The demand for power consumption is also increasing day by day. However, the market requires these products to be lighter, thinner, and smaller, which leads to the smaller and lighter volume and weight of the built-in battery, and the capacity of the battery is also reduced; thus, the market has a backup power supply ( The power supply itself can be charged and discharged many times), as a backup power supply, when the battery power of the mobile phone or other electronic products is insufficient and the user is inconvenient to charge with the charger, connect the backup power supply, and the mobile phone and other electronic products can be charged. The product's internal battery charges and provides power for its use.

However, the output interface of many backup power supplies used in the market is separated from the backup power supply itself, and the user often loses the output interface; However, due to the hard connection between the output interface and the backup power supply, when the backup power supply is plugged into the mobile phone and other electronic products through the output interface for charging, due to the principle of leverage, it is easy to damage the mobile phone interface, and the protective cover of the output interface on the backup power supply is also easy to lose. ; In addition, because the backup power is also rechargeable, it also needs to be equipped with a charger, but the interface and electrical parameters of the charger of the backup power and the original charger of the mobile phone are different, and each backup power needs to be equipped with a charger. Bring inconvenience, but also increased cost.
