I'm looking at purchasing a 2012 or 2013 Leaf....I would strongly consider a 2012 if I could increase the full charge rate from approx 8-4 hours. My question is, I have a 240 outlet in my garage for power tools, it is either a 25 or 30 amp breaker, can I use this outlet with one of the under $300.00 converted plugs I've seen advertised on this site or is it impossible to increase charge time until the 6.6 charger is available.?
