We’ve all been there. You’re out having a good time or working hard, and then you realize your phone, tablet, or laptop just doesn’t have enough power to finish out the hour. Sure, you could plug in, but there isn’t even an outlet around, making it a very nerve-racking situation. For times like this, it’s always a good idea to have a power bank around, making it easy to get topped up without having to stop what you’re doing.
