1. An external power bank apparatus with speaker, comprising:
- a microcontroller unit;
a power bank charging unit electrically connected to the microcontroller unit, adapted for receiving power from a power source;
a power bank battery unit electrically connected to the microcontroller unit and the power bank charging unit so that the power bank battery unit is charged by the power received from the power source;
a voltage boosting unit electrically connected to the power bank charging unit, the microcontroller unit and the power bank battery unit;
a discharging unit electrically connected to the power bank charging unit and the voltage boosting unit, adapted for connecting an individual portable electronic apparatus so that the power provided from the power source is directly applied to the portable electronic apparatus through the power bank charging unit and the discharging unit for charging a portable electronic apparatus battery unit of the portable electronic apparatus, or the power supplied by the power bank unit is boosted by the voltage boosting unit and sent to the discharging unit to supply for the portable electronic apparatus;
a speaker unit electrically connected to the power bank battery unit, so that the power is applied to the speaker by the power bank unit; and
an audio signal input unit electrically connected to the power bank battery unit and the speaker, adapted for connecting an audio signal output unit of the portable electronic apparatus so that music or audio signals are sent from the audio signal output unit to the audio signal input unit and voice or music is outputted from the speaker unit.
