Hi. Just bought a Delphi Granny charger from ebay for the zoe, i think Delphi is for the i3??. To my surprise its taking more longer than expected. What does the granny lead charge at KWH? From 30% it said 13 hours for full and in the morning when i woke up it was fully charged. A week ago from 10% it said 15 HOURS! Honestly thought the wire would charge at 3.7Kwh. More like 1.5-2kw an Hour. Thanks.
