I didn't want the hassle of going into my fuse box, and this paired nicely with my Thinkware FA200 with the rear cam.
Installation was a breeze. For reference, I drive a 2016 GTI, but the cord provided more than enough length for pretty much any make and model. It allowed me to place my dash cam where I wanted it to, and was able to hide the cable easily enough.
I'm still able to change voltage settings in the Thinkware app, so I'm not worried about this cable draining my battery when it's parked for extended amounts of time outside.
This is a great option for those that don't want to mess around with a fuse box, but want to have their cables hidden, keep their car charger port free, and want to use additional features like parking mode. High recommend!
