Review on π DAOKI 5 PCS AC DC Power Supply Buck Converter: Step Down Module 12v 5v 3.3v 9v - Efficient Voltage Conversion Solution by Justin Fletcher
A DOA and two others were tested under specification
Of the 5 3.3V buck converters, the first was DOA. The second one I installed could only source enough current for a 100mA device. The third block was tested in exactly the same way as the second, only being able to supply around 100 mA. I didn't bother with the other two devices. I only needed about 175mA to power my device and it couldn't deliver it. I do not recommend these.
