JSAUX Double-Decker Case Powers Up Steam Deck

JSAUX is doubling down on the Steam Deck ecosystem with a fresh lineup of handheld accessories designed to extend usability and eliminate battery anxiety. As the Steam Deck approaches its fourth year on the market, performance demands from modern titles continue to push hardware limits. Rather than waiting for a next-generation device, JSAUX is focusing on practical upgrades for existing users who want longer play sessions and better overall protection.

The Double-Decker Travel Supply Case: A Mobile Power Hub

The highlight of this release is the Double-Decker Travel Supply Case, engineered as more than just a storage solution. It features a dual-layer structure: the upper compartment secures the Steam Deck, while the lower compartment houses a power bank, charger, HDMI cable, and other accessories. This separation keeps hardware organized and protected during travel.

What makes it stand out is its integrated charging system. The case includes a dual 90-degree USB-C to USB-C cable that routes internally, allowing users to charge the console while it remains inside the case. Paired with a compatible power bank, the Steam Deck is ready to go the moment it is taken out. Silicone-assisted cooling vents further support heat dissipation during charging or extended gaming sessions.

Obsidian AR Screen Protector: Clearer Visuals Outdoors

To enhance display clarity, JSAUX introduces the Obsidian AR Screen Protector. Built with nano-level PVD anti-reflective processing, it reduces glare while maintaining 95% light transmittance. This ensures that visuals remain vibrant even under direct sunlight.

An advanced AF coating helps minimize fingerprints and smudges, keeping the screen clean during long gaming sessions. For players who frequently use their Steam Deck outdoors or in bright environments, this accessory targets one of the most common usability complaints.

Crossbody Sling Bag for Everyday Carry

The new Crossbody Sling Bag combines urban styling with practical protection. Inside, dual compartments separate devices and accessories, while a padded pressure-relief strap improves comfort during commutes. An internal L-shaped support creates a thumbstick safe zone to help prevent stick drift caused by pressure during transport.

Compatibility extends beyond the Steam Deck, fitting devices such as the Nintendo Switch 2, ROG Ally, and other popular handheld consoles. It is positioned as a flexible travel solution for gamers who switch between platforms.

5-in-1 Docking Station for Desktop Performance

For users who want a hybrid experience, the 5-in-1 Docking Station transforms the Steam Deck into a desktop-like setup. It supports 4K at 60Hz video output and up to 100W Power Delivery fast charging. The integrated stand includes bottom ventilation to maintain stable operating temperatures during extended sessions.

According to JSAUX, the Double-Decker Travel Supply Case is available in a standard edition priced at $39.99, while a bundled Power Bank Kit version costs $85.99 and includes a 65W 20000mAh power bank. The broader accessory lineup is available now, giving Steam Deck owners a practical upgrade path without waiting for new hardware.
