Hi gps-au, I have some of those in stoke and was going to put them up on my web site but the more I looked at them the less I liked them.
A good point is that they require a hole with only about half depth that a cig socket needs, but they require a square hole, not always the easiest thing for many people to cut and the PowerPoles that plug into them, stick out, so they are easily broken as one of the regulars on here has found out on a number of occasions.
To take full advantage of these you must use suitably sized cable or your just wasting your time.
If you can fit them somewhere where they won’t get knocked, they make great power supply sockets for bigger inverters and compressors.
