Powerbank? Never bought one before

Wallet? I got this one off Amazonand really like it. Apple ones are kinda trash IMO

Charger? Anker is always a good bet. I have several of their chargers and never had an issue with them.

Little bit of both. I like having notifications sent to my watch now so I don’t have to whip out my phone to see if it’s an important one or not. Fitness also helps in that, at least, I can see if I’m being somewhat active throughout the day. Another portable MP3 player. And it’s a watch. Not much of a watch guy so it’s kinda nice having a “nice” watch to wear now,
