Internal parts of the MacBook power adapter

For professionals, every component of Apple is worthy of careful study. Ken Sheriff, who has recently disassembled and compared the genuine and high copy iPad power adapter, gave us a disassembly diagram of the MacBook power adapter. Let us see It is a very complicated structure inside. As can be seen from the disassembled picture, this adapter contains a large number of circuits and also contains a microprocessor.

The MacBook adapter that was disassembled this time is 85W and the model number is A1172, so it can be guessed that it is the MacBook Pro power adapter. These pictures can help you distinguish between genuine and high copy chargers: Apple logo On the case, the metal (not plastic) grounding plug is on the right and the serial number is next to the grounding plug.

This looks strange, I found that the best way to open a charger is to tap the gap around it. As the case opens, you can see the metal heat sink of the adapter, which helps to cool the high-power semiconductor inside the adapter. The other side of the adapter shows the board, the bottom is the power output, and some tiny components can be seen, but most of the circuit is covered by a metal heat sink and fixed by yellow insulating tape.
