22.5W Bidirectional Fast Charging Power Bank Module – USB Type-C PD/QC

Product Description

The 22.5W Bidirectional Fast Charging Power Bank Module is a compact power management board designed to convert lithium battery power into regulated USB output for charging smartphones, tablets, and other compatible electronic devices. It also supports bidirectional power transfer through its USB Type-C interface, allowing the module to charge the connected battery as well as supply power to external devices.

Designed for DIY power bank projects and portable power solutions, this module integrates battery charging, voltage conversion, and fast-charging protocols into a single compact circuit board. It supports USB Type-C Power Delivery (PD) and Quick Charge (QC) fast-charging technologies, allowing compatible devices to negotiate suitable charging voltage and current according to the supported protocol and connected power source.

With a maximum advertised output power of 22.5W, the module is suitable for building custom power banks using compatible rechargeable lithium batteries. Its Type-C interface provides a convenient connection for both charging and power delivery, reducing the need for separate charging and output connectors.

The bidirectional design allows the USB Type-C port to operate in two modes: receiving power to charge the battery and delivering regulated power to an external device. This makes the board useful for portable battery packs, DIY charging stations, and custom electronics projects that require a rechargeable power source with fast-charging capability.

The module is intended for integration into a suitable enclosure with a compatible lithium battery configuration. Battery selection, wiring, thermal management, and enclosure design should follow the module's actual electrical specifications. The advertised 22.5W output is a maximum rating; actual charging performance depends on the battery voltage, battery condition, input supply, connected device, cable, and supported fast-charging protocol.

Before assembly, verify the module's supported battery chemistry, cell configuration, charging current, input voltage, output voltage profiles, and protection functions. These details can vary between visually similar power bank boards.
