Cable Leader 6.6ft (2m) USB4 Cable 20Gbps, USB-C to USB-C Gen 2x2 Data Cable, 240W PD 3.1 Fast Charging, 4K Video, E-Marker, Black - for MacBook, Laptop, Docking Station & Portable SSD

USB4 speed with full-power charging. This 6.6 ft (2m) Cable Leader USB4 cable is rated Gen 2x2 - a 20 Gbps link, double a standard 10Gbps cable and four times a USB 3.0 cord.

The charging side is where it really separates from ordinary cables: 240W USB Power Delivery 3.1, versus the 100W ceiling that most USB-C cables were built for. High-performance laptops draw more than 100W, and with a 240W cable one cord handles charging, data and video at once.

Video runs to 4K through DisplayPort Alt Mode on devices that support it, so a single cable can drive an external display from a laptop.

Both connectors carry an E-Marker chip that reports the cable's certified ratings to every connected device - required for high-wattage charging and full-rate data.

Use it with portable SSDs, docking stations, external monitors, and modern USB-C laptops and tablets.

Frequently Asked Questions

Q: How is this different from a 10Gbps USB-C cable?
A: It carries 20 Gbps instead of 10, and 240W of charging instead of 60 or 100W.

Q: Do I need a USB4 port?
A: The cable is backward compatible with slower USB-C ports; the full 20 Gbps applies between USB4-capable devices.

Q: Will it charge my laptop at full speed?
A: Up to 240W, which covers nearly every USB-C laptop including high-performance models.

Q: What does the E-Marker chip do?
A: It identifies the cable's certified current and data ratings to both devices, which is required for safe high-wattage charging.

Q: Should I pick this or the 40Gbps version?
A: Choose 40Gbps if you drive 8K displays or NVMe enclosures that can saturate it; 20Gbps is ample for portable SSDs, docks and 4K displays. Backed by Cable Leader's Lifetime Warranty and US-based support. Ships from Chino, California.
