JSAUX Steam Deck Dock 100W 4K@120Hz

The JSAUX 5-in-1 dock brings console-style connectivity to handheld PC gaming, pairing high-refresh HDMI with power delivery and wired networking for stable sessions on a big screen. It suits players who want a compact hub to link a Steam Deck, ROG Ally X, Legion Go or MSI Claw to an external display while keeping battery and network performance steady.

Key features

This dock delivers HDMI 2.1 output up to 4K at 120Hz, which reduces tearing and smooths motion on compatible monitors, according to the manufacturer. It also provides up to 100W USB‑C PD charging so your handheld can stay in Turbo Mode without rapid battery drain, and a 100Mbps Ethernet port for more reliable online play than Wi‑Fi. Two USB‑A 2.0 ports let you connect peripherals like controllers or a keyboard, and the aluminium alloy shell offers a neat, sturdy footprint that helps dissipate heat during extended sessions.

Specifications

Benefits

If you frequently move between handheld and desktop setups, this dock simplifies the switch with a single cable to an external display, power and network. The metal construction feels solid without being bulky, and the combination of 4K@120Hz output and full-speed charging helps maintain performance during extended play. Do note that one limitation is USB‑A remains at 2.0 speeds, so large file transfers via those ports will be slow compared with USB 3 options.

How to use it

Connect the dock to a compatible handheld, plug an HDMI cable to your monitor and attach a 100W USB‑C PD adaptor to enable maximum charging. For the best online experience, use the Ethernet port instead of relying on wireless. It’s a good fit if you want a tidy desk setup that prioritises display smoothness and uninterrupted power.
