Handheld Docking Station with 4K@120Hz

The Belkin CH4504 is a 6-in-1 docking station built for Valve Steam Deck, ASUS ROG Ally, Lenovo Legion Go and MSI Claw handhelds. It adds an HDMI 2.1 video output, Gigabit Ethernet, three USB 3.0 Type-A ports and 100W Power Delivery pass-through charging in a single compact hub. The package includes a 65W USB-C charger with US, EU and UK plug adapters and a 6.6ft cable.

HDMI 2.1 Bandwidth and Monitor Requirements

The HDMI 2.1 port can drive 4K at 120Hz, 5K at 30Hz, 2K at 144Hz or 1080p at 240Hz, but only when the handheld itself supports those modes and an HDMI 2.1 certified cable is used. Without external power connected to the dock, video output and downstream ports are disabled, so the supplied charger or another PD source must remain plugged in during use.

Power Delivery Headroom and Device Limits

The dock accepts up to 100W PD input and passes full power to the handheld, covering the ROG Ally 30W Turbo Mode and Steam Deck charging needs. The bundled 65W charger is sufficient for most handhelds but cannot deliver the maximum 100W the dock can pass through. The hub is not compatible with ROG Xbox Ally or Xbox Ally X 2025 models, nor with Nintendo Switch consoles.

Questions about this item

Should I pick the 65 W charger bundle or a 100 W one for Turbo Mode on the ROG Ally?

The bundle includes a 65 W charger; the dock accepts up to 100 W PD input, so a 100 W adapter is recommended for full Turbo Mode power.

What does the 4K 120 Hz HDMI 2.1 label mean when I hook up my monitor?

It supports 3840×2160 at 120 Hz if your handheld and cable are HDMI 2.1 capable; otherwise it falls back to 60 Hz or 30 Hz.

Does the Gigabit Ethernet port actually deliver 1 Gbps speeds in practice?

The port is rated for Gigabit Ethernet; real-world throughput will approach 1 Gbps with a Cat 5e or better cable and a compatible router.
