I was gifted this amazing little gadget by someone who has learned to expect my lack of cell phone battery life but refused to put up with it.

The Anker PowerCore 20100 Portable Charger has enough power in its little frame (12.8 oz) to charge the iPhone 8 up to eight times over before it needs to be charged again. And with it comes a micro USB cable, travel pouch, and lightning cable, so you're set for wherever you are when you find your battery life low.
