240 W USB4 Thunderbolt 4 cable

This USB4 cable delivers up to 240 W (48 V/5 A) USB PD 3.1 power for fast charging laptops and monitors. It supports 40 Gbps data transfer and 8K@60 Hz or dual 4K@60 Hz video output. The 3.3 ft USB C to USB C link suits creative pros and power users who need one cable for charge, data and display.

Thermals noise and power draw

The cable handles 240 W charging with stable voltage to protect devices from overheating during sustained loads. Passive construction means no fan noise and zero added power draw beyond the connected devices. Actual transfer speed depends on host and peripheral support for USB 4.0 or Thunderbolt 4.

Build fit and compatibility

USB C to USB C connectors work with Thunderbolt 3 and Thunderbolt 4 hosts plus USB 3.2, 3.1 and 3.0 devices. Single-cable docking frees up ports by carrying power, 40 Gbps data and 8K or dual 4K video simultaneously. Not for buyers who need longer reach or legacy USB-A connectors without an adapter.

Questions about this item

How do I install the BUCIER USB4 Thunderbolt 4 cable and what is the step people often get wrong?

Plug the USB-C connectors firmly into both ports until they click; the common mistake is not pushing them in fully, which prevents the 240 W PD 3.1 handshake and 40 Gbps link from activating.

What maintenance or replacement will the BUCIER USB4 Thunderbolt 4 cable need later?

No scheduled maintenance is required; inspect the connectors periodically for debris or bent pins and replace the cable only if physical damage or intermittent 8K@60Hz signal loss appears.

What limit shows up first on the BUCIER USB4 Thunderbolt 4 cable under sustained use?

The 240 W (48 V/5 A) power ceiling is the first hard limit; if the host or device cannot sustain that PD 3.1 contract, charging or 40 Gbps throughput will throttle before the cable itself overheats.
