New 240w Usb 4.0 cable, 40 gbps data line for 8k high-definition monitor, Usb C to Usb C keychain fast charging cable

Ultra-Compact Keychain Portable Design with Protective Silicone Storage Case

This short USB4 Type-C cable adopts an innovative pocket-sized keychain structure, equipped with a detachable metal key ring and matching full silicone protective sleeve for easy daily carry. The total length of the flat cable is only 13.7cm, perfectly fitting into pockets, card packs and keychains without occupying extra space, solving the trouble of carrying long bulky charging cables for outdoor travel. The textured silicone outer shell delivers anti-slip, shockproof and scratch-resistant performance, fully wrapping the cable plugs to prevent gold-plated pins from wear, oxidation and dust contamination. Multiple solid color options including black, white and bright yellow are offered to match different personal accessories and daily carry styles.

Flagship USB4 Full-Spec Performance

Compliant with Thunderbolt 4 and USB4 Gen3 standard, this mini cable integrates three top-tier core functions in one slim cord. It supports peak 40Gbps ultra-high-speed data transfer, enabling fast bulk transmission of ProRes 4K/8K video, RAW camera files and large solid-state hard drive data without long waiting times. Built-in E-MARK intelligent chip supports 240W 5A high-power PD fast charging, quickly refilling gaming laptops, flagship smartphones and portable power banks. Meanwhile, it realizes lossless 8K@60Hz high-definition video signal output for external monitors, real-time camera monitoring and multi-screen office setup with zero picture lag and color distortion.

Body with Gold-Plated Anti-Oxidation Plug Terminals

The whole wire body is made of flexible textured flat silicone material, featuring excellent tensile strength, bending resistance and anti-tangling properties compared to round PVC cables. Thousands of repeated folds will not cause cracking, hardening or internal wire breakage, and the flat shape avoids messy knotting during storage. Both Type-C terminals adopt thick gold-plated metal pins to reduce transmission impedance and resist oxidation for stable long-term power and signal delivery. Reinforced strain relief joints at plug-wire junctions evenly disperse pulling force to protect fragile connection points, greatly extending the overall service life of this portable short charging and data cable.

Wide Cross-Device Compatibility for Photography, Office, Travel

This mini USB4 cable achieves ultra-wide universal compatibility with all mainstream Type-C interface digital devices, including Windows/Mac laptops, Android flagship phones, mirrorless cameras, portable SSDs and high-power power banks. It covers diversified daily usage scenarios: photographers use it for fast camera file backup and ProRes video recording; office staff rely on it for high-speed file transfer and multi-screen display; commuters and travelers hang it on keychains for emergency quick charging. The plug-and-play design requires no extra drivers, allowing one single tiny cable to complete charging, data sync and video expansion demands for all your portable electronics anytime anywhere.
