USB-C
What is a USB-C and how is it different that the USB from my iPhone 6? I just purchased a new iPhone 11.
iPhone 6, iOS 12
USB-C is a newer smaller connector that is reversible.
You can use the new USB-C cable that came with your iPhone 11 with Buy 20W USB-C Power Adapter - Apple or other USB-C power adapters.
Or if you have both the cable and USB power adapter from an older phone, you can use them.
