TelDaykemei USB4 40Gbps Cable

This 0.5 metre USB Type-C to Type-C cable delivers up to 40Gbps data transfer and 240W power delivery for compatible laptops, phones and accessories. It meets the USB 4.0 specification and works with Thunderbolt 4 hosts for high-speed workflows. The nylon-braided jacket and aluminium alloy shell protect the conductors during daily use.

Thermals noise and power draw

The integrated E-Marker chip negotiates power up to 48V 5A and manages heat during charging sessions. Aluminium alloy shells provide thermal insulation so the cable stays cool to the touch at 240W. No active cooling is present, so operation remains silent in normal use.

Sustained load behaviour

Rated for more than 30,000 bend cycles at 180 degrees, the cable maintains stable signal transmission during prolonged 40Gbps transfers. It drives one 8K or 5K display at 60Hz or two 4K displays at 60Hz when the host supports DisplayPort Alternate Mode. Backward compatibility covers 200W, 140W, 100W, 60W and 18W devices.

Questions about this item

How do I connect the USB-C ends for 40Gbps data and 240W charging?

Plug each USB-C connector firmly into a port that supports USB4 40Gbps and 48V 5A power delivery; the built-in E-Marker chip negotiates the highest rate automatically, but the link will fall back if either device lacks 40Gbps or 240W capability.

When will the nylon-weave jacket or connectors need replacement?

The cable is rated for over 30,000 180-degree bend cycles; inspect the strain reliefs periodically and replace the cable if the weave frays or a connector becomes loose.

What limits sustained 40Gbps throughput or 240W charging first?

Thermal throttling in the host or device typically caps prolonged 40Gbps transfers or 240W charging before the 0.5 m cable reaches its electrical limits.
