Purpose and users
This USB-C to USB-C cable delivers up to 100W of power for charging laptops, tablets and phones that accept USB Power Delivery. It is aimed at owners of devices such as the MacBook Pro 16-inch, iPad Pro models from 2018 onward, Galaxy S22 Ultra and similar USB-C hardware. The cable does not support video output, so it cannot drive an external monitor.
Thermals, noise and power
An integrated E-marker chip with a 56K ohm resistor regulates the 20V/5A connection to stabilise voltage and current during fast charging. The 100W rating allows a MacBook Pro 16-inch to reach 38% charge in 30 minutes, which is 58% faster than a 60W alternative. Data transfers run at 480Mbps over the USB 2.0 interface. No active cooling or moving parts are present, so the cable operates silently.
Build and daily use
Zinc-alloy connectors and a nylon-braided jacket are designed to withstand more than 35,000 bending cycles and provide ten times the tensile strength of ordinary cables. At 3.3 feet the length suits desk charging without excess slack, while the 6.6-foot variant offers extra reach. Compatibility covers PD 3.0, QC 4.0 and Samsung Fast Charging protocols across a wide range of phones, tablets, laptops and the Nintendo Switch.

Questions about this item
How do I connect this USB-C to USB-C cable for 100W charging?
Plug both ends into the USB-C ports on your 100W charger and device; the built-in E-marker chip and 56K ohm resistor handle power negotiation automatically.
When should I replace this 3.3 ft nylon braided cable?
Replace it if the zinc alloy connectors loosen or the braid frays; the joints are rated for 35,000+ bends, so heavy daily flexing is the first wear sign.
What speed limit appears first during sustained large-file transfers?
Data tops out at 480 Mbps USB 2.0 rates, so the cable itself is the bottleneck long before any device or charger limit is reached.
