USB C to C cable for 240W charging

This 6.6 ft USB C to C cable delivers up to 240 W of power and 20 Gbps data transfer under the USB 3.2 Gen 2 standard. It supports 4K video output at 60 Hz and carries an E-Mark chip for safe high-wattage charging. The cable suits professionals who need a single cord for power, data and external displays.

Practical limits of USB 3.2 Gen 2 and PD 3.1

The 20 Gbps data rate and 240 W charging ceiling are fixed by the USB 3.2 Gen 2 and Power Delivery 3.1 specifications. Video output is limited to 4K at 60 Hz. Thunderbolt 3 hosts are supported, but the cable does not reach Thunderbolt 3 speeds or features. Length is fixed at 6.6 ft, so longer runs need a different cable.

240 W E-Mark rating decides fit

The 240 W E-Mark rating is the single specification that determines whether this cable matches a device's charging requirement. Buyers whose gear draws 240 W over USB-C need this rating; buyers whose devices only charge at lower wattages do not require it.

Questions about this item

Should I pick the 1.6ft, 3ft, 6.6ft or 10ft version of this cable?

Choose the length that matches the distance between your devices; the 6.6ft option gives desk-to-monitor reach while 1.6ft suits dock-to-laptop setups.

What does the 240W rating mean when I plug this into my laptop?

It delivers up to 48V at 5A under USB PD 3.1, so a 240W-capable laptop charges at full speed while lesser devices draw only what they support.

The cable is labelled USB 3.2 Gen 2 — what does that cap at in practice?

The 20Gbps data lane handles 4K 60Hz video and fast file transfers, and it is backward compatible with Thunderbolt 3 hosts.
