Anker MagGo Power Bank (10K, wbudowana podstawka i inteligentny wyświetlacz)

Took this on a week-long work trip and it doubled as a bedside charger thanks to the built-in stand, which I didn't expect to use as much as I did. The magnet snaps on solidly even through my thin case, though it does add some bulk to a pocket.

The smart display showing exact battery percentage is way more useful than I expected — no more guessing on my desk. It charges my phone through the case fine and the stand keeps it upright while I work.

The built-in stand is the feature I didn't know I needed — I prop my phone up on it while working and it charges at the same time. Ten thousand milliamp hours gets me through a full day of meetings without hunting for a wall outlet.
