Dual USB output 9V/12V/24V to 5V 3A DC-DC car charging buck regulator charging module Product size: 33*33*8mm Product weight: 6.2g Input voltage range: 6-24V Output voltage: 5.2V (considering charging line loss, the output is 5.3-5.4V, the load end is 5.1-5.2V) Output current: 3A (the stable output current is 2A without heat sink) Note 1: The input voltage should not exceed 24V, otherwise it will cause chip damage! Note 2: The input positive and negative poles cannot be reversed, otherwise the chip will be damaged! Note 3: When powering on, you can not touch the resistors, capacitors and IC pins on the circuit board by hand. Otherwise, the output voltage may be suddenly damaged and damage the device!
