Type-C QC AFC DC Fast Charge Decoy Module Price in Bangladesh

The Type-C QC AFC DC Fast Charge Decoy Module is a compact USB fast-charging trigger board designed to obtain a supported higher-voltage DC output from compatible fast chargers.

A normal USB charger may provide only its standard output voltage until a compatible device communicates with the charger and requests a different voltage. A decoy, trigger, or protocol negotiation module is designed to perform this type of voltage-request function without requiring a complete smartphone or other USB-powered device.

This makes the module useful for electronics enthusiasts who want to repurpose a compatible fast charger as a convenient DC power source for DIY circuits, development projects, testing equipment, battery-related electronics, and other applications.

The module is designed around support for Quick Charge (QC) and Samsung Adaptive Fast Charging (AFC) protocols on compatible versions. When connected to a compatible charger, the board can request one of the voltage levels supported by both the charger and the module.

The exact selectable voltages depend on the particular board design. Common QC-compatible trigger modules may support voltage requests such as 5V, 9V, and 12V, while some versions provide additional voltage selections. AFC support likewise depends on the specific implementation and charger.

One important point is that this board does not create unlimited power by itself. The available voltage and current are determined by the connected charger, its supported protocol, cable, and the module’s design. If the charger does not support the requested protocol or voltage, the module cannot force it to provide that output.

The module can be especially useful when a project requires a higher DC voltage but the readily available power source is a USB fast charger. For example, a compatible charger capable of 9V or 12V output can potentially be used as the input source for a suitable DC electronics project.

The compact PCB design makes it easy to integrate into prototypes and DIY power systems. It can also be useful on an electronics workbench for testing circuits that require a regulated DC supply.

However, this module should not be confused with a USB Power Delivery (USB-PD) trigger module. QC and AFC are different charging protocols from USB-PD, and a charger supporting USB-C does not necessarily support every fast-charging protocol.

What is a Fast Charge Decoy Module?

A fast-charge decoy module is a small electronic board that communicates with a compatible charger and requests a particular supported output voltage.

The basic process is:

Fast Charger → Protocol Negotiation → Voltage Request → Selected DC Output

Without successful negotiation, many chargers remain at their default output voltage.

The decoy acts as the requesting device, allowing the charger to provide another supported voltage.

Working Principle

A compatible fast charger normally starts at its default USB output. The charger then checks whether the connected device supports an appropriate fast-charging protocol.

The decoy module performs the necessary protocol interaction.

For example:

5V Default Output → QC/AFC Negotiation → Request 9V → Charger Provides 9V

If 12V is requested and supported:

5V Default Output → QC/AFC Negotiation → Request 12V → Charger Provides 12V

The exact sequence depends on the protocol and charger implementation.

Once the charger accepts the requested voltage, the module provides that negotiated DC output to the connected circuit.

QC and AFC

Quick Charge (QC)

Qualcomm Quick Charge is a family of fast-charging technologies used by compatible chargers and devices. Different QC generations and implementations support different voltage and current capabilities.

A QC-compatible trigger board can request supported voltage levels from a compatible QC charger.

Samsung AFC

Adaptive Fast Charging (AFC) is a Samsung fast-charging protocol. AFC-compatible chargers can provide supported higher-voltage outputs after the appropriate negotiation.

A module advertising both QC and AFC can therefore work with a broader range of compatible chargers.

Voltage Selection

The exact voltage selection depends on the specific PCB.

Common trigger boards may provide options such as:

• 5V
• 9V
• 12V

Some boards may provide additional voltage options or use solder bridges, buttons, switches, or resistor configurations for selection.

Always check the actual board markings before connecting a load.

Selecting a higher voltage than the connected circuit can tolerate may damage the circuit.

• Exact output voltages depend on the module version and charger.
• Output current depends on the connected charger and module.
• It is not necessarily a USB-PD trigger.
• It is not a battery charger by itself.
• Higher voltage can damage circuits designed only for 5V.
• Proper cable and charger capability are required for reliable operation.

QC/AFC Decoy vs USB-PD Trigger

These modules are often confused with USB-PD trigger boards.

A USB-C connector alone does not determine which fast-charging protocol a module supports.

Installation and Usage Tips

• Check the output voltage before connecting your load.
• Confirm that the charger supports QC or AFC.
• Use a suitable USB Type-C cable.
• Start with the lowest available voltage when testing an unfamiliar circuit.
• Never connect a circuit rated only for 5V to a 9V or 12V output.
• Verify the polarity of the module’s output terminals.
• Ensure the connected load does not exceed the available current.
• Check the module markings before selecting a voltage.
• Do not assume every USB Type-C charger supports QC or AFC.
• Allow adequate ventilation when operating near the charger’s maximum power.
• Use an appropriate fuse or protection circuit for higher-power DIY projects.

Important Safety Note

The module can request a higher voltage from a compatible charger. Therefore, always verify the output voltage with a multimeter before connecting expensive or sensitive electronics.

For example, if a circuit is designed for 5V and the decoy requests 12V, connecting the circuit directly could cause damage.

The module should also not be treated as a replacement for a dedicated battery charging circuit. Lithium batteries require an appropriate charger and protection system designed for their particular chemistry and cell configuration.

Why Choose Type-C QC AFC DC Fast Charge Decoy Module?

This module is a practical solution for electronics enthusiasts who want to use a compatible USB fast charger as a convenient DC power source.

Instead of carrying separate adapters for every low-power project, a suitable fast charger can provide several supported voltage levels through protocol negotiation. This can be particularly useful on an electronics workbench or in compact DIY power systems.

Its Type-C interface, compact size, and QC/AFC compatibility make it a useful addition to an electronics prototyping toolkit.

Frequently Asked Questions (FAQ)

What is a QC AFC decoy module?

A QC AFC decoy module is a trigger board that communicates with compatible fast chargers and requests a supported DC output voltage such as 5V, 9V, or 12V.

Does this module work with every Type-C charger?

No. The charger must support the relevant QC or AFC protocol. A charger having a USB Type-C connector does not automatically support QC or AFC.

Can this module provide 12V?

Compatible versions can request 12V from a charger that supports the required QC/AFC voltage. The exact available voltage depends on the module and charger.

Does the module increase the charger’s power?

No. It only negotiates a supported voltage. The available output power remains limited by the connected charger, cable, and module.

Can I use it to charge a lithium battery?

Not directly. This is a voltage-trigger module, not a complete lithium-battery charging system. A suitable CC/CV battery charger and protection system should be used.

Is this the same as a USB-PD trigger module?

No. QC/AFC and USB Power Delivery are different protocols. A QC/AFC decoy should not be assumed to work with a USB-PD-only charger.

Can I use the output to power an Arduino?

Potentially, but the output voltage must match the Arduino board’s permitted input. For a 5V-only circuit, do not select 9V or 12V directly. Use an appropriate regulator when necessary.

How do I know what voltage the module is outputting?

Use a digital multimeter to measure the module’s output before connecting your project. This is especially important when changing the trigger voltage.
