what do I neeed in order to plug my USB C to Lightning Cable into an outlet?

you can get an ac charger with usb-c connector

you can connect it and charge from a computer with an usb-c connector

you can get an usb-c to usb-a converter (they are pretty cheap)

you can use an old usb-a charger with an old usb-a to ligthning cable from a previous ios device or purchase both from new

or you can use a wireless charger
