The letters correspond to the physical connector. The rectangle one everyone knows is A, B is the square connector usually used with printers and other accessories. C is a small, oval connector, and the first one that can be plugged in “upside down” because it’s symmetrical.
C is now common on phones and tablets and other smaller devices. If the connector is ovalish but even smaller and weirdly shaped, that’s one of the mini/micro USB variants and you need to find the right cable to match.
(If you have a USB C cable and i won’t fit into the oval connector because it’s too big, that’s Lightning made by Apple before C existed and is only found on their devices. You have to get a cable with Lightning on at least one end.)
How do you know if the cable is a C type of USB?
You look at the ends that plug into stuff
Oh do they have the letter printed on it?
No? Ok thanks.
No, but they’re very visually distinct from USB-A, USB-B, Mini USB, and Micro USB.
