Vszerda 16K Thunderbolt 5 Cable 6.6ft 80Gbps 240W PD3.1

SKU CH-W11T-6KVJJ

Transmits 80 Gbps data and delivers 240 W power over 6.6 ft with 16 K 60 Hz video support

  • 80 Gbps bi-directional bandwidth for fast data transfers with USB4 Gen 3x2 devices
  • 240 W power delivery charges laptops and phones at full speed using PD 3.1 EPR
  • 16 K at 60 Hz or dual 8 K at 60 Hz display output via DisplayPort 2.1
  • Bandwidth Boost up to 120 Gbps enhances high-refresh-rate monitor performance
  • Backwards compatible with Thunderbolt 4, Thunderbolt 3 and USB 3.2 devices

Cable purpose and compatibility

This 6.6 ft Thunderbolt cable supports USB4 Gen 3x2 and is fully backward compatible with Thunderbolt 4, Thunderbolt 3, USB 3.2 and USB 2.0 devices. It suits creators, gamers and professionals who need a single bi-directional link for power, data and video. Buyers who require longer runs or optical isolation will need a different solution.

Power delivery and thermals

The cable handles up to 240 W at 48 V under PD 3.1 Extended Power Range and negotiates lower profiles such as 140 W, 100 W and 60 W automatically. It also supports QC 4.0, PPS, AFC, SCP and FCP fast-charge standards. No active cooling is required during normal charging or data use.

Sustained load behaviour

Bandwidth Boost enables up to 120 Gbps for display traffic while maintaining 80 Gbps bi-directional data throughput. The link drives dual 8K or 6K at 60 Hz, triple 4K at 144 Hz or a single 4K panel at 540 Hz without signal degradation over the full length.

Questions about this item

How do I connect the USB C Male to USB C Male ends so the cable works bi-directionally?

Align the reversible USB C Male connectors with the ports on both devices and insert until they click; the bi‑directional design means either end can go to the host or the peripheral without flipping the cable.

Will the PD 3.1 Extended Power Range circuitry need replacement after repeated 240W charging cycles?

The cable is built to the PD 3.1 EPR specification and rated for 240W at 48V; no user‑serviceable parts are inside, so it does not require scheduled replacement under normal use.

At what point does the 80Gbps bi‑directional bandwidth limit appear during a sustained large file transfer?

The 80Gbps ceiling is the maximum bi‑directional rate with USB4 Gen3x2 devices; sustained transfers will hit this limit first before any Bandwidth Boost to 120Gbps can be utilised for display traffic.
