I currently own a 2017 Audi A3 etron. We have been charging overnight on an extension cord, but the charger unit broke and I'm now looking at solutions. I'm thinking we will end up with another full electric in the next few years so I'm wondering about future proofing with a Level 2 charger. We don't have a garage so the unit would need to be rated to be outdoors in Toronto Canada. Any recommendations on specs and brand to be ready for the future without breaking the bank? Heather
