Two I use a lot daily are KeePass 2 in various versions, computer as well as tablet. I used KeePass “original” 1 for years, but moved to 2/XC/DX. Occasionally also used for storing notes and not just passwords.
My notetaker, all hands down, though. Joplin, with encryption activated, the file stored for syncing on my privacy oriented community’s encrypted NextCloud. I am an avid notetaker, both digital and analogue, and Joplin really fits my needs.
OK, third, honourable mention: Veracrypt
As some others, I use Jerboa. Tried a few others, but happy with it.
I never charge my phone directly in public places. Instead I charge a simple powerbank I have, that then charges the phone. No idea how easy it is for that one to “be contaminated and carry something over”, but being simple, basically no features, just charging and a Led indicator, I suspect the chances are at least a lot less.
