Type-C PD/QC/AFC Fast Charge Decoy Trigger Module – 5V/9V/12V/15V/20V Fixed Output
[Step UP Buck Converter] Type-C PD/QC/AFC Fast Charge Decoy Trigger Module – 5V/9V/12V/15V/20V Fixed Output The Type-C PD/QC/AFC Fast Charge Decoy Trigger Module is a compact USB Type-C power negotiation module designed to request a selected voltage from compatible USB Type-C fast chargers and power banks. It supports QC 2.0/3.0, AFC, PD 2.0 and PD 3.0 protocols, allowing compatible USB-C power sources to provide higher voltage outputs such as 5V, 9V, 12V, 15V or 20V. This module is useful for DIY electronics projects where a USB Type-C PD/QC charger needs to be used as a DC power source for equipment that does not have native USB-C fast-charging support. ⭐ Key Features USB Type-C fast-charge decoy/trigger module Supports PD 2.0 / PD 3.0 Supports QC 2.0 / QC 3.0 Supports Samsung AFC Fixed selectable voltage output Supports 5V / 9V / 12V / 15V / 20V output options Negotiates the required voltage from a compatible charger Suitable for USB-C power banks and PD adapters LED indicators for operating/status indication Compact and lightweight PCB design Useful for DIY power supply and electronics projects Plug-and-play operation with compatible USB-C power sources 📋 Technical Specifications Product Type: USB Type-C Fast Charge Trigger / Decoy Module Input Connector: USB Type-C Input Source: USB-C PD/QC/AFC compatible charger or power bank Supported Protocols: PD2.0, PD3.0, QC2.0, QC3.0, AFC Output Voltage: 5V / 9V / 12V / 15V / 20V Output Type: DC Voltage Selection: Fixed/selectable depending on module version Indicator: LED status indicators Application: DC power conversion and fast-charge voltage triggering 🔧 Applications Converting USB-C PD chargers into DC power supplies Powering DIY electronics projects Arduino and microcontroller projects LED applications Portable electronic equipment DIY laboratory power supplies DC motors and other suitable loads Router/modem power applications where the required voltage matches Powering electronics from USB-C PD power banks Replacing conventional DC adapters with USB-C PD sources 🛠️ How It Works The module does not boost the USB voltage itself. Instead, it communicates with a compatible USB-C power source and sends the required PD/QC/AFC negotiation request. For example, when connected to a compatible PD charger, the module can request: 5V → 9V → 12V → 15V → 20V The charger then provides the negotiated voltage at the module's DC output. ⚠️ Important Notes The connected USB-C charger or power bank must support the required fast-charging protocol and voltage. A standard 5V-only USB charger cannot normally provide 9V/12V/15V/20V through this module. Always verify the selected output voltage with a multimeter before connecting your device. Do not connect a device that requires a lower voltage than the selected output. The module is a trigger/decoy board, not a standalone DC-DC boost converter. Maximum available output power/current depends on the connected USB-C charger/power bank and the module's specifications. Do not short the output terminals. 20V output can damage 5V/9V/12V-only electronics if the wrong voltage is selected. Exact selectable voltages and current capability can vary between board versions. 📦 Package Includes 1 × Type-C PD/QC/AFC Fast Charge Decoy Trigger Module
