The output voltage adjustment potentiometer is next to the input voltage posts. When I powered on the supply the input voltage and output voltage were the same. Turning the potentiometer in either direction did not seem to have any effect but I eventually discovered that it needs many turns counter-clockwise before the output voltage started to lower (maybe 50 turns, I am not sure). Then I was able to set the output to the 5.1V that I need for the Raspberry Pi. And it is working great. The heat sinks are connected to the output voltage so be careful not to let anything conductive touch the heat sinks.

Bought one to retrofit a 6v electric trike to run on 12v lead-acid batteries instead of the original, proprietary 6v battery more than a year ago. It still works!

Solder joints, splatter and dirty board. Didn’t even try plugging it up. I’m glad I inspected it before use, putting out a fire was not on my todo list. Ordered a replacement, I’ll update

I see so many reviews of people reporting that this converter is broken. I have myself connected the input to the output and the output to the input and the variable resistor doesn't do anything. Note that the variable resister in on the input side and the power led is on the output side. Confusing I know, but the thing works well if you connect it right. I run some high amp astronomy stuff off these in some brutally cold weather. Works great.

Needed a buck converter for my robot projects, using a Dewalt battery pack. So far this is working great and I have no complaints except one. I had to rim the extra pieces of the PCB board (left over from the factory), in order for this board to match the others that I had purchased. Other than that, it was a great board and so far I am not having any issues.
