I have an electric Leaf and I've never, ever, used a "fast" charger. I've been plugging it in my 10A garden socket and it's perfect for overnight charging, it goes from 10% to 80% from dusk until dawn.

Annoyingly, I've already invested in a 11kW charger (with 22kW infrastructure) which I've never used!

You don't need "magical DC-charging" to go EV.
