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 Eddie Man
Suitable for small loads
Tiny power supply, I have the 12v version As noted by other reviews, the output pins are mislabeled, the middle pin is not connected to anything. the voltage drops to 11.5V and later to 11V and the current is only 0.33A. The smaller fan works fine, measurements show 12V 0.075A. Based on these limited tests I think the device is good will work as long as your load does not exceed 250mA (0.25A) and supplies 3W of power.
- Excellent design
