ST-YP-21 Type-C Dual-Port Audio & Charging Adapter Cable (Braided Edition)

Product Name: ST-YP-21 Type-C Dual-Port Audio & Charging Adapter Cable (Braided Edition)

Product Description:

The ST-YP-21 is an innovatively designed Type-C dual-port audio and charging adapter cable. Featuring a “one-cable, dual-interface” architecture, it intelligently integrates audio transmission and charging functions into a compact design. Crafted for modern Type-C interface devices, it allows users to enjoy high-fidelity audio while enabling fast charging—effectively addressing the common limitation of single-port devices that cannot handle audio and power simultaneously. This makes it an ideal solution for mobile entertainment and efficient workflows.

Dual-Port Design, Audio and Power Simultaneously:

• Audio and Charging in Parallel: One end connects to the device’s Type-C port, while the other extends into separate Type-C audio and Type-C charging ports. It supports calling, music playback, remote control, and fast charging all at once—no need to constantly plug and unplug cables.

• Full-Featured Audio Support: Connect headphones or external audio devices via the Type-C audio port to enjoy clear calls, immersive music, and convenient playback control—including play/pause, track skipping, and volume adjustment—using the built-in remote.

• Convenient Charging Expansion: The Type-C charging port supports various fast-charging protocols such as PD/QC. Simply connect a charger or power bank to quickly replenish your device’s battery, ensuring uninterrupted use.

Precision Craftsmanship, Efficient and Durable:

• Seamless Metal Housing: Constructed from high-strength aluminum alloy with a fine sandblasted and oxidized finish, it offers excellent scratch and rust resistance along with superior heat dissipation, ensuring stable performance even during prolonged high-load use.

• High-Density Braided Cable: The cable is wrapped in a black and gray interwoven braided layer, significantly enhancing tensile strength, bend resistance, and tangle resistance—maintaining durability through daily commutes and frequent plugging/unplugging.

• Independent Signal Shielding Design: Internally, it utilizes high-quality (16/0.08 enameled wire+250D)*4C wiring. The audio and power channels are independently isolated to effectively prevent signal interference, ensuring pure sound quality and stable, efficient charging.

Compact and Smart, Ready to Go Anywhere:

• Portable and Space-Saving: With a total length of just 0.12 meters, it is lightweight and compact—easy to carry in a bag or pocket, and perfect for travel, office use, in-car setups, and more.

• Understated Dual-Tone Design: Available in a sleek black and gray interwoven style, offering a versatile and professional look that blends naturally with a wide range of devices.

Ideal Use Cases:

• Gaming on your phone while listening to audio and charging simultaneously.

• Watching movies during long trips while keeping your device powered.

• Joining video conferences while maintaining device battery life.

• Connecting to car audio and using a car charger on the go.

In Summary:

The ST-YP-21 Type-C dual-port audio and charging adapter cable redefines the expansion experience for Type-C devices with its innovative dual-port design, robust metal construction, and intelligent audio-power separation architecture. Whether you’re an immersive gamer, a frequent traveler in need of lasting battery life, or a multitasking professional, it delivers reliable support for simultaneous audio and charging—freeing you from port limitations and letting you efficiently enjoy both sound and power.
