I have this small and slim cable adapter kit that has a USB-C cable with USB-C to Micro USB, USB-C to the old Iphone plug, USB-C to USB-A, and USB-A to USB-C. It wven comes with one of those pins for opening the SIM card tray.

Combined with my USB-C charging block I can charge nearly any device I come across. I got this specifically so if someone was out of luck I could offer them my charger. I work at a school so this is a frequent enough occurrence.
