Tips
Each double-layer USB shares a 5v3A chip, dual insurance solution, two double-layer USB independent power supply, each 3A, the total current is 6A.
The output voltage is between 5.08~5.18v
Wiring method:connect the positive voltage of the voltage of 7 to 38v to the input positive, the negative voltage to the negative of the lower icon, the four USB will have a stable 5v voltage, plug your mobile phone data cable into the USB. used. The output is convenient for those devices that do not have a USB cable. It is for professional use only. If you don’t understand it, you don’t need to worry about this interface.
Built-in Apple identification resistor, 47k+56k, 2.7v. Apple’s charging current is about 2.4A; Android phone is about 1A. Please use a good quality data cable.
Near the terminal block, there is a diode ss54, which is an anti-reverse diode. Professionals can short-circuit it, and can change it to a fuse and toss it by itself.
Q:My mobile phone current is only 1A. Will your 3A converter burn my phone
A:No; 3A means that the high current that this converter can withstand is 3A. As long as your device can be used below 3A current, the voltage is the same. The current is adaptive and built by the mobile phone. Chip controlled, this power supply is only available in standard 5v. As long as the working voltage is 5v, it can be used.
