Anker AK-79AN13K-WA rechargeable battery

Astro E4 13000mAh External Battery - White With such massive capacity, in such a compact package, the Anker® Astro E4 is perfect for flights, road trips, or just any time you’re away from an outlet.

Enough power to go around.
Marooned? In transit? Forget your OEM adapter? With the Anker® Astro E4, prolong your battery life multiple times, wherever you are. Holding enough power to charge a smartphone 3-6 times (depending on your phone’s battery size), keep your gadgets going for days and still have juice left to share.

Strong but never slow.
In addition to capacity, the Anker® Astro E4 sports two concurrent, high-speed ports. So whether you're charging an Apple or Android device, you'll get the most out of your technology. We've also included connective adapters to ensure compatibility with most devices.

Designed around the details.
Just because the E4 packs a punch, doesn't mean it can't look nice. We went with a smooth, ivory/ebony finish to keep you traveling in style. Simple, unobtrusive features, such as one-touch status LEDs and a built-in flashlight, give you everything you need out of a battery without sacrificing aesthetics.
