portable power bank

Overview

Design principle of portable power supply:
The portable power supply is a portable device that integrates power storage, voltage boosting and charging management. It consists of input charging control circuit, discharge control circuit, battery power detection and display circuit, charging indication circuit, battery protection circuit and main control MCU. The mobile power supply circuit uses Renesas R7F0C809 microcontroller as the main control chip.
