- 35W adapter USB-C port 1 → iPhone; port 2 → iPad. Published two-device category allocation: up to 17.5W each.
What the path requires
- Appropriate identified charging cables for each device.
- Read the occupied-port case instead of a single-port maximum.
- If one needs more power, remove the other device and its cable as Apple directs.
Different companions change the allocation
Apple gives a different category case for iPhone plus Apple Watch/AirPods: up to 27.5W and 7.5W. Do not apply that split to the iPhone-plus-iPad case.
