Handheld gaming PCs like the Steam Deck OLED, ROG Ally X, Legion Go, and MSI Claw are incredibly powerful—but the experience truly changes when you connect them to a big screen. That’s where the JSAUX Upgraded Docking Station 4K@120Hz (HB0603) steps in.
This dock has quickly become popular because it delivers HDMI 2.1 with 4K@120Hz, 100W fast charging, and rock-solid connectivity—all at a surprisingly affordable price. With over 4,300+ reviews, an Amazon’s Choice badge, and 5,000+ monthly purchases, it’s clearly trending among handheld gamers who want a console-like setup without overspending.
Whether you’re gaming at home, setting up a portable workstation, or building a minimalist desk, this dock promises excellent value for money.
Key Features & Specifications
Here’s what makes the JSAUX 6-in-1 Dock stand out from generic Steam Deck docks:
- HDMI 2.1 with 4K@120Hz output for ultra-smooth gameplay and media
- 100W Power Delivery charging to keep your device running in Turbo mode
- 3 × USB 3.0 ports for controllers, keyboard, mouse, or external storage
- Gigabit Ethernet port for low-latency online gaming
- Wide compatibility with Steam Deck LCD/OLED, ROG Ally / Ally X, Legion Go / Go S, and MSI Claw

At just 170 grams, it’s lightweight but solid—ideal for both permanent setups and travel gaming stations.
Performance & Real-World User Experience
Gaming on a Big Screen
The biggest upgrade here is clearly 4K@120Hz via HDMI 2.1. If you’re coming from older 4K@60Hz docks, the difference is immediately noticeable—especially in fast-paced games like shooters, racing titles, or action RPGs.
On a 120Hz monitor or TV:
- Gameplay feels smoother
- Input latency is noticeably reduced
- Screen tearing is minimized
Even cinematic games look sharper and more fluid during cut-scenes.
Charging & Stability
The 100W PD charging support is a big deal. While the Steam Deck itself doesn’t draw the full 100W, this ensures:
- Stable power delivery
- No battery drain during heavy gaming
- Consistent performance in docked mode
This is especially useful if you’re running the Steam Deck OLED or ROG Ally X at higher performance profiles.
Daily Desk & Productivity Use
Beyond gaming, this dock works surprisingly well as a mini workstation hub. Plug in a keyboard, mouse, external SSD, and Ethernet cable—and your handheld instantly feels like a desktop PC.
This setup pairs well with tech workflows similar to what we discussed in our Amazon Fire HD 10 Tablet Review on ForageQuill, where portability meets productivity:
