12V aux power socket

How about a couple owf wraps of tinfoil
 
Yes, I resolved this issue in three ways on both the Rocket and the Tiger:
  1. Bend the center contacts in the socket inward, as they're too loose. They need to grip the center contact to help keep the adapter in the socket. WARNING: If the socket is live, such as the optional aux socket on the Rocket 3, don't use anything conductive to do this or, better yet, disconnect the battery first.
  2. Bend the radial contacts on the adapter itself outward a bit. I just use my fingernail.
  3. Use an adapter that's shorter and lighter. The Cllena and similar adapters are nice but they're long and heavy. On the other hand, the Optimate O-105 & O-114, and especially the "Kewig Aluminum DIN Hella Plug", are shorter and lighter.
The ISO4165:2001 plug is a really poor design, but passable if you do these things.
 
If you look inside at the middle of the 12v socket there’s 2 metal spring clips (for want of a better expression) which grab the central nipple on your usb hella connector. All you need to do is bend them in slightly with a screwdriver (ignition off) and you’ll get a tight fit, did this on mine works perfectly
 
Ditto - had the random disconnect issue very frequently till I did this and it has not happened since
