I just got a new iPhone 11; it arrived with a charging cable, but not with a wall adapter. I have plenty of old adapters, but the power cable is too small and doesn't fit into them. Do I have to buy another adapter?
If you have the cable for the old power adapter you can use that with the new phone.
If you need to or want to buy a new adapter to go with the new cable, see: Buy 20W USB-C Power Adapter - Apple
