As part of our efforts to reach our environmental goals, iPhone 11 does not include a power adapter or EarPods. Included in the box is a USB‑C to Lightning cable that supports fast charging and is compatible with USB‑C power adapters and computer ports.
We encourage you to re‑use your current USB‑A to Lightning cables, power adapters, and headphones which are compatible with this iPhone. But if you need any new Apple power adapters or headphones, they are available for purchase.
The power adapter commonly used with the new USB-C to Lightning cable is https://www.apple.com/shop/product/MHJA3AM/A/20w-usb-c-power-adapter
The difference between it and the older power adapter is that it has a USB-C connection instead of the larger USB connection and it is 20 watts rather than the 5 watts of the older power adapter.
