Abstract

A power bank apparatus with speaker combines the function of power bank and the function of speaker. The power bank apparatus not only charges the portable electronic apparatuses but also supplies power to the internal speaker. The voice or music of the portable electronic apparatus is amplified by the speaker of the power bank apparatus to improve the quality of the voice or music.
