I have plugged in my Tesla to a regular 120v wall plug that charges "1kw" and requires overnight to fully charge.
We also have free chargers in my town that are faster. And of course the Superchargers which are the fastest.
Does it matter which type of charging I do (how fast it is) as far as the life and health of the batteries are concerned?
My garage charging is free (separate building from my apartment), and the town's chargers are free so I use these options most of the time. If I'm going on a 2-3 hour trip, I top off before or after at a Supercharger..
