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.
USB C is compatible with all USB data transfer protocols: USB 2.0, USB 3.0, USB 3.1, USB4, Thunderbolt 3, Thunderbolt 4, Thunderbolt 5, You can only know the data transmission rate through a professional tester.
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.
Even if two USB C cables look the same and have the same data transfer rate and charging power, they may not be the same, for example some USB C connectors are nickel plated, some are gold plated, and some cord have 3 layers of Shielding, and some have 2 layers.
