18.5v power adapter 85w charger for apple macbook

18.5v power adapter 85w charger for apple macbook

Each time the MagSafe power supply is plugged into the connector on the side of the Apple computer, the following steps will be taken:

Before plugging into the computer, MagSafe only maintains a very weak current of about 100 µA
The moment the plug was sucked into the Apple computer, the MagSafe power supply detected that the very weak current mentioned above encountered a resistive load, and the resistance value also matched, so it began to supply power at full power. After the Apple computer detects that there is power supply at the power port, it reads the identity information stored in the MagSafe chip through the contact in the middle of the interface, and then accepts the power supply after confirmation.
