Where to get one of these?
Discussion
AlexT you haven’t mentioned the price point or which eBay seller(s) you have looked at. Clive at https://www.cccharger.co.uk/ sells the adaptors. Not sure if that’s any help to you but many on this forum have bought exhaust valve switches and battery conditioners from him, so he comes well recommended. HTH a bit. BRM.
I made one: just buy a MagCode connector and use a spare ctek cable for the other end. I think I cut the crocodile clips off a set and used that.

I do not use one of these as they can be problematic. The connection can dislodge or not align well causing a high resistance. These were used on Bentley as well, some had dead batteries when they assumed the car was on a maintainer.
On my DB11, I've hardwired the terminal accessory to a main feed circuit. Easy connect and I can close the bonnet after connection. I feel better with this option.
