Comment Level 1 charging disadvantages and danger (Score 1) 196
Level 1 charging is more like 1.44kw/h not 1.9kw/h because you should not exceed 80% of the capacity of a 15A circuit so 12A * 120V and at that rate charging an empty EV battery is around 2 days so not very practical. While this situation is not typical it can happen , that's why I have level 2 charging at home and a full recharge is around 8 hours. Also charging at level 1 is not very safe in the long run due to the premature deterioration of the 120V outlet due to constant heating, many cases of burned plugs with level 1 charging have occured , it's a lot safer to use a more robust charging system.
