That has nothing to do with the voltage/current inside the cable. You can't feel 48V on dry skin.

- lxgr 3y agoThis is assuming that only 48 V (relative to ground) were present on the cable. There are many ways in which low quality power supplies can expose up to full main power voltage on the secondary side. For example, with 230 V on Vbus and 225 V on "ground", an USB device might not even be able to tell the difference.
