10 reviews for 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 : Electronics
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

Excellent Stepdown DC volt Unit
Excellent stepdown. I was looking for a unit to lower the voltage(speed) of a brushless 24 volt fan and this worked perfectly. I was able to slow the fan down to 12 volts and lower the noise from the fan. I looked for awhile and this unit is excellent for lowering the voltage (speed) of a 24 Volt DC fan. I highly recommend it.

Confusing at first
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.

Looks cool, and works well.
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.

Seems like a good product! Easy to use
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!

useless and returned
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.

Not only will it step down, but it will step UP as well.
I’ve bought multiple of these for various projects, but primarily for stepping the power output from my solar/battery powered security cameras from 24v to 5v. They’ve been working flawlessly for 2 years with zero maintenance or adjustment required.However while replacing my generic analog thermostat with a smart one recently, I found I didn’t have the 24v line required to power the new digital controller. What I had was a 5v wall charger and one of these adapters. I removed the circuit board from the wall adapter and mounted it inside the same box this converter comes in. It barely fit but it fit! I tapped power from the 120v line from the A/C unit into the 5v transformer, then patched the 5v output to the input on this converter, set the output to 24v and it’s also been working fine for over a year. While I realize that I could have just bought the 24v adapter, I wanted to finish the project before the weekend was over and this got me there. It’s still working so I see no need to swap it out.

not dual output
well, the output does adjust the shorted current is 2.5a. you cannot have 2 outputs, different, the usb reflects what it is set at, if you put it at 12v, the usb will not turn on until you make it 5 and also it will not power up a RPI. I was buying this thinking I could use 12v out AND 5v usb but I made an error. other than that its OK for the $$. it’ll charge a usb device with current limit so that’s OK too. just an FYI

Does not output 60W!!! Auto-shutdown at 43W with 20V and 24V!
This review is for:DROK Voltage Boost Converter, DC 6-30V 5V Step Up to DC 7-32V 12V 24V 5A Adjustable Volt RegulatorThe smaller ~$15 (at time of writing) boost converter. This thing advertised a maximum output wattage of 60W and recommended to stay within 50W, or at least that’s what the instructions say. It also has an advertised maximum of 5A and 30V, both of which were well above my needs. For my use case I have an 18V input, and I need 24V output that stays under 500mA for 90% of the time, so ~12W, but once every couple of weeks I will need it to pump out 2.4A for about 10 seconds, so that’s about 57W for 10 seconds on a very occasional basis. I figured with proper cooling, which it recommends, I’ll be fine. So while it was on its way to me, I went above and beyond and put several hours into designing a 3D printed case with a blower fan right on the power module’s heat sink, just to make sure I could keep it good and healthy.Imagine my disappointment when it arrived and I started testing it. When it is completely cool and hasn’t run at all, I turn it to 24V output and could not get it to go above 1.8A before completely shutting off. No “CC” light, no warning, no nothing just powers right off. So I turned the output voltage down to 20V, which is the lowest I can go according to the instructions when my input is 18V. With 20V, it made it to just above 2.1A before shutting down. None of the board’s components are hot or even warm. It didn’t even have time to get warm. This indicates to me that some internal control circuit is making the unit turn off when it gets to around 43W.Just to be clear, I did everything right according to the instructions. I went through the process of stepping up the load until the “CC”, or “Constant Current” LED lit up. Then I turned the potentiometer to the right to increase the current limit, and then increased the load until the LED lit up, and so on until I got to the values described above.This thing is obviously limited by a factory-set control mechanism that there is apparently no way to bypass. If they know they are limiting the device to 43W, then it’s incredibly dishonest and confusing to put in the instructions that it can reach 60W.I already have all of my own safety circuitry in place, so if I could bypass or disable this somehow then I would probably be OK with it. But since it appears to be built into the programming, this thing is just a disappointment. I love the size and the way it looks, so it’s quite the bummer.

on this purchase I bout 3 different versions, different vendors, of this type of power supply. The Drok version was by far the best for the cost. I will be buying more of these for sure.
