This is a really powerful 12V power supply. I use it to power up the Car stereo together with an amp. It works with a full load and does not even get hot. 100% recommended product.

### ⭐ Way too noisy even on low power usage.
*by C***4 on 20 August 2024*

Cons: - Very noisy, the fan speed goes up and down continuously and it's very annoying and unbearable. - The output ripple is way too high because of very low quality capacitors. don't use this for any sensitive load. - Cannot handle even half of the claimed power output, fan goes to 100% burning smell all over the place and voltage goes down to 16v! Not recommended for anything important or high power. Pros: - Output voltage is adjustable to cover for wire loss. - Terminal has safety cover. - Ground is connected properly.
