Using Steps:

Connect right input voltage at input terminal.

Connect USB device at USB terminal and use.


1>.Default output voltage is 5V.But its output voltage will change 3V-12V if connect a fast charging device.

2>.There is a LED load indicator.Weak flash when no load, the greater the load, the higher the brightness.

3>.Due to the large current, it is recommended to use a thicker wire.Wire cross-section greater than 1.5 square millimeters.

4>.Wire cannot be reversed.Otherwise the module will be damaged.

5>.It is a DC power module,So it can not connect to AC power.

6>.Please make sure input power is more than load power.

7>.Please step down output power if module is hot.

8>.Please read use manual and description before use.


1>.Solar panel to mobile phone charging

2>.Car charging retrofit

3>.Driving recorder power supply

4>.Household power supply transformation
