IP5328P Power Bank Bidirectional Fast Charging Module Product Overview

The IP5328P power bank bidirectional fast charging module is a highly integrated fast-charging solution based on the INJOINIC IP5328P power bank SoC, designed for single-cell lithium battery power banks and portable energy storage devices. It integrates a synchronous boost converter, lithium battery charging management, battery level indication, and multiple fast charging protocols, enabling a complete power bank function with minimal external components.

The module supports 2×USB-A output ports, 1×Micro USB input port, and 1×Type-C bidirectional input/output port. Each port supports fast charging when used individually. The Type-C port supports USB PD bidirectional fast charging. Housed in a QFN40 (6×6mm) package, it uses a single inductor for both buck and boost conversion, significantly reducing BOM cost and board space.

FAQ:

1. What is the IP5328P power bank module and what are its core strengths?
   The IP5328P is a highly integrated bidirectional fast‑charging SoC for DIY power banks. It combines a 5A synchronous boost converter, a 3A linear charger, USB‑C PD3.0 negotiation, and multi‑protocol fast‑charge support (QC, FCP, SCP, AFC) in a single chip. Its key strengths are an 18W PD output, up to 5A charging current, and the ability to boost a single 3.7V Li‑ion cell to 5V, 9V, or 12V, making it a complete solution for compact high‑power portable chargers.

2. What is the maximum charging current and output power of the IP5328P module?
   The module supports up to 5A input charging current via the Type‑C port, enabling extremely fast battery top‑ups. On the output side, the USB‑C port delivers up to 18W with PD 3.0 (5V/3A, 9V/2A, 12V/1.5A). The USB‑A port also supports up to 18W (12V/1.5A) with QC2.0/3.0. The actual combined output is typically around 18–20W, depending on the battery and thermal conditions.

3. Which fast‑charge protocols does the IP5328P support? Can it charge both iPhone and Android devices quickly?
   It natively supports USB PD 3.0 (18W), Qualcomm QC2.0/3.0, Huawei FCP and SCP, and Samsung AFC. The chip automatically detects the connected device and selects the optimal protocol, so it can fast‑charge both modern iPhones (via PD) and a wide range of Android phones without any extra adapters or firmware changes.

4. What battery configuration does the IP5328P support? Can I use multiple cells in series?
   The chip is designed exclusively for a single 3.7V Li‑ion or Li‑Po cell (1S configuration). It does not support multi‑cell series packs. For larger capacity, you can parallel multiple identical cells while keeping the same voltage. The module includes over‑charge, over‑discharge, and short‑circuit protection for the battery.

5. How does the battery level display work on the IP5328P?
   The module can drive up to 4 LEDs to indicate remaining capacity in 25% steps. Most ready‑made boards include an onboard LED bar and a push button to wake up the gauge. Some versions also offer an I2C interface for connecting a small digital display module, allowing a more precise battery readout.

6. How efficient is the IP5328P boost converter, and does it need active cooling?
   The synchronous boost converter achieves over 92% efficiency at 5V output and around 88–90% at 12V. At the full 18W output, the chip and inductor become warm but normally stay below 60°C with basic airflow. For sustained heavy loads, placing the board in a ventilated enclosure or adding a small heatsink to the inductor is recommended.

7. Is the IP5328P module difficult to solder for a DIY project? What are the critical connections?
   Most modules come pre‑assembled; you only need to solder the battery wires, the USB‑C/USB‑A connectors (if not already fitted), and an optional power switch. The main IC is already soldered. The critical connection is the battery: use short, thick wires and ensure solid solder joints to minimise voltage drop. Double‑check the polarity, as reversing it will destroy the chip.

8. Does the IP5328P support pass‑through charging (use while charging)?
   Yes, the module can charge the battery and power a device simultaneously, though the output power may be limited when an input is present. Some boards disable the USB‑A port while charging; check your specific board’s behaviour. In general, the USB‑A port can often be used while the Type‑C port is receiving power, but the total output may be reduced.

9. What are the maximum input and output voltages of the IP5328P?
   The input accepts 5V on the Type‑C port, but the internal charger can draw up to 5A. The USB‑C output delivers 5V/3A, 9V/2A, or 12V/1.5A (PD 18W). The USB‑A port outputs up to 12V/1.5A with QC. The chip automatically manages the boost and charge functions, so no manual switching is needed.

10. What are the most common applications and the main limitations of the IP5328P?
    It is used to build DIY 18W power banks, portable USB‑C chargers, upgrade old battery packs with PD, and serve as small backup power supplies. Its main limitations are: single‑cell operation only, no 20V PD profile, and noticeable PCB heating during 5A charging, which requires good battery welding and thick copper traces for reliable performance.
