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

I had tried to design my own buck converter, taking the voltage from 14V to 5V and found that it was very difficult to do this reliably and with minimal noise on the output. I was looking to power an RF circuit. This Drok DC Buck Converter is amazing! It can handle the job with ease, and the output is very clean allowing my RF circuit to function properly. This converter has a place on the plastic housing for a fan, but so far heat has never been an issue while running at 1 amp or less. There are a few things to watch out for! First, make sure you have the converter set to the correct voltage before connecting power to your project. Secondly, the USB port can operate at voltage that are higher than normal USB spec. If you have the converter set to output 10V, the USB will also be 10V, instead of the normal 5V. This could damage equipment if you aren't aware. Next, the USB port does no remain enabled during a power off/on sequence. The converter WILL remember the voltage setting, but the port disables until you manually re-enable it. Idle current consumption is around 15-20ma at 14VDC, even with the display backlight turned off. Connections are all made using USB or screw terminals. Overall a top performer and good value for the price!

Overall a nice little converter. User beware: this thing arrives in pieces and you have to assemble it yourself. It's very easy to assemble though. You just need a Phillips head screwdriver to make it happen. Instructions aren't bad to interpret. I took pictures and posted them here for others to see prior to purchase if necessary. It doesn't come with any needs or anything like that so not a big deal but just be prepared to add your own. I like the acrylic cover. It makes the thing pretty. One last thing I wanted to throw in was that it is calibratable. You can ensure that whatever voltage you're putting in is actually that voltage by measuring with a multimeter and then telling the device exactly what that voltage is. Hopefully it will last me a good long time.

Bought a trail cam,built battery box for 12 volt dc jack,camera died in 2 days ordered different camera,this 1 turns out to be 6 volt,installed this guy which saved me from buying a 6 volt battery.Adjustable output voltage,usb port with adjustable out voltage,accuracy is great for my needs,draws almost no power,not much draw so heat is low and battery life has only dropped .02 volts in 2 weeks use.Lot cheaper than 8 AA alkaline s.

Works well and is easy to use. Love the features especially the display of volage and current. The 20 turn pots also make it easy to set the desired current limit, some products use a 270 degree pot to cover 0-10 amps that makes it near impossible to set an accurate limit. I didn't give it 5 stars because I wish it not only limited the current but turned the output off after the limit is reached.

The amps and voltage display is awesome! I have used the cheaper ones in the past but never realized how helpful and convenient it is to not have to probe the voltage and especially the amps. In addition, the 5 amp rating means everything is built stronger which is a plus. I highly recommend you spend the extra 5 bucks and get this well made converter. Just remember to turn the voltage pot counterclockwise about 10 turns until you get voltage regulation.

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 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!

Love this contraption, use them to make bubble boxes run extremely fast as it is a mini transformer!

Efficace et beau

Arrived on time and in good condition. Well wrapped/protected.

Es muy práctico, muy buena presentación, la carcaza protectora muy buena, regula muy bien. Muy recomendable para ser usado en proyectos.

Works with the Pi4 for me using the right 12v input, its just a shame the USB cant be automatily on after a power cycle,

Works Great!!!
