Review on π Efficient HiLetgo XL4015 Buck Converter: 3pcs Step-Down Modules 4~38V 1.25-36V 5A Adjustable DC-DC Step-Down Module - 96% Efficiency by Brad Davis
None of these worked at all
I tested them as soon as I got them and to my dismay they didn't work at all. I tried turning in all directions, measured with a multimeter (actually tried 2 different ones to be sure) both ways; I even tried another buck-boost converter I had laying around to confirm what the values should look like. However, the output values for all three did not change at all. It's a waste of money and time, don't buy it. I'll update my review to reflect an alternative converter if I find one that works.
- Input voltage: 4-38V
- Mostly ok but...
