As USB-C becomes the standard for charging and data transfer, users often find a wide range of prices when shopping for USB-C cables. Some are available for just a few dollars, while other\u00a0which\u00a0marketed as USB-C fast charging laptop cables\u00a0or Thunderbolt 4 USB-C cables\u2014can cost significantly more. So, what justifies these price differences?
