Review: Works right out of the box. - Really useful item when you need it. No complaints. It takes a few minutes to understand the controls, but that's really all. It might have helped if I looked at the instructions. If you're looking at this converter, you already know what it does. Updated Review a year later: Buy it. I needed to know the kick-on voltage for a board/display and this proved more valuable than my desktop adjustable power supply. This has more fine-tooth control that's responsive, and doesn't necessarily have to kick in until you press the button. It's jumped 12v to 23-24 and dropped 12v to 3.3 (and lower) without issue. Easily a worthwhile purchase.
Review: Functions well, but no cover for back - Does the job, but overly complex user interface for my application. Also, it really does not come with a case. The photos show components protruding out the back but still I was surprised there was no cover.

### ⭐⭐⭐⭐⭐ KISS -- Keep It Simple Stupid
*by E***I on May 7, 2025*

It works, and can be set up for basic operation easily. It comes with a full-color instruction sheet. That said, the instructions are not easy to understand and the number of functions is mind-boggling. Just understanding what those functions are is challenging. But DROK did have the decency to set the startup defaults for the most likely use -- providing adjustable voltage at unrestricted amps. Keep the instruction sheet. Maybe even give it a once-over. But hope you never have to use it. I predict frustration.
