Multi-Cell USB PD Power Bank with Quick Charge 2.0/3.0

Overview

With the growing use of smartphones, tablets, laptops, and other portable devices, consumers demand on-the-go charging solutions to keep their devices powered throughout the day. This high-performance portable charging design supports 60W+ with a full USB Power Delivery (PD) programmable power supply (PPS) and is suitable for multi-cell (2 to 4 cells) configurations. It integrates an advanced battery management system (BMS) and Bluetooth® Low Energy (LE) for real-time monitoring, ensuring efficient, fast charging with enhanced safety features.

System Benefits​:

  • Multi-cell configuration improves power delivery efficiency and capability, offering a flexible and scalable solution for various power levels.
  • Quick Charge (QC) 2.0 and 3.0 facilitate faster device charging and maintain backward compatibility with QC 2.0 speeds, providing flexibility for different devices.
  • Integrated BMS and Bluetooth LE monitor the power bank’s state of charge (SOC) and state of health (SOH), enhancing safety and contributing to longer battery life.
