GMLYE Ultra-Thin
The GMYLE Ultra-Thin power pack has a capacity of 2,500mAh, which is more than enough to extend your iPhone's battery life for a marathon session of Pokémon GO.
The GMYLE is only about 5mm thick and about the same width and height as a credit card, so you don't have to worry about finding space to carry this thing around.
It starts around $17 and comes with a built-in Lightning cable and even a Micro-USB cable, which saves you the trouble of keeping track of your charging cords for all your devices.
