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 electric energy is stored in advance in the form of chemical energy. When needed, the battery provides energy and generates electric energy to convert the voltage. The device (DC-DC converter) reaches the required voltage and is output from the output terminal (usually the USB interface) to supply the required equipment for power supply for charging or other purposes.
