DROK Buck Boost Voltage Regulator, DROK DC 6-30V to DC 0.5-30V 5V 12V 24V Adjustable Voltage Converter, 4A 60W Power Supply Step Up Down Transformer Board Module with USB Port Case LCD Display Volt Am

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!

The unit has a nice display and a well-designed industrial layout, with easy-to-access buttons for setting the parameters. Depending on your application, you may need to install your own heat sink. We purchased several of these. One of them didn’t work out of the box, but the seller promptly replaced it. Great customer service! Very pleased with the purchase. Thank you!

Ordered one, voltage adjust worked fine, but current adjust didnt work straight from the "box". Ordered another one, and neither voltage nor the current adjust works again straight out of the "box". I'd imagine if i ordered 2-3 more one of them would be ok but then its for how long, dont and wont know

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.

Works great to adjust voltages from various sources to specific voltages.

I built a barn door style equatorial mount to photograph the 2024 eclipse. I used this to regulate the voltage from an 8 AA battery pack to a 12VDC 3RPM motor. I used a 20T pinion gear on the motor drive and a 54T drive gear to move the mount. By dropping the voltage down from 12v to 10.7v, I achieved 1RPM on my drive gear which was spot on. As the batteries depleted, this little guy kept my output quite steady. As a precaution, I mounted a 40mm fan on the back. I just spliced it in to the input side. As a suggestion for DROK, a header to plug a fan in on the PCB would have been a nice extra. I am very pleased with the way this product works.

Before install I connected to a 12-volt power source and it blew a trace pulling 800mA after less then 1hr...Drok in my opinion is quality gear but im dissatisfied at the moment with my purchase. If Drok customer service makes this right I'll update my review...thanks for reading

Very nice The only problem with USB: Sometimes it randomly disconnects when charging , idk why

Functions as advertised. The pots to adjust the voltage and current are a little inconsistent but still functionable. Nice display size.
