The fast-charging trigger module (PD Decoy) is a modern solution that provides a stable supply voltage from chargers that support the Power Delivery (PD) protocol. The module decodes the 12 V voltage at the hardware level, ensuring a stable and safe power supply for electronic projects. This product is ideal as a power supply for the ESP8266, ESP32, Arduino, and Raspberry Pi (when used with appropriate step-down converters).

Key Technical Features

• Output voltage: 12 V DC
• Maximum output current: 5 A (requires appropriate wiring)
• Supported protocol: Power Delivery (PD) with constant voltage only
• No support for: QC2.0, QC3.0, QC4.0, or PPS
• Dimensions: 19.4 x 10.5 mm
• Weight: 1 g
• Control circuit: hardware identification chip

Example applications

• Powering DIY projects and embedded systems (for Arduino, ESP32, ESP8266, and Raspberry Pi)
• Powering 12 V LED strips from power banks or USB-C chargers
• Portable power systems for 12 V routers and network devices
• Creating power adapters for audio and video equipment
• Powering DC motors in robotics projects
• Integration with IoT systems requiring a stable 12 V power supply

Benefits

• Power versatility—allows the use of standard USB-C PD chargers to power devices requiring 12 V.
• High efficiency—support for currents up to 5 A enables powering devices with higher power consumption (a CC cable with an E-marker chip is recommended).
• Stability and safety—the module limits voltage fluctuations within the PD range, minimizing the risk of overheating.
• Compact dimensions—the miniature size facilitates integration into small enclosures and projects with limited space.
• Ease of use—this hardware solution ensures a constant voltage output without the need for additional configuration.

Additional Installation Information

The module requires precise installation. Carefully check the insulation of the positive and negative terminals to prevent short circuits and potential damage to connected equipment. The module does not support voltage levels other than the specified 12 V and is not designed for voltage regulation.

ℹ Note

• The specified parameters represent the module’s maximum capabilities—the actual voltage, current, and power depend on the profiles actually provided by the connected charger or power bank.
• Before connecting, check the available voltages on your power supply in the “Output” section on the housing.
• The device is not a voltage converter, but a trigger (emulator) that forces the power supply to output a specific voltage.
