The 22.5W Ultra-Fast Charging Power Bank Module is a high-performance, industrial-grade solution for building premium portable chargers. At Electrapac, we recommend this board for advanced DIY projects where "standard" 10W charging isn't enough. This module supports nearly every modern fast-charging protocol, including Huawei SCP (22.5W) and PD 3.0 (Power Delivery).
Product Overview

This "5-Port" powerhouse is an all-in-one charging engine. It features a sophisticated bi-directional Type-C port that acts as both a high-speed input and output. Whether you are charging a MacBook, an iPhone, or a Huawei flagship, this board communicates with the device to deliver the maximum safe wattage (up to 22.5W).

Key Features for Electrapac Customers

• Five Integrated Ports: Supports every common cable type. No matter what cable you have (Micro, Type-C, or Lightning), you can charge your battery bank or your phone.

• Bi-Directional Type-C PD: The Type-C port supports "Power Delivery," allowing you to fast-charge the power bank itself and your devices using the same high-speed port.

• NTC Temperature Protection: This board includes a dedicated NTC Thermistor. Tape this sensor to your 18650 cells; if the batteries overheat during fast charging, the board will automatically cut power for safety.

• Digital Status Display Support: Compatible with small LED/LCD screens (usually included) to show exact battery percentage and the "Fast Charge" lightning bolt icon.

• Synchronous Rectification: Boost conversion efficiency reaches up to 95%, significantly reducing heat and ensuring your Electrapac battery cells last longer.

Wiring & Safety Guide

Building a 22.5W power bank requires careful assembly due to the high current flow:

1. Parallel Configuration: Connect all 18650 cells in Parallel (3.7V).

   Strict Warning: Do NOT connect batteries in series 7.4V or 11.1V). This will instantly destroy the main IC.

2. The NTC Sensor: Place the small black bulb (NTC) between your battery cells. This is your primary defense against thermal runaway.

3. Heavy Duty Wiring: Because this board draws up to 5A from the battery, use thick copper wires or pure nickel strips. Thin wires will cause "voltage sag" and prevent fast charging.

4. Activation: Once batteries are connected, plug a charger into any input port to activate the board.

Primary Applications

• Premium DIY Power Banks: Building a "SuperCharge" compatible bank with 20,000mAh+ capacity.

• Laptop Backup (PD): Providing a slow-trickle charge or emergency power to Type-C powered laptops and tablets.

• Custom Mobile Workstations: Integrating fast-charging ports into technician toolboxes or field kits.

• Solar Battery Storage: Converting stored solar energy into high-speed USB power for mobile devices.
