a standard wall outlet? my math is probably a bit off, but based on my electric bill stating that i pay $0.1037 per kilowatt, it would cost me $6.10 for a full charge. yes, no, maybe? i've seen it stated that it would take 30 hours for full charge using a 110 volt/15 amp wall outlet.

"Custom microprocessor-controlled lithium-ion battery with 6,831 individual cells. 3.5 hour charge time from empty to full using the Tesla High Power Wall Connector at 240 Volts and 70 Amps."

240v * 70a = 16800w / 1000 = 16.8kw * 3.5 hours * $0.1037 = $6.09756

110v * 15a = 1650w / 1000 = 1.65kw * 30hours * $0.1037 = $5.13315
