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!

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'm using this as a 13.8 volt power supply to run a 5 watt amateur radio using 4 18650 cells, so there's really no risk of over temp conditions. The voltage output is stable and accurate, measured with a Fluke 87 V. I initially considered assembling my own power supply, but the DROK is a better choice. Assembly and use are easy, and although the included instructions are a bit clunky (for lack of a better term) there are a handful of videos on Y-tube that help to clarify operation.

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.

It works great

USB puts out whatever you set the main output to. I was trying to run a 12V FM module and some USB powered LEDs. The LEDs were fried by the USB connection. Be aware of this! It is not a standard 5V USB! Just get a normal buck converter and a USB converter, as this doesn't do what it should :(

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.

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!

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.

Solide Verarbeitung., aber leichte Schwankungen in der Spannung und Strom. Beim Nachmessen mit dem Multimeter gibt es kleine Unterschiede in der Anzeige des Bausteins zur Messung, Ist für mich nicht so gravierend, da ich damit nur einfache Versuchsaufbauten mit entsprechender Spannung und Stom erstelle. Im Dauerbetrieb habe ich ihn noch nicht getestet.

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,
