Step-down DC-DC USB charging module (with working lights, standard gold plated contacts socket)
Compatible Phone Model: Andrews series, iPhone series, Huawei, millet, Nokia. . .
Product size: 28 * 32 * 8mm
Product weight: 5.5g
Input voltage range: 7-26V
Output voltage: 5.2V (loss considering charging circuit, the output terminal is about 5.2V, the load side is about 5V)
Output Current: 3A (without a heat sink, the stability of the output current is 2A)
positive and negative can not be reversed, and the input voltage can not exceed 26V, otherwise, it will cause damage to the device!
When the power of work, can not touch the hand sampling resistor circuit board, IC foot, may cause damage to the device output voltage mutations!
