คำอธิบาย
DC-DC USB step-down charging module (with working indicator light, standard gold-plated contact socket)
Compatible mobile phone models: Android series, iPhone series, Huawei, Xiaomi, Nokia. . .
Product size: 28*33*8mm
Product weight: 5.5g
Input voltage range: 6-26V
Output voltage: 5.2V (Considering the loss of the charging circuit, the output end is about 5.2V, and the load end is about 5V)
Output current: 3A (with no heat sink, the stable output current is 2A)
Note 1: The positive and negative poles cannot be reversed, and the input voltage cannot exceed 26V, otherwise the chip will be damaged!
Note 2: When the power is on, do not touch the sampling resistor and IC pin on the circuit board with your hands, otherwise it may cause a sudden change in the output voltage and damage the device!
Explain for some customers with poor electronic foundation: Don’t think that the nominal 3A current will burn the phone to burn the device! The charging current is determined by the phone or the device! The charging current of most mobile phones is 0.8-1.5A
