    For those wanting to dabble with a Apple MagSafe PowerSupply (common with the newer Apple laptops), here the pinout.

    I was exploring the option to use it as a 5V power supply, but unfortunately it’s giving us 16.5 V (when load is applied).
    Without any load on it only 6.8 V is supplied. The connector is magnetic and can be flipped.

    pin 1 : Ground (GND)
    pin 2 : 16.5V DC
    pin 3 : Charge control LED and adapter ON/OFF (when battery is charged)
    pin 4 : 16.5V DC (= pin 2)
    pin 5: Ground (GND = pin 1)

    See also attached image.
