Description;
DC-DC USB buck charging module (with work indicator, standard contact gold-plated socket)
Compatible phone models: Andrews series, iPhone series, Huawei, millet, .
Product Size: 28 * 32 * 8mm
Product weight: 5.5g
Input voltage range: 6-26V
Output voltage: 5.2V (consider the charge line loss, the output is 5.2V or so, the load side is about 5V)
Output current: 3A (in the absence of heat sink device, the stable output current is 2A)
Note 1: positive and negative can not be reversed, and the input voltage can not exceed 26V, otherwise it will lead to chip damage!
Note 2: When working in power, you can not touch the circuit board on the sampling resistor, IC pin, otherwise it may lead to damage to the output voltage of the device!
For some of the poor electronic base customers say: Do not think the nominal 3A current will burn the phone burn equipment! Charging current is determined by the phone or equipment! Most mobile phone charging current is 0.8-1.5A.
