This is our solution. We will have some iPhone 13s that still use lightning cables, many sets of Bluetooth earbuds that have USB-A to USB-C cables (some that are built into the cradle so no way to swap), a tablet the kids use that still has micro USB charging, sofa with integrated USB-A ports, and a car with integrated USB-A port. So we will need a mix of USB-A and USB-C charger blocks, 3-4 different styles of cables, and some adapters to bridge the gap on items that aren't replaced regularly. I literally have a "hardware" box in my cabinet with all the different cables and charger blocks grouped together. Otherwise we have charging accessories everywhere.USB-A to USB-C adapters are readily available on Amazon and eBay for roughly 99¢ each. It could make sense to buy a few today, as a lot equipment has USB-A ports (cars, computers, routers, etc), but a lot of new gear is USB-C.
Wonder how many people that installed the USB-A port outlets on their walls will be running out to find updated versions.
