Yes, It won't latch on. i.e it won't 'Click'. I took my ProAC charging set to AutoZone's 'Test me' adapter and it 'clicks' and fits in perfectly.
I even took AutoZone charging set and tested as well. even their's don't 'Click' on my adapter. Attached few pics. Or may be the adator on my boxster is wornout? or a wrong adapter?
