Rene you could be right the majority of the time I charge up using my dedicated Podpoint overnight, to date I have never taken a full charge of a commercial charger, I have taken an 80% charge of a fast charger. I have plugged the granny charger into the external 13-amp socket on the caravan whilst on site which take about 5 hours, the last hour seems to take forever.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
