How to use

Connect one USB-C end of the cable to your host device (laptop, charger or docking station) and the other end to the target USB-C device. The E-mark chip automatically negotiates voltage and current for compatible devices; ensure both connected devices support the intended power and data modes. For maximum data speed and charging power, use with hosts and devices that support USB4 Gen 2x2 and Power Delivery profiles.

Recommendations

For safe operation, avoid bending the cable sharply near the connectors, keep it away from liquids and excessive heat, and use chargers and devices that comply with USB Power Delivery standards. Short length and flat design are intended for portable connections rather than long-distance routing.
