JSAUX 6-in-1 Docking Station for ROG Ally X and Steam Deck - 4K HDMI

In this review the JSAUX 6-in-1 Docking Station is examined as a compact hub for handheld gaming consoles like the ROG Ally X, ROG Ally, Steam Deck and Legion Go. The biggest reason to consider it is practical versatility: it combines 4K@120Hz HDMI output, gigabit Ethernet and multiple high-speed USB ports with 100W PD charging in a small, modular package that doubles as a stand. For players who want a tidy desktop setup without carrying a full docking tower, this dock aims to bridge portable and home play.

Key Features

• 4K HDMI: Allows a direct HDMI output up to 4K@120Hz or 1080@240Hz for connecting to high refresh rate displays and TVs for crisp gaming visuals.
• High-speed ports: Offers one USB C 3.2 Gen 1 and two USB A 3.2 Gen 1 ports at 5Gbps for controllers, storage and peripherals.
• Wired network: Built-in Gigabit Ethernet provides a stable 1000 Mbps connection for multiplayer and downloads where Wi-Fi is unreliable.
• Power delivery: Supports up to 100W PD input so handhelds can charge at full speed when paired with an adequate charger.
• Modular stand: The base detaches so the unit can function either as a dock or as a compact stand, and an extra silicone pad improves grip and fit.
• Customizable cover: A removable front cover accepts a DIY card for personalization without tools.

Who It's For

The dock is best for handheld gamers who use their ROG Ally X, ROG Ally, Steam Deck or Legion Go both on the go and at a desk, and who want a small, multiport hub that supports high refresh or high resolution HDMI and wired networking. Streamers or competitive players who need low latency and stable ethernet will appreciate the gigabit port and high refresh video output.

It is less suitable for users who require a larger base for heavier cases or very thick protective shells beyond the supported 3 mm, or for buyers who need guaranteed flawless HDMI and charging performance without testing - some users report intermittent HDMI or charging issues and may prefer a different model with confirmed compatibility for their exact console and cable setup.
