MagGo Power Bank (10K, Slim)

It slid into my jacket pocket and I honestly forgot it was there until my phone hit 10%. The magnet snaps on solid and it charged my phone back to full without me babysitting a cable. Ten thousand milliamps got me through a whole day of wandering around a new city.

This thing is barely thicker than my phone case and it charges without any cable, which is exactly what I wanted for commuting. The magnet holds solid even through my case, and 10K gets me through a full day of heavy use.

Snapped this onto the back of my phone at a theme park and it never budged all day. The slim profile means it slides into my jeans pocket without that ugly bulge other banks give me. Ten thousand mAh got me through two full charges of my phone.
