...if you have the dual car charger option. There is a thread over the Tesla Motors forum where we have found a Canadian user who happens to have dual chargers who has been able to charge at 24A from a TT-30 adapter. I have a single car charger in my car, and I can only charge at 20A with 120V. The few people that have tried charging with TT-30s must also have had single chargers because this is the first time I've heard of anyone charging at 24A from a TT-30. If anyone here has a dual charger car and access to a 30A 120V source and has the appropriate home made adapters, it would be great if we could confirm this finding, but at this point, I don't have any reason to doubt it. I still believe that the single charger 20A limit at 120V is a software limitation put in by an over zealous programmer who didn't realize that things like 30A TT-30 outlets existed. ---------------------------- Update 4/17/2013: At this point, the evidence is pointing to higher VIN cars being able to charge at 120V, greater than 20A, rather than dual versus single chargers.
