I bought two generic, 300W 20A buck regulators for my kids power wheels. As soon as I hooked them up, they burnt up!!
Polarity was correct, voltage was only 17V, almost no load, just some LEDs.
Turns out the screws holding the heatsink were cranked on so tight, they ripped through the solder mask and shorted out to the output + terminal... terrible design, and totally not my fault!
