Description
The USB Fast Charge Trigger Module is a compact and reliable board designed to simulate supported devices and request fixed output voltages from fast-charging adapters and power banks. It allows users to manually select and trigger specific fast-charge voltages without requiring a microcontroller.
This module does not include a voltage display, so a multimeter is required to confirm the output voltage after configuration. It is ideal for electronics testing, custom power projects, and fast-charge experimentation.
Key Features
- Supports major fast-charging protocols
- Fixed voltage output selection
- Simple dial switch / button-based voltage setting
- Stable and reliable performance
- Compact size and easy installation
- No firmware or programming required
Specification
- Input Connector: USB-A Male
- Supported Output Voltages: 5V, 9V, 12V, 15V, 20V (fixed levels)
-
Voltage Selection Method:
Adjust the dial switch according to the voltage table printed on the back of the board.
If set incorrectly, the module will output one of the available fixed voltages automatically. - Board Size: 30mm × 20mm
- Weight: 2.9g
Supported Fast-Charge Protocols
- PD 2.0 / PD 3.0
- QC 2.0 / QC 3.0
- AFC (Samsung Adaptive Fast Charge)
- DCP / Apple / Samsung charging modes
Application
- Triggering fast-charge power supplies
- Testing USB fast chargers and power banks
- Custom power delivery projects
- Electronics prototyping and lab testing
Important Notes
- ⚠ No onboard voltage indicator – a multimeter is required to verify output voltage
- ⚠ Output voltage depends on charger compatibility and selected protocol
- ⚠ Not a voltage regulator — it only requests voltage from supported fast chargers
