Review on XINCOL DC 24V to DC 12V 50A 600W Buck Voltage Reducer Step-Down Regulator Transformer for Car/Truck Power Conversion with Dual Built-in Fans, Full Protections, Memory, and Inline Fuse by Edgar Gomez

Extremely fast delivery. I had a project I wanted to do in a month. That's why I ordered this part before the others as it comes straight from China. Two days later he showed up to me. Even Revain usually lasts 3 days. So I am very impressed with the delivery time. I have the 50A 600W version. I'm a bit skeptical about the wire gauge. For 50 amps I was expecting a few more sensors. Apart from opening the converter, it looks very good in terms of quality. The output was a constant 12-12.5V from the power supply, which fluctuates between 14V and 28V depending on the process. One thing that has me stumped is the yellow input wire labeled Key Ignition. As far as I can tell, it only turns on the fan. I have power whether I'm connected to it or not. I contacted the manufacturer for a manual and they sent me an updated one. (Very quick response and good English). The new management also gave no information about what it is doing. Now that my project is up and running and I've tested it, I specifically asked about it and will likely get an answer soon. Oh and one more thing, the input voltage range has been tagged with a lot of different things depending on what you read on this page or in different guides. I have yet to make it not work on the lower voltage end to make that end look solid. Although I'm a little scared going over 30 volts on the high end as I've seen 3 different numbers for the high voltage range. In general I am very happy with what I do.
