No, not all usb c cables are equal. Even two USB C to C cable that look exactly the same are not necessarily exactly the same. Many sellers misrepresent charging and data transfer speeds to boost sales. At ByteCable, we offer durable USB C cables with accurately labeled parameters, ensuring you can use our cables reliably for business or industrial applications.

If there is no professional testing tools, you can roughly judge the transmission capability from its appearance. Generally speaking, the greater the data transmission capacity, the thicker the cable.
At present, a USB C cable supports up to 240W charging power, and you can test it with professional testing tools. Moreover, USB C cables that support more than 3A current may have built-in E-marker chips, which we cannot see from the appearance.
There are various kinds of USB C cables, such as jacket is made of TPE, PVC, Nylon braided, so not all USB C cables are the same.
