best circuit for DIY power bench supply i use a laptop charger(18.5v 3amps) as input little bit fluctuations in output but i think it's due to the input source.....highly recommend THANKS BANGGOOD

Got the item on time good built. Can start my project now.

Well, I made initial test (https://youtu.be/r63xqLkxc5Y ) and the module works fine. It is well assembled with good materials, has a good size and the module itself do what it has to do, adjusting output voltage of power supply with a very sensitive potentiometer. However, the onboard voltmeter connection is too weak and I broke it trying to figure out why it was not working (the voltmeter) . But how I am not pretending to use voltmeter as onboard feature, it does not matter. I can solder it with a pair of wires and everything is gonna be all right. Despite of incident, I'm very satisfied with product ! Thank you!

This psu module could not be simplier or smaller, but it does its job quite well. The voltage is stable enough, and I didnt feel more heat than I was expecting even when I used about 2 amps for a longer period. The whole stuff seemz like durable despite its tiny look. However, the built-in led display is generally useless in my case, since it stops working below 4,2V. I attached an external dual led display to monitor voltage output and current flow, this way it functions almost like an expensive tool-grade power supply.

Got this for a diy power supply project. Whole thing with heatsinks etc cost less than parts in local shops, Moved the display and potentiometer to top of casing due to size limitation - removing the pot was a bit tricky due to double sided soldering but doable. Very happy with my purchase.

Tested it and it remains very stable from no load to 90% of full rated load. The display is very accurate compared with a multi-meter. I recommend this small power supply to everyone building small 3V to 30V projects. My plan is to extend the display an insert in my breadboard experimenter case.

I used this in my DIY power supply and have been happy so far. Have not used this for very long periods at a time so don't know abut pot getting warm as others have mentioned. Useful never the less.

En general todo bien pero a tener en cuenta varios detalles. Aunque la salida es desde 1,25V el consumo del contador digital (3V) hace que no veas los dígitos hasta los 4,3V. Con el consumo del contador tienes q tener en cuenta que los V de salida serán los que metas menos 3V. Lo compre para regular una fuente de 12V por lo que no me servirá ya que solo veo desde 4.3v a 9V. Repito que fue error mio no leer bien el producto en ingles aunque no dan detalles tan concretos como los que he explicado.
