Questions about this item

Does the 40Gbps bandwidth hold steady during long file transfers?

The cable is built to the Thunderbolt 4 standard with multi-layer shielding, so the 40Gbps data rate is maintained during sustained use.

How much heat or noise does the cable produce when delivering 240W all day?

A passive cable generates no noise and negligible heat; the 240W PD3.1 rating means it handles continuous high-power charging without thermal issues.

What port must my device already have for this extension to work?

Your device needs a USB-C port that supports Thunderbolt 4 or USB4 to get the full 40Gbps, 240W and 8K@60Hz capability.
