Nano Power Bank (5K, MagGo, Slim)

Wasn't sure about the slim design at first, but it's genuinely pocket-friendly and the 5K capacity gets my phone through a full day of heavy navigation. Charging speed is solid, way faster than my old brick.

This little thing slips right into my pocket and disappears, but it still managed to top up my phone twice on a long day out. The slim design is exactly why I grabbed it, and the charging speed has been solid so far. Just wish it came with a pouch for the cable, but that’s a tiny nitpick.
