Frequently Asked Questions

Q: Is this USB4 cable compatible with Thunderbolt 4 devices?

A: Yes! This cable is fully compatible with Thunderbolt 4 devices, supporting the same 40Gbps bidirectional bandwidth (up to 80Gbps USB4 spec) and PD 240W charging, making it ideal for MacBooks, Dell XPS, and other Thunderbolt 4-enabled laptops and peripherals.

Q: Can I use this cable for 8K video output on my monitor?

A: Absolutely. The cable supports 8K @ 60Hz via HDTV 2.1 compatibility. Both your source device (e.g., laptop or GPU) and the display must support 8K output via USB-C/Thunderbolt 4 for this resolution to be achieved.

Q: Does the 13cm length limit which devices I can use it with?

A: The 13.7cm (5.4 inch) length is intentionally compact — ideal for tethered setups like laptop-to-power-bank, desktop cable chains, or side-by-side device connections. For longer-distance connections, a standard-length USB4 cable would be recommended.

Q: What does the E-Marker chip do?

A: The built-in E-Marker chip communicates power and data capabilities between your devices, enabling safe 240W power delivery and full USB4 80Gbps data speeds. Without an E-Marker, cables are limited to lower wattage and speed — so this chip is essential for top performance.
