What portable iPhone battery / Charger do you like best?

For years I used this mophie Powerstation Plus With Lightning Connector

this has served me well for years and I love how thing it is with the built in cable that folds away. I love the form factor. I have a larger mophie battery that works for longer trips but looking for something small like I linked above.

I have a Apple MagSafe battery but I don’t love it.

I’d go for an Anker battery every time.
