eKL USB 3.0 Switch 4 Computers Sharing USB Peripherals - Fast Multi-PC

Our review of the eKL USB 3.0 Switch finds it useful for anyone who needs to share a small set of USB devices between multiple computers. The unit's strongest selling point is straightforward: it lets four PCs access up to four USB peripherals with quick switching and true USB 3.0 speeds, which makes it a practical choice for people who alternate between work and personal machines or who maintain separate office and lab systems. Setup is plug-and-play on Windows, Mac, Linux and Chrome OS, and the optional USB-C power input gives peace of mind when using power-hungry devices.

Key Features

• 4-In 4-Out sharing: Lets four computers share up to four USB devices so a single keyboard, mouse and other peripherals can be used across machines without swapping cables.
• USB 3.0 transfer speeds: Supports up to 5 Gbps transfers for fast file movement and low-latency peripherals while remaining backward compatible with USB 2.0 devices.
• 3.5mm audio support: Two 3.5mm jacks accept 3-pole and 4-pole headsets and microphones without an adapter, useful for switching audio along with USB devices.
• Optional USB-C power: An included cable allows external power for more stable operation with high-power devices such as external drives and headsets.
• Three switching modes: Offers desktop control, an onboard button and RS232 control so you can place the unit under a desk or integrate it with automated workflows.

Who It's For

The eKL USB 3.0 Switch is aimed at professionals and power users who regularly move between multiple computers and want a single set of peripherals to work across them. It is especially useful for mixed-OS setups since it works driver-free on Windows 7/10/11, Mac OS, Linux and Chrome OS.

It is less suitable for users who need a video KVM (no video switching) or who require guaranteed enterprise-grade redundancy and support; for mission-critical environments where intermittent failures cannot be tolerated, a higher-end managed switch or separate peripherals may be a better fit.

Pros & Cons

Pros

• Solid build and intuitive multi-PC sharing makes desktop switching seamless for most setups.
• High speed USB 3.0 ports deliver fast transfers and work well with storage and cameras.
• Audio jacks that accept both 3-pole and 4-pole headsets remove the need for extra adapters.
• Optional USB-C power improves stability when using high-power USB devices.

Cons

• Some customers report mixed reliability over time and occasional switching issues, so testing in your workflow is advised.
• The control button and diamond pattern layout can feel non-intuitive to some users compared with a clearly labeled desktop controller.
