Just did a quick count up most of fhe power sockets in my house also have usb power links (make that about 20 charging ports) the computers between them have about 18 USB ports and I have about 5 chargers.
Now as to usb cables, well there are some that charge devices, some the work for data, and a few (usually misplaced) which can reliably do both, and that is before you get to the disaster zone called usb c.....
Anyway do I need more chargers probably not.
