IP5389 fast charging power bank V1.2

Overview

Introduction

The IP5389 fast-charging power bank adopts a public mold casing on the market and integrates a 0.42-inch OLED display, which can display battery capacity, temperature, and charge and discharge voltage and current.

characteristic

Using Yingjixin IP5389_I2C_AACC fast charging chip, it can realize PD two-way 60W fast charging (without EMARK power)
Dual A port, 1 bidirectional TYPED C port
3 high-rate 21700 batteries, integrated battery protection and balancing chip, with NTC high temperature protection
Integrated STM8S103 microcontroller and 0.42-inch OLED display, which can display battery power and temperature, charge and discharge voltage and current
with lighting

Existing issues

Charging can reach 60W, but there is a problem with discharging. It will automatically cut off after exceeding 17W. We are still looking for the reason.
