As the Steam Deck nears its fourth year, it remains a favorite for millions. However, as titles become more demanding, long-term users are increasingly feeling the limits of their hardware’s original battery endurance and display clarity.
Having supported the Steam Deck community from the very beginning, JSAUX is stepping up to help players keep their gear at peak performance. This latest effort is highlighted by the debut of the Double-Decker Travel Supply Case, alongside the new Obsidian AR Screen Protector, Crossbody Sling Bag, and 5-in-1 Docking Station.
“Like many players, we were anticipating a Steam Deck 2. Since that wait continues, it felt like the right time to focus on the upgrades current owners need most,” said the Head of Product Marketing at JSAUX.
The Hub for Extended Play: Double-Decker Travel Supply Case
Serving as the undisputed star of the new collection, the Double-Decker Travel Supply Case is far more than just a place to store your console. It’s a mobile power station designed to breathe new life into veteran handhelds by tackling battery anxiety head-on.
- Double-Decker Storage System: The upper layer securely fits the Steam Deck, while the lower layer stores a power bank, charger, HDMI cable, and accessories- keeping the console and accessories separated and protected.
- Charge Inside the Case, Ready to Play: The lower compartment holds a power bank (not included), and the included dual 90° USB-C to USB-C cable is routed inside the case to charge your Steam Deck directly. Take it out and play instantly.
- Assisted Cooling Vent Design: External silicone vents provide heat dissipation assistance during charging or high-load gaming, reducing heat buildup and helping maintain stable performance during extended play.
Refining the Complete Handheld Experience
To complete the latest hardware refresh, JSAUX is also introducing specialized tools for visual protection, urban commuting, and high-performance docking.
The Obsidian AR Screen Protector for Steam Deck is a pro-grade upgrade that stops screen glare. It uses a nano-level PVD AR process to cut reflections while maintaining a high 95% light transmittance, ensuring the display stays vibrant even in direct sunlight. Its advanced AF coating further ensures a pristine, fingerprint-resistant display during long gaming sessions.
The Crossbody Sling Bag combines sleek urban style with rugged protection. Dual compartments and a padded, pressure-relief strap make every commute comfortable. Inside, an L-shaped support creates a “safe zone” for thumbsticks to prevent stick drift. It’s built for wide compatibility, perfectly fitting the Nintendo Switch 2, Steam Deck, ROG Ally, and most popular handheld consoles.
The 5-in-1 Docking Station is designed for Steam Deck and is also compatible with devices like the ROG Ally and Legion Go. It enables a high-performance desktop setup with 4K@60Hz video output and 100W PD fast charging. The integrated stand features bottom vents to maximize airflow and maintain optimal temperatures during extended use.
