The battery pack is used in portable charging cases. In today’s technology, charging is primarily carried out through these cases. One reason is that portable 3C (computer, communication, and consumer electronics) devices typically have smaller batteries due to their compact size, which limits space for larger cells. Additionally, integrating charging ports and other components would take up even more internal space. As a result, portable charging cases have become an essential and convenient accessory for on-the-go use.
