It wasn’t a problem for a couple of months, then started tripping out after charging. The last time we used it we plugged into a double kitchen socket via open window, not only didn’t it charge but the socket used doesn’t work either although now although the other one does. Has just been back to garage and they had same problem. They say it’s not a car problem or a problem with a lead, they are just sensitive and they found it happened to them if other electrical things were being used at same time. So we get car and cable back but it is as much use a a chocolate teapot. We can’t afford to keep getting electricians out to replace sockets, interestingly it didn’t trip the consumer unit. We have since installed a wall charger at a cost of £1500, with no problem so far and will have to use only this. Anyone else encountered this?
