I've been starting to read up on the various charging options - is there a good FAQ somewhere? I want to take the 85 kWh Model S on a 470km trip which means I'll need to stop somewhere for a charge. Because it will have twin chargers I'm hoping I can get that top up a little quicker. What I'm not clear on is the impact of the different plug options on the rate of charge. At this point my understanding is that I should look for the highest amperage outlet possible, but with standards at play I'm not sure if that changes between the 14-50, J1772, etc...
