DC Buck Converter

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.

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.

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 bought one of these to step down 24V to 12V for cooling fans on my 3D printer. So far, this little buck converter has been virtually flawless. It's easy to connect wiring, adjusting the voltage was a snap, and it looks pretty great, to boot!Pros:• Easy connections with screw-down clamp terminals• Easy to adjust outgoing voltage• Display can be adjusted to show incoming voltage, outgoing voltage, or both. And even amperage.• Looks fantastic. I love the clear, open "housing".• Includes small stick-on heatsink to keep things running coolly.• Everything fit together perfectly• Has a USB power output, in case you need to run USB devices from other power sources. (Likely need to reduce output to 5V.) This output can also be disabled.• Even has a spot to mount a small cooling fan to the clear acrylic over the heatsink.Cons:• No assembly instructions, though it's not overly complicated. (Hint: Look at the product photo for help.)• Voltage is off slightly, so I wouldn't call it overly-precise. Display says 12.0V out, and I measured 11.67V out. Good enough for my purposes.• Open housing can let in dust and debris, if that's a concern.• Included double-sided adhesive really doesn't stick all that well.Overall, the cons are pretty minimal for me. I'm really happy with this thing. We'll see how it does with longevity, but for right now it's been working great.

Trash trash trash , I am not bad with electrical and this thing won’t regulate. FILING A LAWSUIT ON THIS COMPANY

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

Great little buck converter, comes disassembled as acrylic is fragile but assembly is extremely simple and while a short guide would be nice it's not worth the waste of paper.

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!!!
