No, because a family isn't generally seen as slow; whereas the sub section in society it IS directed at, unfortunately is. Maybe too (yet another) another sterptype exits that 'Gran' is not likely to have a dedicated EV wall charger too? It gets worse.Would calling it a ‘family charger’ taking your argument infer that the family is ‘slow’
Note that link I posted also refers to the slow/gran aspect of the nomenclature.
If I were Gran i would be offended at the common language used to describe it, just as i would be if I were a member of a minority group and a particular type of cable was used in a way to mock my situation/status.
