Thanks for the posting Brian but I can confirm all my power outlets and the cigarette lighter shut off 6 minutes after turning the car engine off even though I have plugged the ctek in immediately whilst they are all powered up stillBrianJ said:CTEK works perfectly with my 2013 981, using the footwell socket. Plug it in, turn it on, lock the car. A long time ago somebody said that yes, the sockets shut down after 6 mins, but if you plug the charger in and turn it on within 6 mins of turning off the ignition it keeps the socket live. I have never tested that, but I typically have just unlocked the car before I plug in the charger, which probably has the same effect. In this respect the footwell socket works just the same as my 987.2 Cayman S did. I have two CTEKs (MXS 5.0) of slightly different vintage (the newer one has an AGM setting and the other says use the winter setting for AGM) and they both behave just the same, working their way along the sequence of lights until they eventually get to the last green one. Hope that helps.
Oh, and by the way, as far as the driver's manual is concerned the footwell socket doesn't exist...
I have found the solution which is to buy a non Porsche Ctek which has the choice of various charging connection and with the comfort connector fitted to the battery terminal the ctek can then plug into this connection by passing all the computers that are switching the sockets off
