I'm trying to plan charging for a trip tomorrow and one of the locations we are stopping at has a Blink J1772 connector. It is not clear if I need to pay and/or if I need an account so I tried to reach the Blink web site only to find it down. Anyone know how the Blink network operates? Are some of the chargers pay and some not or are they all pay chargers? This one is at a Whole Foods store in Chatanooga, TN. All the similar stores I've been to didn't charge and didn't require an account with anyone to use the chargers.
