Define "regular USB cable".

Which ends are on this regular USB cable? micro USB? mini USB? USB-B?

I honestly have far more lightning cables lying around than I do mini USB or micro USB. I don't own many devices that use either micro or mini USB. Lightning also made sense because it was a solid connection, that did not wear out quickly, insertion and removal had no chance of damaging anything whereas I have had several mini and micro USB boards that I've created myself where I've had to replace the connectors over time.
