Ring Doorbell in Outdoor Socket

My problem simply The plug in adapter gen 2 is 7cm long and it bulges out of my outdoor double socket. I have tried to find a cable extension solution to no previle. I have tried to find other doorbell ac converters which will fit but they are all bigger than 5cm. Ideally I need a ring uk plug that connects to my 2nd gen adapter allowing it to be within the cable and not in the socket.
