    I have connected this up to DC motor being used as a generator for a low voltage wind turbine. This works very well.

    Solid PCB build around national semi buck converter. Max 8% loss - PCB heats up quite a bit when charging. Not tried yet with 3A of load but expect it to get hot.

    Not as high of an output as a higher quality converter but at a much lower cost. Useful for small solar panel power conversion. Better than the supplied converters on the panels.

    Works well to charge my phone from remaining RC flight batteries. The one I received was not very clean with residue of solder flux in places. Thanks to COV-19, I received almost 8 weeks after the order. Banggood is usually faster than that.

    Cool to have my own power converter for phone charging or for running 5v to electronic projects or other small appliances like a little fan
