Yes, but not so simple lately. The Kearny Supercharger has grown in popularity with the ever growing Tesla fleet in this area, so it is often really backed up. On Monday, in the middle of the day, I was planning to head there as part of a larger trip to run several errands, but instead opted for Newport because Kearny was showing a long wait. And, that has become a very common occurrence for that location. Overall, the best availability is always at the mall. Yeah, it sucks that you have to pay to access the chargers (the fee is now $4, minus the JC resident discount, if you bother getting your ticket validated) but there are always multiple stalls open for use.
