Cable purpose and audience
This Thunderbolt 4 cable connects USB-C devices such as laptops, phones, hubs and docking stations. It supports up to 100W power delivery, 40Gbps data transfer and 8K video output for users who need a single cord for charging, fast file moves and high-resolution external displays.
Upgrade context
It replaces slower USB-C cables limited to 20Gbps or lower power delivery, making the jump worthwhile when a device supports 40Gbps Gen3 speeds, 100W charging or single 8K at 60Hz and dual 4K at 60Hz video. The 1.6FT length suits desktop setups where the host and peripheral sit close together.
Fit and alternatives
Suits owners of Thunderbolt 3 or 4 laptops, recent MacBook Pro models from 2018 to 2020, XPS, Chromebook and Samsung Galaxy S20 through S23 Ultra phones that accept 100W charging and 8K output. Buyers who need a longer reach, legacy USB-A connectors or cables rated for higher wattage should look at other options.

Questions about this item
What length is the cable so I know if it reaches my dock?
The cable measures 1.6 ft from end to end, giving a short reach for desk-mounted docks or monitors.
How do I get the full 40 Gbps speed instead of 20 Gbps?
Plug both ends into USB4 or Thunderbolt Gen3 ports; Gen2 ports limit the link to 20 Gbps.
When should I replace the cable to keep 100 W charging reliable?
Replace it if the connectors feel loose, the jacket shows kinks, or charging drops below the device’s rated speed.
