DROK DC Buck Converter Adjustable Voltage Regulator 12V 6V-32V to 1.5-32V 5A, LCD Screen Step Down Converter with USB Port and Protective Case

Received in brand new perfect condition. I’m really into electronics a lot. And being in ham radio you need devices like this. It was very easy to assemble and set up. Please watch the video and read the instruction sheet. Well made works fantastic! I just ordered two more. Highly recommended. 73

Works great super cool. So many possibilities.

The directions that come with it are virtually crap. Your best bet is to find a video like i did (unless you know and understand electrical operations, which i didn't).The wiring was very easy, but you need to build the housing, and hat ended up being the first nightmare as the directions were not helpful.The second, make sure you have a very, very, tiny flat head screw driver. As I even struggled with the YouTube video (a tiny bit), I decided to say "F" it and just start turning the screws. The left is the volts, and the right, as far I can tell is for... I dint remember. I just know I turned that one around 30 times before it did anything.That said, it works great. I'm running an old laptop power supply to my HO train set. As it is putting out 19 volts, I had to get it down between 12v and 14v continuous power. It works perfect for that. I'd buy it again.

I installed it in the same box as a low voltage motor controller for my DC ceiling fan. If the terminal connections were more substantial I would give it five stars. 16 gauge wire seems max, and that was tight. Easy to adjust and it's been working well. I like it.

Works perfectly for what i needed it for, which is to monitor voltage on my car audio system and also be able to power the little GPS tracker inside of it.. The USB is a great feature that can be turned on/off but i always have it set to 5.1v anyway and I think my current is limited to just under 3a so it doesn't try to start a fire too readily if there was ever an issue 😂You have to do a final assembly of it and the 2nd one I ordered was missing 2 screws but it's not a big deal with how I'm planning to mount it - but do better guys!Will continue to purchase and recommend: the voltage calibration is adjustable so you can fine tune to match any other meters you have. For less than $20 it'll fast charge your phone too?! No brainer 👌

The product looks OK, but the manual is confusing, which makes the product useless. In "Calibration Instructions" I followed it to set input voltage. Then I checked the USB output, which is 11.4, much higher than 5V I desire. In "Q&A" section, I found the answer: "output is set as around 20V before leaving factory. If your input is lower than that please turn voltage potentiometer ADJ-V anticlockwise for 10 laps or more until voltage changes." I guess the "input" could be a typo of output, so I start to turn the ADJ-V, no matter which way I turned, the number does not change. I have to return it.

I have only had this for a few hours, so I hope it lasts and I hope it’s reliable. But using it for just a few hours, it is simple and it works perfect! I want more! My application is very low current draw, just for low voltage solenoids but it definitely works. Thanks!

I like the display and the ability to tailor this device's output, and the usb connection is easy to set up. The problem is that it blows out very easily, and I've gone through 3!
