These are unusual connectors, but when you need them, you need them. I have several USB hard drive enclosures with a USA Type-A 3.0 connector instead of USB-C or USB Micro Type-A. I didn't have any spare parts. So if someone decides to go into hiding, you can use the drive. I bought them as spares and they work great. Now I leave one of those cables at work and not worry about not being able to connect my drive.
