Power banks – those handy dandy portable battery packs – aim to solve the problem of smartphones' unsatisfactory battery life. They do so by storing extra charge inside of an external battery, which you may connect a phone to using its USB or Lightning charging cable. And power banks come in various shapes and sizes. Some are big, heavy, and bulky, but hold enough power to recharge a smartphone multiple times. Others are built with portability in mind. They can't hold quite as much power, but compensate for this by being extremely light and pocket-friendly.
This post is about the latter type of power banks. The models we have here are all designed to make your life easier by occupying very little space in your pocket or carry-on luggage. Yet they can bring a dead phone back to life in a jiffy. Check them out in the slideshow below!
