USB-C extension cable for charging and data

This two-pack provides 6.6 ft USB-C male-to-female cables that extend the reach of compatible devices. Each cable supports up to 100 W Power Delivery and 10 Gbps data transfer under the USB 3.2 standard. They also carry 4K video at 60 Hz for external displays.

Practical limits of USB 3.2 and Power Delivery

The 10 Gbps rate applies only when both host and peripheral support USB 3.2 Gen 2; older ports will fall back to slower speeds. Full 100 W charging requires a charger and device that both negotiate 20 V at 5 A through the built-in E-Marker chip. Video output works only over USB-C ports with DisplayPort Alt Mode.

What to verify before ordering

Confirm that your host port and the target device both use USB-C connectors and support the features you need — data, charging or video. Check that the combined cable length including this extender stays within the specification limits for reliable 10 Gbps operation. Ensure your power supply can deliver the wattage your device requires.
