There’s a power shortage in your pocket. While our mobile devices offer convenience, they still have a significant flaw: The rechargeable battery never seems to last long enough. Whether you’re on a business trip or family vacation, the only way to make sure it can keep up with you is an external backup battery.

With that in mind, here are 12 great options that’ll give you serious power when you need it most.
