You got a great question, but some slightly off answers in the thread.

The key value of interest for USB-C cables is the current (amps) ratings. This will affect the power rating (watts) based upon the capability of the charger and the device being charged.

The default current rating for USB-C to USB-C cables is 3 Amps. Contrast this with, for example, USB-A to USB-C cables which are normally to be limited to 1.5 A.

By comparison,older USB-A typically maxed out at 2.4A, with many common Qualcomm quick charging standards maxing out at 2A. This is the reason USB-A to USB-C must signal a device to attempt to draw no more than 1.5A lest it attempt to draw 3A from a device only capable of 2A.

Now connecting a 3A rated USB-C cable to an appropriate charger and device could supply anything from 15W for plenty of phones (3A at 5V) to 25W (25W Super Fast Charging which operates at 11V with 2.25A). Of course, the same cable between a laptop and its charger would easily deliver 60W (20V at 3A).

Using a USB-A to USB-C cable can be more challenging (read: harder to get a fast charge) since USB-A chargers don't always support the wider range of voltage standards common among USB-C devices (such as the power delivery modes which range up to 20V or the Programmable Power Supply PPS modes associated with Super Fast Charging). In the best case USB-A to USB-C might deliver up to 18W even when restricted to 1.5A using certain Qualcomm QuickCharge modes (still common among Samsung phones). In the worst case USB-C to USB-A will limit you to less than 8W of charging at the default 5V profile(!).

Good luck!

According to the Q&A on BB's page, the usb-c to usb-c cable supports up to 100W.

I'm still using a dynex lightning cable from many years ago and it's going strong. Pretty surprising for a cheap cable.

Is there a specification (or a limitation) on how much volts/amps/watts these cables are typically good for?

E.g. charging phone is no brainer, but what about a car jump starter unit?
Just curious.

Yup, generally cheap cables like these tend to hide those information.

My educated guess is that this should not go over 30 or 45 watts considering how thin the cables are.
