According to apple, it's for the sake of environmental protection to let the iPhone cancel the attached headphones and chargers. At the same time, there are too many similar devices in our home, so we don't know whether we will pay for it.
For those who buy iPhone 12,Apple's official documents show that if you want to really feel the fast charging power of the new machine, you still need to equip them with their 20W fast charging head (with c-to-l line attached), but your existing 18W is not very good.
In other words, those who buy the iPhone 12 series still have to pay 149 yuan to buy Apple's new 20W quick charger.
As can be seen from the document, iPhone 11 is equipped with 18W power usb-c power adapter, however, users need at least 20W power to give full play to the fast charging power of iPhone 12.
What happens when the iPhone 12 is plugged into the iPhone 11's 18W charger is unknown.
PS: if Apple forced this matching charging power back to 5W, would you really ignore the iPhone?
