There was never a 12V supply! I received this power supply in a box and found that the voltage knob produced between 11V and 10V

3/5

With normal use, it is now stuck in the 9s after having driven LEDs for a couple of months. I can't increase or decrease the voltage with the knob of 8V. Since it does not supply a high enough voltage, my 12V LEDs are flickering now, so for me, it's basically trash. There are many other reviews that state that it does not get to 12V, so if that is important to you, do not get it.

This is not worth the effort

3/5

In response to your question, the product did not work out of the box. It would make approximately The potentiometer on the side won't enable it to go over 12 volts even with 5 volts and turned up. If it had to cope with a load of 20 amps, it would drop to 6 volts.

It works just fine after the fine tuning adjustment

5/5

With adjustment of the voltage I was able to use picky devices or LEDs, and it worked well for the price I paid. I can only hope that it will last in the long run, rather than complain.
