240W 20Gbps USB-C Cable

This USB-C to USB-C cable delivers up to 240 watts of power and 20 gigabits per second of data throughput. It carries an E-Mark chip and supports Power Delivery 3.1 alongside earlier PD and Quick Charge standards. The three-foot length suits desk and travel use. It connects laptops, tablets, phones and portable monitors with USB-C ports.

Build Integration

The male-to-male plug fits any host or peripheral with a USB-C receptacle, requiring no adapter or driver. It frees a single port to handle charging, 4K 60 Hz video and high-speed data simultaneously. Backward compatibility lets it negotiate lower power levels such as 100W, 60W or 15W automatically. Thunderbolt 3 hosts also accept the cable for dock or display chains.

Capacity and Headroom

The 240W rating covers the most demanding USB-C laptops and fast-charge phones, while 20Gbps bandwidth handles large media transfers and dual-display streams. Video output reaches 4K at 60 Hz with audio. The cable does not support Thunderbolt 4 or USB4 40Gbps speeds, so hosts needing that bandwidth will operate at the lower rate.

Questions about this item

Does the 20Gbps data rate hold up during long transfers or does it throttle?

The cable is rated for 20Gbps over USB 3.2 Gen 2 and carries an E-Mark chip for 240W PD3.1 power delivery, so the rated speed is maintained as long as both host and device support the same generation.

How warm does the cable get and is there any fan noise when it runs at 240W all day?

The cable has no active cooling and no fan; it relies on its conductors and insulation to handle 48V at 5A, so it will warm slightly under maximum load but produces no noise.

What must my laptop and monitor already have for the 4K@60Hz video to work over this cable?

Both ends need USB-C ports that support DisplayPort Alt Mode; the cable itself carries the video signal but does not add the capability.
