I can turn the adjusting pot 360° and get the same 4.04 volts, this is just with my multimeter possible with a load I might be able to adjust the output, so far very disappointed.

Very good down converter
I needed a 5 volt source to drive USB type drone battery chargers. I used this converter to build a 12 volt driven field charger that has four 5 volt channels allowing me to charge 5 drone batteries at once.
These micro converters work well. The only caveat is that you must turn the adjustment pot to max and back to min a few times and then set it to full clockwise. Connect your source and then adjust the pot slowly until you get the desired output voltage.
So far no problems with these units and they work great.

Not able to adjust voltage
I ordered 4 of these, it must take a special tool to move the adjustment so I am unable to adjust the voltage making them so much junk to me. This is the first thing from MPJA that I have had trouble with.
