Has anyone ever experience a melted usb cable? This one is a charging cable from a USB mouse plugged into a laptop.

Correction : plugged directly into a USB port built into a original Sony power supply brick. Original charging cable from Logitech , but still probably from china . Mouse had been working for years, purchased from Staples .Rechargeable battery non alkaline battery. Just recently started using this USB port.

A poorly built cable that wasn't even made for charging could do that. USB ports by spec are supposed to be current limited, but there are differences in current depending on USB generation. 2 vs 3 vs 3.1 cover a range from 500ma to 1.5 amps. If you have a cable built for the former (500ma) plugged into a supply and device built for the latter, 3x as much, and you have a poorly made connection in the cable, yea stuff happens.

The USB 'Power Delivery' spec goes up to 20 volts and 100 watts.

I'm guessing wrong cable, maybe jammed in because it didn't fit properly, and a short circuit.

100 watts is the USB C spec Unlikely someone would, or even could, use C on a regular USB port. They were designed to be incompatible.

You really think one of our treasured readers would be so (insert your own pejorative adjective here ___ )? I at least, give the OP a bit more credit than that. I've also seen the consequences of USB 2 for USB 3 devices - they never seemed to charge.
