Features: 1. DC to QC3.0/PD3.0/PPS cell phone smart fast charging module 2. Support protocol: QC2.0/0C3.0 (9V12V)/PPS/BC12//SCP// fast charging protocol VOOC/PD2.0/PD3.0 (5V 9V 12V 15V 20V) 3. Input voltage 8.2-32V DC; output voltage 3-20V (according to match to the fast charging protocol automatically adjusted) 4. Shell needs to be self-assembly 5. need to be installed by to avoid product damage Description: 1. Integrated dual-port USB-A and USB-C surge-type smart fast charging module 2. Input voltage: DC 8.2-32V 3. Output voltage: 3-20V (automatically adjusted according to the matched fast charging protocol) step-down type 4. Maximum output current of dual ports: 4.8A; maximum PD power is 27W (dual ports output simultaneously without fast charging); please strengthen ventilation and heat dissipation when using high current for a long time 5. Output voltage wired compensation function: 50mV/A 6. Switching frequency: 150KHz 7. No load: USB-A outputs 5V; USB-C has no output; dual ports with automatic plug and pull detection function 8. Conversion efficiency: typical value, 96% (measured when the input is 12V and the output is 5V) 9. Input reverse polarity protection: None (please confirm the positive and negative poles before powering on or add a series of 2-pole transistors by yourself) Note: Different Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Will Not Affect The Use Bare board size: about 51 x 30 x 15mm Material: PCB colour: As shown Package Contents: 1 x Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
