JSAUX 4-in-1 Docking Station Review: A Cheap Dock With Limits

A dock turns a handheld into a TV console, and this one is among the cheapest options in the JSAUX range. At $21.99 it covers video, charging, and a controller or keyboard. The trade-offs are clear from the port list.

We have not bench-tested this product. This review is based on the manufacturer's published specifications and listing, checked on November 2, 2026. Prices and stock can change, so confirm both at checkout.

The verdict

Buy it if you mainly want your handheld on a TV over Wi-Fi with a couple of USB accessories. Choose a larger dock if you need wired internet or fast USB storage.

Ports and specifications

• HDMI 2.0: up to 4K at 60Hz, or 2K at 120Hz
• USB-C PD input: up to 100W
• USB-A 2.0: 2 ports
• Ethernet: none
• Design: built-in stand with ventilation at the bottom

What the limits mean

No Ethernet. JSAUX states this directly on the listing. If you stream games or download large updates and your Wi-Fi is weak, this is the main reason to look elsewhere.

USB 2.0 only. That is fine for controllers, keyboards, and mice. It is a poor match for external game storage, where transfers will be slow.

4K at 60Hz is a ceiling. The dock can output that signal, but a handheld will not run demanding games at 4K just because the dock supports it. Expect to lower game resolution for many titles.

Power depends on your charger. JSAUX says the 100W input supports ROG Ally 30W Turbo Mode when used with a recommended 100W charger. A weaker charger may not deliver the same result.

Compatibility

JSAUX lists Steam Deck LCD and OLED, ROG Ally, ROG Ally X, ROG Xbox Ally, ROG Xbox Ally X, Legion Go, Legion Go 2, Legion Go S, and MSI handhelds. Nintendo Switch 2 is not on that list, and JSAUX sells a separate 7-in-1 dock for it at $39.99.

Dock only, or the charger bundle?

The dock is $21.99, or $41.99 with a 65W charger. If you already have a good USB-C charger, the dock alone is the obvious pick. For more ports, JSAUX also lists a 7-in-1 RGB Cooling Docking Station at $55.99, which is worth checking if you need more than this model offers.

What it costs with a code

Code Aalexsale is listed for 5% off, which would bring the dock to about $20.89 if it applies. JSAUX advertises free shipping over $50, so check the shipping cost, since it could outweigh the discount on an order this small.
