HW-398 Fast Charge Trigger and Booster Module

The HW-398 / CTP9 module is a DC-to-DC boost converter (9–20V) that allows you to extract higher voltages from fast chargers and power banks. With this board, you can turn a USB Type-C fast charger or power bank into a stable DC power source, enabling devices like routers, fiber modems, and other DC-powered equipment to remain powered continuously. This ensures internet and network access remain uninterrupted during power outages, making it an essential tool for homes, dormitories, and remote setups.

In addition, the module acts as a fast charging protocol tester (PD/QC/AFC) and can convert certain older DC devices into a USB-C powered system, making it perfect for electronics projects, lab experiments, and DIY applications. The board includes four fixed voltage outputs: 9V, 12V, 15V, and 20V, selectable simply by shorting the corresponding pad on the board. The module intelligently synchronizes with the charger, and if the selected voltage is not supported, it automatically drops to the highest available safe voltage, ensuring device protection.

This module provides a small, cost-effective, and practical solution for powering critical equipment and DIY projects, delivering a reliable and professional experience.

Important usage notes for HW-398 / CTP9:

• Avoid using low-quality or fake USB-C cables, as the module will output only 5V in all cases with such cables.
• If a higher voltage (e.g., 15V or 20V) is selected but the charger or power bank cannot support it, the module will automatically lock to the highest voltage the charger can provide. For example, if the charger maxes at 9V, the output will be 9V.
• The maximum current supported is 5A, but the actual output depends entirely on the charger capacity and the load connected.
• The power source must support PD or QC standards; standard 5V chargers cannot supply higher voltages.
• Some high-power chargers with proprietary or non-standard fast charge protocols may not be fully compatible (e.g., Xiaomi fast charge might not be recognized).
• When soldering the voltage selection pads, use minimal heat—just enough to melt the solder. Excessive heat may damage the board, lift pads, or make the shorting difficult.
