it would be nice if the level 1 supplied charger could somehow be locked to the charge port on the leaf. right now, I use the charger in a public parking garage that has a standard 120V 12 amp outlet. I am always worried that someone will realize these charging cables are worth $400 and steal them. I am thinking about running a 300V 12X3 awg extension cord through a partially open window and keeping the transformer inside the car while it charges. It would definitely work even though the owner's manual clearly states that extension cords should not be used with the chargers. What do you guys think?
