Does anyone know if there are any j1772 level 2 chargers on the market that plug into a 14-50 outlet? When I still dreamed of owning a Model S, I installed a 14-50 in my garage, and I would like to keep that available for the Gen III car I hope to own in 3 years, but since I will be driving a Volt for the next 36 months, I will need something that is j1772. Are there any level 2 chargers that I can plug directly into my current outlet without needing to re-wire anything?
