Claim Text:
1. An electronic device having a fool-proof feature, comprising: a first magnet, generating a magnetic field; an output terminal, disposed in the range of the magnetic field and mated with an input terminal of a second electronic device, wherein the input terminal and the output terminal are detachable; a hall sensor, generating a hall voltage according to the magnetic field; and a power supply unit, coupled to the output terminal in order to provide power to the output terminal according to a control signal outputted from the hall sensor, wherein the hall sensor outputs the control signal when the output terminal is coupled to the input terminal and the hall voltage exceeds a specific voltage, such that the power supply unit provides power to the output terminal according to the control signal, and the second electronic device receives power from the output terminal, wherein the hall sensor stops outputting the control signal when the hall voltage does not exceed the specific voltage, such that the power supply unit is unable to provide power to the output terminal, wherein a second magnet of the second electronic device increases the hall voltage to the specific voltage when the output terminal is coupled to the input terminal correctly, such that the hall sensor outputs the control signal, and the power supply unit provides power to the output terminal according to the control signal.
