My original wall charger recently died, at almost exactly the same time that I earned a referral credit, and therefore a new HPWC. It's supposed to arrive tomorrow. I have a dual charger in my Model S, and was previously getting 60mph at 80 amps on the old unit. I know the new model only charges at 72 amps, but I've also been told that that figure only applies to the newer cars, when the dual charger was discontinued, and that I can still get the full 80 amps. Who's correct on this? It seems logical that I could still get 80 amps since it's still below its overall rating.
