### ⭐⭐⭐⭐⭐ Review
*by S***S on 18 September 2018*

I use this to power a 200 Watt load from a 12 VDC supply and this converter doesn't heat up at all, meaning the conversion efficiency is high. This high conversion efficiency should also enable the converter to be mounted inside an enclosure, instead of putting it on the outside as shown in the pictures. The only negative I found it that the leads (wires) are about 4 inches shorter than I needed them to be in putting together my small project. Overall this product at $22 offers good value for your money.
