      Product corresponds to the description.
      Quality is very good.
      Construction is very small, as desired.
      Had some time ago, this product has ever bought.
      Am very satisfied today.
      Works reliably and without problems.
      Buy more of it.

        Q: if I set output to 5V, while input is 12V, what output will be, if I change input to for example 20V? Will it be still 5V? Thank you
        A:
        Yes. The input may change but the output stays constant. Remember to use a light load when adjusting the output.

        Q: Will the output voltage stay the same even if I change the load on the output?
        A:
        Most buck converters when used within limits keep the output voltage pretty well assuming the load increase slowly. A sudden increase in load will usually cause a drop in voltage. However the load vs no-load drop may be significant, so make sure to adjust with a light load. That's what the theory teach us anyways. In practice you will probably see a drop in voltage on the output if you increase the load. How much depends on the load.

        Q: no load
        A:
        This is part of the circuit and must be connected to be used.
