Let's see:
3 times at Balboa Park, twice because I could, and once because I needed it.
Once at Torrey Pines, just to try it.
L1 at an appointment, because I really needed it.
During an overnight trip with the family to OC, once each at Laguna Beach, Fashion Island, and South Coast Plaza, plus overnight L1 at the hotel all needed to make the trip work.
I could really make use of charging at work and at the local shopping centers. There have been about three times where I've had to resort to our ICE because I didn't have enough juice to get through a busy day, plus a couple of times where an 80% charge didn't prove adequate because of unplanned trips.
