I own a model S and charge it with a NEMA 14-50 (50A) outlet in my garage. We're considering getting a Volt as a second car. Chevrolet tells us the only way to charge the volt @240v, requires installing a $2,300 charger in our garage. Two questions if anyone has knowledge in this area: 1) Would the tesla charge cable + the J1772 adapter work on a Volt? Has anyone tried it? 2) Is there an alternative option to charging the volt via my NEMA 14-50 outlet (50A) without buying an expensive charger? Thanks!
