I spent the first month and a half on a level 1 set up, basically an extension cord in my driveway and I was surprised that I only had to go to a faster charging station twice. One of these two times was just because I was curious to try it. You could argue the second time was just anxiety because my remaining charge never went lower than 20%.

The only reason I still got a level 2 chargers at home was because I have doubts a level 1 will be enough to charge in the colder months of winter.
