The 6A Rating: Most cables only handle 2A or 3A. This cable is rated for 6 Amperes, which is what allows your phone to go from 0% to 100% in about 20 minutes.
HyperCharge Support: Only this cable (paired with a 120W brick) will show the "120W Max" or "HyperCharge" animation on your screen.
Built-in Safety: It has a special chip that talks to your phone to make sure it doesn't get too hot while charging at such high speeds.

To handle the heat of 120W, the genuine cable has specific hardware:
6A Marking: The cable usually has a small "6A" engraved on the plastic near the USB-C tip.
The Orange Core: Both the USB-A and USB-C connectors have a distinct bright orange plastic center.
Thickness: It is noticeably stiffer and thicker than the 33W cable you asked about earlier.
E-Marker Chip: It contains a "Smart Identification" chip. Without this chip, the phone will limit the power to 27W or 33W for safety reasons.
