I've used these a few times, most recently to power a wifi security system in my camper. I was able to put the system completely behind a wall so that it's inaccessible to any would be intruders...

This adapter was exactly what I needed to hardwire my Rexing V1P Plus dashcam to my 2011 Mazda3 fuse box. The wires are a light gauge so be careful stripping for assembly. It's small and fits easily in the fusebox space.
