Handheld docking station

The JSAUX HB0603 is a 6-in-1 docking station designed for Steam Deck OLED and LCD, ROG Ally and Ally X, Legion Go, Go S and 2, MSI Claw and 8 AI+, and OneXPlayer devices. It adds HDMI 2.1 video output, three USB 3.0 ports, gigabit Ethernet and 100 W power delivery through a single USB-C connection. The gray unit weighs 170 grams and measures 20 mm thick.

Build integration

Connect the dock to your handheld with its built-in USB-C cable, then plug in an external display, wired network and USB peripherals. The HDMI 2.1 port drives 4K at 120 Hz, while the gigabit Ethernet port replaces wireless for lower latency. Three USB 3.0 ports free the handheld's own port for charging only. A 100 W charger is recommended for full Turbo Mode power on ROG Ally.

Included capabilities

The dock supplies HDMI 2.1 4K@120 Hz output, three USB 3.0 ports and gigabit Ethernet without extra adapters. It delivers up to 100 W PD charging so the handheld stays powered during long sessions. ROG XBOX Ally and XBOX Ally X are not supported, so buyers needing compatibility with those models must choose a different solution.

Questions about this item

Does the HDMI 2.1 port maintain 4K@120Hz during long sessions?

The dock outputs 4K at 120 Hz via HDMI 2.1. Sustained performance depends on the handheld's own thermal limits and the cable quality used.

How hot or loud does the HB0603 get when used all day?

The unit has no fan, so it runs silently. Heat stays low because it only passes through power and data; the handheld handles its own cooling.

Which charger must I already own to reach 100W PD charging?

A USB-C power adapter rated for 100 W is required. The dock passes up to 100 W through to the handheld, so the brick determines the actual charge speed.
