Extension cord
I am thinking about getting an extension cord for charging my Tesla. It will have to go about 30 feet. I am planning to use it to charge overnight from what I believe to be a standard household outlet on my deck. Since I live in Chicago and the cord will traverse the yard on the ground, I anticipate that it will often be covered by snow for weeks at a time in the winter.
I will consult an electrician before doing any of this, but it would be useful if anyone could comment from personal experience about this scheme & what kind of cord to get?
(My objective here is not so much to charge the car, but to keep the battery in decent shape, particularly in the winter.)
