Review on [2 Pack] High-Power DC-DC Buck Converter with LED Display - Step-Down Voltage Regulator 4-38V to 1.25-36V - 5A Module by Cre Soto

I bought these to use in a project to step down the voltage of a 20v power tool battery to 13.5v to use as a portable power source to use. I found the onboard display very helpful in setting up my project. Eliminates the need for an external counter for tuning. I used the Fluke DVM to test for accuracy and it turned out to be accurate. I also loaded the device with 5 amps and it worked as advertised. Just remember to attach the included heatsink when using it at current limits. I have used similar devices in projects for several years and it is difficult to find decent quality high current devices. These devices fill the bill. Highly recommended.
