I am traveling to the Block Island Ferry in New London CT for the 4th of July weekend. I will be parking in the municipal garage for the long weekend. There is a J1772 charging station in the garage which i plan to take advantage of. I will need to charge for about 10 hours to have enough charge to get home on Monday. My concern is that I feel like i will be blocking the station for 3 days when I will only need it for 10 hours. Should i feel guilty?
