18 w。
In terms of charging, Apple has provided the iPhone with a 5W charger for 12 years as standard,
Until the 2019 iPhone 11 Pro changed the 5W charger to 18W PD fast charge,
When iPhone users finally enjoy the fast charge, the 2020 iPhone 12 not only does not come with the 18W PD fast charge head,
Even the 5W charger is no longer included. The same goes for this year's iPhone 13.
