Until phones can handle a day of normal use without dying, there's the Kodiak Mini 2.0 Power Bank. It puts extra charging power within reach - in fact, right in your pocket - in an ultra pocketable, rugged format that hides in your hand and takes a beating better than a Hollywood stunt double.
Waterproof (IPX7) with the lid closed and water resistant (IPX6) with the lid open - dustproof, shockproof, and functional down to -4 degrees F, the Kodiak Mini 2.0 isn't just here to save your social life; it could, in theory, save your actual life in an emergency (like maybe allowing you to make a phone call). And since emergencies come in all sizes, from "OMG how many likes am I geting?!?!" to "How long do you think until they send Search and Rescue to look for us?" we're sure you'll find it handy.
In the event of a real crsis, like misplacing the bag of marshmellow's when it's time for S'mores, you'll also appreciate the included 5-LED flashlight with its 100-lumen High, 65-lumen Low, and flashy, "Over here guys!" Emergency Strobe modes.
Phone dies. $#!t happens. And from the looks of it, you have three choices.
Chocice is yours (psst. It's #3, trust us)
