Adjustable Voltage Regulator DC DC Buck Boost Power Converter 90W 6-36V to 0.5-36V 0-5A DC Regulated Power Supply with Cooling Fan, Constant Current Volt Step Up Down Module

This MakerHawk DC Buck Converter has been an invaluable addition to my electronics workbench. The wide input voltage range (6-75V) and adjustable output (0-65V and 0-22A) make it incredibly versatile for powering a wide range of projects.The included cooling fan effectively keeps the module from overheating, even under heavy loads, and the constant voltage and constant current functionality ensures stable and precise power delivery. Whether I'm powering motors, LED strips, or other demanding components, this buck converter delivers reliable and consistent performance.

Increments at 0.01 volts. I can find the difference but I can't verify calibration at that level. Mostly just bragging if you ask me. It is a nice little unit. I drove a 9W off road LED light down to 6.4 volts and found the current readout started having trouble around 12mA I think that's pretty good. Fun for my hobby lab and nice for camping. I wish the screen would dim and I want 7A at 14 volts. The support website comes up as not trustworthy and now it seems I cannot order another one. I may be pulling another star in the future.

I haven't tried all the controls through the display, which are numerous. But simply to get a flexible DC to DC converter at this price is pretty good. Look at those big capacitors. They go for maximum cooling by not even having a case.I wonder if a case with a case fan around it would run cooler or hotter. But it would have to cost more.
