TJCXELE TJUS-03 4-Port USB Switch
Overview
The TJCXELE TJUS-03 4-Port USB Switch solves a genuinely frustrating desk problem: running multiple computers while sharing the same keyboard, mouse, or printer without constantly swapping cables. One thing worth clarifying upfront — this is not a KVM switch. It handles USB peripherals only; your monitors stay connected however they already are. What sets it apart in its price range is support for both USB-C and USB-A, covering modern laptops and older desktops in a single device. Switching between up to four host computers happens either via a button on top of the unit or through an included wireless remote, which is a more useful pairing than it might sound.
Features & Benefits
The port layout is more considered than it first appears — three USB-A 3.2 ports alongside one USB-C 3.2 port means the 4-port switcher handles nearly any peripheral without hunting for adapters, though a USB-C to USB-A adapter ships in the box anyway. Transfer speeds reach 10Gbps via USB 3.2 Gen 2, which is genuinely relevant when sharing an external hard drive between machines, less so for a keyboard. A Micro USB auxiliary power input helps stabilize high-draw devices that the bus alone struggles with. The wireless remote deserves real credit — stash the unit behind a monitor stand, keep the desk clean, and switch computers without getting up.
Best For
This peripheral sharing hub fits a handful of specific situations particularly well. The clearest match is the multi-PC home office — someone running a personal laptop alongside a work machine, sharing one keyboard, one mouse, and a printer without dedicating separate peripherals to each. It also suits content creators moving between a primary editing rig and a secondary system without yanking cables from external drives. The remote makes it practical when the unit sits tucked away rather than front and center. It is a poor fit for anyone needing display switching, since video output is not part of what this device does.
User Feedback
Buyer impressions of this USB switch tend to follow a predictable pattern. The remote control and consistent switching behavior draw the most appreciation, especially from users who tuck the unit out of reach. Build quality earns a more divided response — the plastic housing feels workmanlike rather than solid, though most find it reasonable given the price tier. Power-related issues surface regularly: connecting an external hard drive without using the auxiliary power port can cause instability, and the documentation around this could be clearer. The lack of hot-key switching frustrates buyers who expected keyboard shortcuts. Cross-platform compatibility with Windows and macOS is generally reported as trouble-free.
Pros
- Supports four host computers simultaneously — far more useful than the typical two-port switcher for busy desks.
- The included wireless remote is a genuine convenience upgrade, not a gimmick, especially for tucked-away setups.
- USB 3.2 Gen 2 at 10Gbps makes sharing an external SSD between machines actually fast enough to be practical.
- Both USB-C and USB-A peripheral ports are covered, so most existing devices connect without adapter hunting.
- A bundled USB-C to USB-A adapter ships in the box, reducing immediate out-of-pocket accessory costs.
- The auxiliary Micro USB power port prevents the instability issues that plague USB switches used with external hard drives.
- Driver-free setup on Windows and macOS means most users are running within minutes of unboxing.
- Peripheral re-enumeration after switching is fast enough that the transition feels natural in daily use.
- The physical button provides a positive, tactile click that confirms a switch without needing to look at indicators.
Cons
- Remote control batteries are not included, which is an avoidable friction point on first use.
- No hot-key switching support eliminates a feature many multi-PC users specifically look for.
- The plastic housing feels lightweight in hand and does not inspire confidence compared to pricier alternatives.
- Only four peripheral ports total means making trade-offs when you have five or more devices to share.
- Included cables are short, often forcing buyers to purchase longer replacements for anything but compact desk arrangements.
- Power supply documentation is vague — many users discover the auxiliary port is necessary only after experiencing dropouts.
- The remote provides no switching confirmation, making it easy to overshoot the intended host without realizing it.
- Linux compatibility is inconsistent and not officially supported, leaving those users in uncertain territory.
- Status LEDs are only useful when the unit is in direct sightline — hidden installs get no meaningful feedback.
Ratings
The TJCXELE TJUS-03 4-Port USB Switch has been evaluated by our AI system after analyzing verified buyer reviews from across global marketplaces, with spam, bot-generated, and incentivized feedback actively filtered out before scoring. What emerges is a nuanced picture — this peripheral sharing hub earns real praise for its switching reliability and remote control convenience, while a handful of friction points around power handling and missing hot-key support keep it from a clean sweep.

Suitable for:
The TJCXELE TJUS-03 4-Port USB Switch is built for people who run more than one computer at a single desk and are tired of physically swapping cables every time they need to use a shared peripheral. The clearest fit is the dual-machine home office worker — someone with a personal laptop and a work-issued machine who wants one keyboard, one mouse, and one printer serving both without a second thought. Content creators who move files between a primary editing rig and a secondary system will also appreciate the USB 3.2 Gen 2 speeds when a shared external drive is in the mix. The wireless remote makes it particularly practical for setups where the unit lives behind a monitor or inside a desk cable tray, since you never need to reach for the device itself. Anyone supporting up to four machines in a small studio or shared workspace will find the four-host design covers most realistic scenarios without requiring additional hardware.
Not suitable for:
Buyers searching for a KVM switch — one that handles both peripherals and monitor output from a single box — should stop here, because the TJCXELE TJUS-03 4-Port USB Switch does not support display switching in any form. If your primary goal is to move between computers using keyboard shortcuts rather than pressing a physical button or picking up a remote, this device will frustrate you immediately, as hot-key switching is not supported and cannot be enabled through software or firmware. Users who need to connect more than four peripheral devices simultaneously will also hit a ceiling quickly, since the switcher offers only three USB-A and one USB-C port on the peripheral side. Those planning to share power-hungry devices like 3.5-inch desktop hard drives should budget for a separate power adapter, as relying on bus power alone introduces instability. Linux users should approach compatibility with caution rather than assuming out-of-the-box reliability.
