Review on ⚡️ DROK 090187: Waterproof DC-DC Volt Buck Converter Step-Down Regulator 8-50V to 5V 3A Power Supply Module with Micro USB Adapter Connector by Don Acevedo

This item worked, I bought two and use them to power a pair of Raspberry Pis. from a self-sufficient 12-volt power supply system. They run cool and the micro USB connector is fine for my application. The packaging is clean, no open components. Although I haven't used them, the small mounting tabs can be very helpful for a clean install. I noticed that one of the micro USB connectors needs to be inserted gently and fully to make good contact. It was a great solution to power my Pi directly with 12V DC. I haven't done any load testing but for now they only support the Pi and the input voltage has dropped to 11.4VDC on a low sun day and 15VDC on a sunny day. They serve my purpose well.
