Sự miêu tả
Tổng quan
QC2.0 / QC3.0 decoy trigger board with USB 2.0 male plug and an enclosed housing. It requests a specific voltage — 5V, 9V, 12V, 15V or 20V — from a Quick Charge capable charger or power bank, so a fixed-voltage device can be powered from it.
Thông số kỹ thuật
- Trigger output: 5V / 9V / 12V / 15V / 20V (one fixed voltage per board)
- Protocol: QC2.0 / QC3.0
- Interface: USB 2.0 male plug
- Housing: enclosed casing
- Function: replaces a boost converter for fixed-voltage loads
Mục đích
Many QC chargers can output 9V, 12V or 20V but only do so when a device asks. This board does the asking, turning a phone charger into a fixed 12V or 20V supply. For devices that draw under about 2A, it is a cheaper and smaller alternative to a boost converter.
Ứng dụng
- Powering 9V / 12V / 20V devices from QC chargers
- Portable router, radio and access-point power
- Bench testing fixed-voltage equipment
- DIY projects replacing a boost module
Cách sử dụng
- Choose the board with the voltage your device requires — the output is fixed, not adjustable.
- Plug the board into a charger or power bank that genuinely supports Quick Charge. A plain 5V source cannot be triggered and will only supply 5V.
- Connect your device to the output, observing polarity.
- Keep the load within what the charger can deliver at that voltage (typically 2A).
- Check the output with a meter before connecting an expensive device.
