As the Steam Deck approaches its fourth year on the market, Valve’s handheld remains a fan favorite. However, as modern titles become increasingly demanding, long-term users are starting to feel the limits of the hardware’s original battery endurance and display clarity. To address these concerns, accessory manufacturer JSAUX has unveiled a new collection of gear, spearheaded by the Double-Decker Travel Supply Case.
A Mobile Power Hub: Double-Decker Travel Supply Case
The main product of this new lineup is the Double-Decker Travel Supply Case, designed specifically to act as a mobile power station. Unlike standard carrying cases, it features a dual-layer storage system: the upper compartment securely holds the Steam Deck, while the lower layer is dedicated to storing a power bank, charger, and other essential accessories.
One of its most practical features is the “Charge Inside” design. Using an included dual 90° USB-C cable, players can charge their console while it remains protected inside the case. To prevent overheating during charging or high-load gaming, the case includes external silicone vents that assist with heat dissipation, ensuring stable performance for extended sessions.
Refining the Handheld Experience
Beyond the carrying case, JSAUX has introduced three additional accessories to enhance the overall experience for handheld gamers:
- Obsidian AR Screen Protector: This screen protector utilizes a nano-level PVD AR process to reduce reflections by up to 95%. It ensures that the display remains vibrant and visible even in direct sunlight while providing a fingerprint-resistant coating.
- Crossbody Sling Bag: Designed for urban commuters, this bag features an L-shaped internal support structure to protect thumbsticks from drift. It is compatible with a wide range of devices, including the Steam Deck, ROG Ally, and even the Nintendo Switch 2.
- 5-in-1 Docking Station: A high-performance desktop solution that supports 4K@60Hz video output and 100W PD fast charging, featuring an integrated stand with bottom vents for maximum airflow.
The Double-Decker Travel Supply Case is available now for $39.99, or as part of a Power Bank Kit for $85.99, which includes a high-capacity 65W 20,000mAh power bank.
