I have the public charging cable, at first I thought it was just like an extension cable with the same type of connector, male at one end and a female at the other. I now see from your photo Paul that it is the same as that so it must be a Type 2 to Type 1 cable. Is it a case that if the Type 2 plug fits into the charging socket then it will be safe to use? This is what I tried today and failed at, more due to the instructions supplied by Chargemaster which only covers the 13 amp connection and not knowing to leave it for a short time to communicate.
