The IP5328P Dual USB Fast Charging Module is the ultimate "all-in-one" solution for building a high-end, professional-grade power bank. At Electrapac, we recommend this board for advanced makers who want to move beyond simple 5V charging and embrace Quick Charge (QC 3.0) and Power Delivery (PD) standards.

Product Overview

The IP5328P is a highly integrated multi-protocol power management IC. It manages the entire process: charging your lithium batteries from a USB source and boosting that voltage to 5V, 9V, or 12V to fast-charge your devices. It supports almost all modern fast-charging protocols, making it compatible with the latest smartphones from Apple, Samsung, Huawei, and Xiaomi.

Key Features for Electrapac Customers

• Multi-Protocol Support: Automatically detects the connected device and selects the fastest possible charging speed (up to 12V).

• Two-Way Type-C PD: The Type-C port works as both an input (to charge the power bank) and an output (to charge your phone), supporting the Power Delivery standard.

• Synchronous Switching: The high-efficiency boost converter minimizes heat, ensuring your Electrapac power bank doesn't throttle during high-power 18W sessions.

• Smart Power Indicator: Features 4 onboard LEDs to show battery level (25%, 50%, 75%, 100%) and a dedicated "Fast Charge" indicator light.

• Full Safety Suite: Includes protection against over-voltage, under-voltage, short-circuit, and high temperatures, keeping your lithium cells safe.

Wiring & Assembly Guide

To ensure your high-speed power bank performs reliably, follow these assembly rules:

1. Parallel Battery Setup: You can use multiple 18650 cells to reach high capacities (20,000mAh), but they must be wired in parallel (3.7V). Connecting them in series will destroy the module.

2. Wire Thickness: Because this module pulls and pushes high current for 18W charging, use thick copper wires between the battery and the B+/B- pads. Thin wires will cause "voltage drop" and prevent fast charging.

3. Initial Activation: After soldering the battery, you must plug a charger into the input port to "activate" the board and start the output.

4. The Button: A single press checks the battery level; a double press turns off the output; a long press can toggle a small LED torch if equipped.

Primary Applications

• High-End DIY Power Banks: Creating a custom charger that matches the performance of retail "Fast Charge" brands.

• Portable Field Power: Powering 9V or 12V electronics (like wireless routers or monitors) directly from a USB power bank board.

• Project Enclosures: Integrating a professional charging interface into 3D-printed handheld devices.

• Outdoor Gear: Building rugged, high-capacity portable power for long-distance hiking or camping.

• Device Repair: Upgrading older power banks with modern QC 3.0 and Type-C PD capabilities.
