Support QC4+/PD3.0/ and other fast charging protocols, suitable for mainstream devices. Up to 140W, meet the fast charging needs of high-power devices such as laptops/mobile phones DC6-30V input, suitable for various power supply scenarios such as car/power supply Integrated thermistor temperature protection, and equipped with an extra-large heat sink, safe and does not damage the machine Multiple protection mechanisms input overvoltage, undervoltage protection, output overcurrent, short circuit protection, etc. Module input method problem: This module can be understood as a charger that integrates multiple protocols, but it cannot be connected to AC power. It needs to be used with a DC power supply (power adapter). It is recommended to use a 24V DC power supply. If you need a 100W output, consider the power life at *20%, so choose a 24V5A power supply; 200W output requires a 24V10A power supply. Input voltage:DC6-30V Recommended input parameters: DC24V 7A Boost and buck type: buck (input must be output 1.2V) Input and output type: only supports output (battery power supply is not recommended) Output interface:USB-A and USB-C Input socket size:5.5x2.1MM (DC5521) Size: 68*18.2*32mm Color:As Shown Material:PCB Package Contents: 1 * Smart fast charging module 1*PD3.1 Charger 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.
