Thanks so much! I was kind of on that line after I read your earlier comment, but thought I would just ask. My jackery doesn’t have barrel plug outputs—just inputs. But it does have a 12V, 10A cigarette plug port. I’ll get an anker car charger like you suggested and use that.
I used DigiKam to face tag all my photos as I wanted a solution that wasn’t reliant on Google/Apple and kept the face data in the photo’s file. I thought it worked very well. I do wonder about whether I should just give up though and use a service.
