Product Details

1. Principle

The principle of the mobile power supply is simple. When an external power supply can be found, the built-in battery is charged in advance, that is, input electric energy, and pre-stored in the form of chemical energy. When needed, the battery provides energy and generates electric energy, which is converted by voltage The DC- DC converter reaches the required voltage, and the output terminal (usually a USB interface) outputs and supplies the required equipment to provide power for charging or other purposes.


2. Basic component

Mobile power has three basic functions, including energy storage, charging and power supply. Other functions such as safety protection, battery status detection and display are added to meet the needs of different designs, uses and convenient operation.

It is a portable charger that can be carried with you, can store electrical energy by itself, and is mainly used to charge consumer electronic products (such as wireless phones, laptops) such as handheld mobile devices. It is especially used in the absence of external power supply occasion. Its main components include: a battery used for electrical energy storage, a circuit for stabilizing output

voltage (DC-DC converter ), and a charger circuit for charging the built- in battery. There are very few mobile power sources without a charging circuit, but they are almost extinct.
