There has been a major controversy and mocking when Apple decided not to include their charge brick in its latest iPhones models.
Those chargers are NOT SMART enough. Usually charger brick checks the specification of the device when it’s plugged to deliver the proper amount of power
Even though you have an Apple Charger stated in Higher Wattage it will not charge some of your devices correctly.
If you have a 29W Power Brick it cannot take advantage of the MagSafe Duo instead of 29W it delivers only 15W of power. The 29W charger brick doesn’t support PD USB 2.0 or 3.0 even though it’s capable of delivering enough power.
