I have a Volt and ELR. Max-charging is 15A / 240V, so I'm stuck with the Level-2 J1772 chargers through PlugShare, etc. Here in Colorado Springs, there's some Superchargers by Tesla installed (finally!) I know that Level-3 chargers are primarily for the Model S, but I was wondering that since the adapters by Tesla are likely to be the Tesla-standard (not the J1772), what would happen if I plugged a Roadster into it? Would it work? Also, aside from the 3.0 upgrade, can a Tesla Roadster handle a ChadeMo or Direct-Current charger with an adapter? Don't own one yet.. looking at options. Trying to decide if the 2.0/2.5 is worth it.
