USB-C 3.2 Gen 2×2 cable delivers 20 Gbps data, 240 W PD 3.1 charging and 4K 60 Hz video in a one-metre length

Cable Length 1m

  • 240W PD 3.1 fast charging with E-Mark chip protection
  • 20Gbps USB 3.2 Gen 2x2 data transfer speed
  • 4K@60Hz video and audio output to external displays
  • Thunderbolt 3 and 4 compatible for versatile connectivity
  • Backward compatible with PD 3.0, QC 3.0 and Samsung adaptive charging

What this cable does

The BUCIER USB C cable carries data at up to 20 Gbps, delivers up to 240 W of power with PD 3.1 and QC 4.0, and drives 4K displays at 60 Hz. An integrated E-Mark chip manages the high-power handshake and protects connected devices during charging. It is built for users who need one cable to handle fast charging, high-speed file transfers and external monitor output.

How the E-Mark chip changes use

The E-Mark chip enables the cable to negotiate 50 V at 5 A safely, so it works with 240 W adapters as well as lower-power bricks down to 15 W. Backward compatibility with PD 3.0, PD 2.0, QC 3.0, QC 2.0 and Samsung adaptive fast charging means older chargers still function, just at their rated speeds. Without the chip, many high-wattage adapters would fall back to lower power or refuse to charge.

What to verify on your devices

Confirm that both the host and the display have USB-C ports supporting video output and input respectively, otherwise the 4K@60 Hz link will not activate. Check that your power adapter is rated for the wattage you intend to draw; the cable alone does not increase the adapter's maximum output. The cable is one metre long, so measure the distance between your devices to ensure the reach is sufficient.

Questions about this item

Will the E-Marker chip or 5 A current rating degrade over time and require cable replacement?

The integrated E-Marker chip manages PD 3.1 negotiation up to 50 V / 5 A and is backward compatible with PD 3.0, PD 2.0, QC 4.0, QC 3.0 and Samsung adaptive fast charging, so the cable continues to regulate power safely without a scheduled replacement interval.

What limits sustained 20 Gbps data transfers or 240 W charging during all-day use?

The cable is rated for USB 3.2 Gen 2×2 at 20 Gbps and PD 3.1 at 240 W; the practical limit will be the host port, charger or device thermal throttle rather than the cable itself.

Does the cable get noticeably warm or draw extra power when running 4K 60 Hz video and 240 W charging together?

The E-Marker chip negotiates PD 3.1 up to 50 V / 5 A and the cable supports 4K 60 Hz video; any warmth depends on the charger and device load, not on additional cable electronics.
