I had trouble using my J1772 adapter at a Chargepoint station over the weekend .The adapter would not click into the J1772 plug and so charging would not start. There were 4 different stations at this one garage and I tried 2 of them. I have previously had a problem with an EATON charger in Baltimore, MD but using what I consider to be excessive force I was able to get the adapter to click into the J1772 plug and charging proceeded normally. The worst part about this whole thing was that b/c i was not able to charge (and I was only 10-15 miles short of the range I needed) it added over an hr to my trip time b/c I had to drive from Salem to Dedham (in traffic) and then back to Auburn, MA. (the deviation alone was 10 miles in each direction. The thing is I have a clipper creek CT 100 at my summer home that I use the adapter with a few times a month without incident. it works flawlessly. has anyone else had trouble using the J1772 adapter with ChargePoint or EATON chargers?
