65W Type-C PD Fast Charger Module 5V-20V Multi Protocol

65W PD3.1 USB Type-C DC-DC Fast Charging Power Delivery Module 8-32V Input

The PD65W USB Type-C fast charging module is a compact high-efficiency DC-DC power delivery board engineered for modern USB-C powered electronics. The module converts a wide DC input voltage into a negotiated USB Type-C output using intelligent communication protocols. It automatically detects the connected device and delivers the correct charging voltage, ensuring safe and optimized charging performance.

This module is particularly suitable for DIY electronics builders, robotics developers, portable power designers, solar battery users, and embedded system engineers. With support for PD3.1 (PPS), QC3.0, SCP, AFC and other fast charging standards, the board allows a standard DC source such as lithium battery packs, 12V car systems, or 24V industrial power to operate modern smartphones, tablets, and USB-C laptops.

Due to its high conversion efficiency and protection circuits, the module provides stable output with minimal heat generation. Bigyan Project users commonly integrate this module into portable lab power supplies, custom power banks, and field electronics where reliable USB-C power delivery is required.
