I drive less than 15 miles on average per day. Would people advise against using a standard 110V outlet to charge a MS 60D overnight? I thought I read a 110V outlet charges 3 miles/hour - which would suffice for overnight charging. Any thoughts on this? Is it a bad idea? Obviously if I took a longer trip one day a night charge won't be enough but I am contemplating day-to-day commutes only right now.
