FAQ

Does a fast charging cable also mean fast data? Not usually. Many USB-C cables charge at high wattage but move data at USB 2.0 speed, which is 480Mbps. This cable is rated for both, so it will not be the bottleneck when you copy from an external SSD.

What does the e-marker chip do? It identifies the cable to the charger and the device, telling them what it can safely carry. With it, the two ends negotiate the full 100W. Without one, a charger has no way to confirm the cable's capability and falls back to a slow trickle to stay safe.

Do I need the 100W rating if I only charge a phone? No harm in it. The charger and device settle on what the device wants, so a phone draws phone wattage. The rating matters the day you plug in a laptop.
