Information

The principle of the mobile power supply is simple. When the external power supply can be found, the built-in battery is pre-charged, that is, the input power is stored in advance, and when needed, the battery provides energy and generates electric energy to the voltage converter ( The DC-DC converter is used to reach the required voltage, and the output terminal (usually the USB interface) outputs the power supply to the required equipment for charging or other purposes.

basic component

The mobile power supply has three basic functions, including energy storage, charging and power supply. Other functions, such as security protection, battery status detection and display, etc., are added depending on the design, usage and convenience of operation.

Energy storage (battery)

In order to supply power to other devices without an external power supply, the mobile power supply needs to have a battery for energy storage. Most of the mobile power batteries use lithium-ion batteries or lithium batteries, and a small number of mobile power supplies use nickel-metal hydride batteries. There are also some mobile power supplies that use a battery.
