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 Hesham Peltier

I used these as part of a project involving powering multiple Raspberry Pi 3 B+s mounted on a DIN rail. of them and installed them on the back of the DINrPlate s, and bam I had a USB power supply for each of my Raspberry Pi boards. It's almost impossible to find USB power adapters that deliver more than 2.5A, so this setup made it easy. I haven't done any extensive testing related to voltage or current, but I can say that all my Raspberry Pi boards have been working great for the past few weeks. Good product, good price. As I expand my Raspberry Pi cluster I will definitely buy more of these.
