You know you can get a lightning-to-C adapter for very little, right? Here you go, under $2 each: https://www.amazon.com/Lightning-Adapter-Charging-Transfer-C... (probably under $1 each if you have the patience to look for them in other sites)

And a lot of chargers don't have a cable built-in, they just have a USB-A or -C port - so it's just a matter of replacing the cable. But - again, if you'd rather not do even that, you're welcome to keep using your old cable with a USB-C converter
