Frequently Asked Questions

Can this cable charge a MacBook Pro 16" at full 140W or 240W?
Yes. This cable supports PD 3.1 up to 240W (48V/5A), which covers the full charging speed of MacBook Pro 14" (96W) and MacBook Pro 16" (140W), as well as high-power Windows laptops up to 240W.

Does this cable support 8K video output?
Yes. When connected between two Thunderbolt 4 or USB4 devices, it supports single 8K/30Hz or dual 4K/60Hz display output. Video output requires both the host device and monitor to support Thunderbolt 4 or USB4 DisplayPort Alt Mode.

What is the difference between Thunderbolt 4 and USB4?
Thunderbolt 4 is Intel's certified implementation of USB4 Gen 3, guaranteeing 40Gbps data, 240W power, and 8K video. USB4 Gen 3 offers the same bandwidth but certification requirements vary by manufacturer. This cable is certified for both.

Is an E-Mark chip required for 240W charging?
Yes. USB-C cables rated above 60W must include an E-Mark chip to safely negotiate higher voltages. This SlimQ® cable includes an E-Mark chip, enabling safe 48V/5A (240W) power delivery.

Is this cable compatible with USB-C docking stations?
Yes. It is compatible with Thunderbolt 4 and USB4 docking stations, including models from CalDigit, OWC, Belkin, and others. It also works with USB 3.2 and standard USB-C docks at their respective speeds.
