switch for high-demand tasks, such as backing up large project files onto an external drive or quickly importing photos from a card reader. The switch maintains a stable connection, and the seamless transition ensures that your work is not interrupted by slow handoffs between computers.
2. Connectivity and Power Management
With four available USB 3.0 output ports, you can connect a comprehensive peripheral ecosystem. Most users will dedicate one port each to their keyboard and mouse, leaving two open for shared devices like a multifunction printer/scanner combo or a portable hard drive. This allocation is usually more than enough for most dual-PC office setups.
For peripherals that draw more power than a typical keyboard/mouse combo, such as certain external hard disk drives, the switch includes a Micro-USB port for optional auxiliary power. You can connect a standard 5V adapter (not always included, so check the package) to ensure that the bus power remains stable, which prevents devices from dropping connection or failing to initialize during the switch.
3. Ease of Use and Desktop Footprint
The physical design of this USB switch emphasizes simplicity and convenience. Switching between Computer 1 and Computer 2 is accomplished via a single, prominent push-button on the top of the unit, accompanied by LED indicators that clearly show which computer is currently active. The tactile click of the button provides confirmation that the switch has occurred, adding reliability to the process.
The device itself is very compact, allowing you to easily tuck it away on or under your desk, minimizing its presence in your professional workspace. Since it’s purely a USB data switch, the setup is true plug-and-play, requiring no drivers on Windows, Mac, or Linux systems. You can literally plug in the two included USB 3.0 A-to-A cables, connect your peripherals, and begin sharing instantly.
