Anker Astro E5 Portable Charger

Whether you're attending a festival, hiking up a mountain, camping with some friends, or simply roaming a city for a day, having an extra charge for your phone is always a good idea. This is where the Anker portable charger comes in, capable of charging an iPhone 6S 5.5x, or a Samsung Galaxy S7 3x, this thing packs a serious punch for its size. We've tested it through a backpacking trip across Europe and two Tomorrowland festivals, and this thing keeps kicking. Be prepared, and keep your phone alive.

Available on Amazon for $40
