I had that same DROK boost converter and it pooped out on me within like 3 hours, same with some other DROK one I had prior to that that also ended up shitting the can… dunno if mine were just duds or not… I’ll link what I’ve been using for almost two years, lots of that time mounted directly to my trucks under heavy vibration and it’s been bullet proof (at least having potted the larger components with E6000 to handle the vibrations), save for one mosfet I had to solder back on due to vibrating loose.
