I completely disagree that the solution in the central garage is Level 1 chargers so they could install more of them. Sorry, but the problem with Logan is all the spots are usually occupied by cars like @EdA who are no longer charging. No offense, I think you had good intent, but did you think about those who came after you who might have really needed a charge but couldn't because your car was sitting there for days without charging? I was there Dec 17 and again on the 21st and both times every spot was taken by a car that was plugged in but not charging. On the 17th I was picking up a passenger and 120v would have been utterly useless for the short time that I was there. As it is the 30A Chargepoints are almost useless.
Level 1 (120v) might be a good solution for the economy (long-term) lots. The solution for the Central garage is more powerful chargers, not less, and they should charge a fee to use them. With a fee you would only need half as many chargers because only those who need it would plug in. It would also provide funds to install more of them instead of meeting the budget by cheaping out with only 120v. If they were charging a fee I bet it would have eliminated the problem I had of driving 2.5 hrs and then nowhere to plug in because a lot of "local" cars were almost full by the time their planes took off.
