Review on ⚡️ Adjustable Voltage Regulator 0.5-30V 4A 5V 6V 12V 24V Power Module - DC DC Buck Boost Converter for CC CV, Ideal for Laboratory Power Supply by Vinny Howard

The module is rich in functionality and the manual is surprisingly well written for this class of product. But with multiple buttons to set or view them, it can be a bit tricky to set up and control. Intuitive. No, that is not so. Don't lose your guide! The display is easy to read in the dark or in bright sunlight (in transflective mode). Good calibration function. Using as a battery maintenance tool for a car parked outside, using the voltage, current limit and undervoltage functions and the corresponding module protection settings. So far, so good. Section 1.4 "Considerations for children” states that the product prevents water flow back. An interesting feature that I haven't figured out how to test. Since I couldn't find a manual online, I've posted a scanned manual that came with the product to share with others.
