MagGo Power Bank (10K)

Took this on a weekend trip and it charged my phone from dead to full about twice before needing a recharge itself, which is exactly what I wanted from a 10K. It's a bit chunky in a pocket but slides fine into a backpack sleeve.

Ten thousand mAh gets my phone through a full day of meetings and navigation without hunting for an outlet. It's a bit chunky in a pocket, but it slides into my bag's side pocket fine.

The magnetic alignment snaps into place perfectly every time, so I don't have to fiddle with cables while walking around the office. It's slim enough to slip into my pocket, and it gave my phone a solid full charge before I even noticed the battery light blinking.
