The Pokemon Go sensation that's sweeping the country is getting people to exercise, forcing them to learn the metric system, and restoring Pikachu's pop-culture prominence. Unfortunately, by keeping trainers' phone screens lit, it's also draining their batteries at an astonishing clip. While there are a number of tricks players have found for extending their phones' battery lives, from lowering their screens' brightness to switching off the game's augmented reality feature, nothing is as frustrating as watching your phone die while you're tracking a particularly elusive Pokemon. No Pokemon Go player wants to miss a shot at Ditto because their phone pulled a Snorlax and conked out on them.

If you really want to pound the pavement to catch monsters and incubate eggs, you're going to need more than battery hacks. You're going to need more juice. By picking up a portable charger or a charging case, you'll be able to quickly top up your battery while you're on the hunt for that elusive Mew. Grab one of these gadgets and watch your Pokedex fill up.
