I have a minor panic attack every time my phone battery life dips below 50% if I’m not sure of the exact moment I’ll be able to charge it again. This is especially tough when I’m traveling and on it a lot navigating around, taking pictures, etc. I don’t want to carry a charger (and outlet adapter in most foreign countries) everywhere I go, desperately looking for an outlet I can plug into when I would much rather focus on the sights and experiences surrounding me. So instead I end up reserving my phone use only for emergencies, and constantly do math in my head about how much battery I have left, and how soon I think I’ll be back at my hotel.
The minute my USB power bank (also called portable charger) arrived in the mail, I knew I was about to be saved a LOT of phone anxiety. The power bank I have is 2600 mAh and holds more than enough juice to fully charge my phone from dead. It’s small too, which is nice because I can throw it in my purse and have it on me at all times, just in case I need it.
There is one small annoyance about it. While it charges my phone at the same speed as my wall charger does; it takes a REALLY long time to charge the power bank. It can take up to several hours, so I usually charge it overnight. All in all though, I would say it’s the best $9 I’ve spent in a while.
