Product Information: DC-DC USB voltage reduction charging module Product size: about 33*33*8mm/1.30*1.30*0.31inch Input voltage range: 6-24V Output voltage: 5.2V (considering charging line loss, output end is 5.3-5.4V, 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 the chip will be damaged! 2. The input positive and negative poles cannot be reversed, otherwise the chip will be damaged! 3. When powering on, you can't touch the resistors, capacitors and IC pins on the circuit board by hand. Otherwise, The output voltage may be abrupt change to dam
