CH224K Fast Charge Decoy Trigger Module: Get Fixed Voltage from PD/QC Chargers! DIP Switch Selectable 5V/9V/12V/15V/20V, Supports PD2.0/3.0, QC2.0/3.0, AFC – Power Your DIY Projects, Laptops, and Development Boards.

Key Features & Benefits:

🔌 Multi-Protocol Compatible: Supports PD2.0/PD3.0, QC2.0/QC3.0, AFC fast charging protocols, compatible with most fast chargers on the market.

⚡ Fixed Voltage Output: DIP switch selects 5V, 9V, 12V, 15V, or 20V – five common voltages to meet various device power requirements.

🎯 High-Precision Trigger Chip: Uses dedicated CH224K trigger chip for stable protocol negotiation and accurate output voltage.

🛠️ Easy to Use: Clear voltage table printed on the back – simply set the DIP switch according to the table, no programming required, plug and play.

📏 Compact Size: Only 31×20mm, 2.9g, easy to integrate into any project.

💻 Wide Applications: Power laptops, drive development boards, create adjustable power supplies, retrofit old devices, and more.

Product Description:

Have a spare PD fast charger but can't directly power your 9V/12V/15V/20V devices? The CH224K decoy trigger module is your ideal solution. It emulates a sink device to negotiate with the charger, extracting the desired voltage, which you can easily select via DIP switches. Whether powering a Raspberry Pi, a router, LED strips, or building a DIY adjustable power supply, this module makes it effortless.

🚨 Critical Notes Before Use!

❌ 【No Voltage Indicator】：The module does NOT have an output voltage indicator. ALWAYS use a multimeter to measure the output voltage before connecting your load to ensure it matches your setting and avoid damaging your device.

⚠️ 【DIP Switch Must Be Set Correctly】：Strictly follow the voltage table on the back of the module. Incorrect settings may cause the module to output any of the voltages (5V-20V), potentially overvolting and destroying your load. Measure after each switch change.

⚠️ 【No Stepped Voltage】：The module outputs only fixed voltages (5V/9V/12V/15V/20V), not continuously adjustable. If you need an intermediate value (e.g., 8V), consider other solutions.

⚠️ 【Input Source Requirements】：A charger that supports the corresponding fast charging protocol (e.g., PD charger, QC charger) is required. Regular 5V chargers will not trigger fast charging; the module may have no output or default to 5V (depending on the charger).

✅ 【Correct Usage Steps】

Connect the Type-C input to a fast charger (e.g., PD charger).
Set the DIP switch according to the desired voltage using the backside table.
Measure the output voltage (on pads or header pins) with a multimeter to confirm.
Disconnect power, connect your load, then reapply power.
🔧 【Wiring Instructions】

The module typically has pads or header pins labeled VOUT (+) and GND (-). Observe correct polarity.

If you purchased the kit, use the included USB-C female breakout board for easy wiring.
