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) Support full-speed PPS3.3-21V 6.3A 133W Support PD140W 20V7A@140W Support QC5/QC4+/QC3+/QC2.0 Support AFC/FCP/high voltage SCP/SFCP Output power problem: Since the module is a step-down module, the output must be the input 1.2V. Since 140W is 20V7A of the PD protocol, it can only be fully output if it is 21.2V. Battery power supply problem: The module can only output and cannot charge the battery. If it is only powered by a battery, it can be used with a 24V battery pack. If it is a car 12V, 12V cannot be full power, the PD protocol is up to 36W, and it is no problem to only charge the mobile phone. A port and C port output at the same time: Single-channel A port and C port can output at the same ti
