What Wigwam says is correct.
Wall chargers make most sense if you intend to A: “smart charge” (off-peak, agile tariffs etc), and B: intend to use the “auxiliary” heating/preconditioning. Some cars (i’m not sure about the Tucson, but factually for the GTE) don’t precondition fully through a granny charger. My wife needs the car proper warm before entering due to one of her conditions, a granny charger doesn’t do it for us.
