DROK Buck converter did the job! My Radio Control Transmitter was eating through AA batteries. I switched to a Lipo battery pack but needed to regulate the output voltage. Using this DROK Buck converter and Lipo battery - I can fly with confidence that I have long lasting consistent power for my Drone.

I ordered it with the case and it arrived with two baggies.. One had the board and the other the case as flat pieces of plastic, screws, standoffs and heatsink. There were no instructions of any kind. It didn't take long (and only second attempt) to assemble. It's still not entirely clear what the buttons do or how to properly adjust the pots. There are also nice cool blue and green flickering lights that have an unknown function. I do have it running and it appears to work well so it's a bargain at the price.

Working fine, need an in line filter since equipment is sensitive to noise. (Which we should have known) not product fault. Has only been running for a short time, can't comment on product longevity.

besides the annoying assembly of the acrylic case, the product works wonders and makes testing projects so easy. Even in permanent solutions, its great!

Item came on time and in good condition, it was well packaged not overboard to where it would be irritating\annoying. Some assembly was required, and there were no instructions on how to do so. It is pretty straight forward it only goes together one way and the board layout matches up perfectly with the openings and screw holes in the acrylic case (if you have to force it in any way you're probably doing it wrong). Operation is just as simple, connections are well labeled on the circuit board and there are only two adjustment points one for desired voltage output and the other for the maximum amount of current desired. After using it in a few different setups to test functionality I am very pleased with its consistency and ease of operation. Will definitely be making future purchases from Drok. Thank You.
