What Buyers Say
This JSAUX dock is a bit of a mixed bag, with many users loving its ability to turn their handheld into a desktop gaming rig, but a noticeable number running into frustrating display and audio quirks. The 4K@120Hz HDMI output is a big draw, but it doesn't always play nice with every monitor, sometimes getting stuck at lower resolutions or needing an EDID emulator to even work. The Gigabit Ethernet and 100W PD charging are consistently praised for their performance, keeping games smooth and devices powered. However, the lack of an included power brick means you're buying another accessory to get the most out of it.
“Dude, this dock is sick for my Steam Deck, 4K@120Hz actually works on my TV and games look so much better, but seriously, why doesn't the sound always come through the TV? It's annoying having to mess with it.”
Common Praise

Ownership Tips

Buying Guide
When you're looking at a docking station for your handheld gaming PC, you're basically turning it into a mini-desktop. You need to think about what you'll connect: a monitor, a keyboard, a mouse, maybe an external hard drive. The dock's job is to give you all those ports and make sure your handheld stays charged while doing it. Don't forget that the dock itself usually needs power, so you'll need a separate wall charger.
