Recommended single cell 18650 compact power bank for the pocket?

[chbla]

Hi there,

Can anyone recommend a single cell, replaceable 18650 or even 21700 power bank/charger with either
USB or USB-C that is compact to use in the pocket?

The Thrunite C2 would be nice but the reviews are not so good... I've got a Folomov magnetic charger
but they disconnect too easily to carry them anywhere.

Thank you!

Hey there,
I like and use a Nitecore F1. It's very small and has a nice feature set
