Jsaux 12-in-1 USB4 Docking Station Review

The Jsaux 12-in-1 USB4 Docking Station brings USB4's 40Gbps bandwidth to a budget-friendly dock with 12 ports, dual 4K output, and an unusual legacy VGA port, priced well below most Thunderbolt-branded competitors.

Jsaux built its name selling inexpensive cables and hubs before moving into full docking stations, and the pricing strategy carries over here: USB4-class bandwidth, similar in practice to Thunderbolt 4, at a price closer to a basic USB-C hub. The inclusion of a legacy VGA port is unusual for a modern dock and specifically useful for connecting to older projectors and conference room displays that haven't been upgraded to HDMI.

Comparison to Alternatives

Against the CalDigit Element Hub, the Element Hub is Thunderbolt-branded with CalDigit's reputation but offers no video output at all, while the Jsaux delivers dual 4K display support, GbE, and even legacy VGA for a similar price. Against the StarTech.com 2-Port Thunderbolt 4 Hub, the StarTech is a bare-bones port expander with no display or charging support, while the Jsaux is a fuller-featured dock aimed at budget buyers who still want display output.
