I can't get myself to do the battery-built-in-to-charger thing. I've always treated portable power banks as semi-disposable since they do eventually get worse and fail, and it feels icky to me to tie ~immortal charging gear to something that will die.

I did have the same feeling about flashlights for camping/hiking with lithium batteries, though, until someone walked me through just how much better they are than lugging around AAs.
