1. This PD/QC/AFC Type-C USB fast charging trigger board can be used as a DC power supply, supporting 9V/12V/15V/20V USB boost line Type-C charger, aging dormitory power outage router modem adapter. 2. The board allows users to trick the voltage of fast charging chargers/power banks and use them as a direct current power supply source. 3. With this board, users can easily convert some traditional DC-powered devices to ones that use a TYPE-C interface. This feature allows users to power older devices with modern and more efficient charging methods. 4. Multiple Protocol Support: The board supports various fast-charging protocols, such as PD3.0/2.0, PPS/QC4+, QC3.0/2.0, FCP, and AFC. These protocols enable faster charging times and more efficient power delivery to compatible devices. 5. The board is an essential accessory for homes and offices, especially in areas prone to power outages. It guarantees uninterrupted power supply to critical devices like routers and modems, ensuring seamless internet connections even during blackouts. Power supply method:Use a charger with a fast charging protocol or a power bank TYPE-C interface for power supply Output mode:fixed 9/12/15/20V four gears Output current:Maximum support of 5A, actual output current/power determined by charger and load Precautions: 1. Fixed 9/12/15/20V four gears, what voltage is needed, just short circuit the corresponding solder pads. 2. For example, if you set a trap of 20 volts, but your charger only has a maximum of 9 volts, it will automatically downshift to trap the output of 9 volts. 3. Mobile phone chargers must first support fast charging such as PD/QC in order to trick out voltage.
