Anker Astro E5 15,000mAh External Battery

With such massive capacity, in such a compact package, the Anker Astro E5 is perfect for flights, road trips, or just any time you're away from an outlet.


Anker Astro Battery

Enough Power to Go Around

Marooned? In transit? Forget your OEM adapter? With the Anker® Astro E5, prolong your battery life multiple times, wherever you are. Holding enough power to charge a smartphone 4-7 times (depending on your phone's battery size), keep your gadgets going for days and still have juice left to share.

Anker Astro Battery

World's Most Compact 15,000mAh Battery

Innovations in battery cell technology allow us to pack more power into less space – making this the most compact ever 15,000mAh external battery. In addition to portability, the Anker Astro E5 sports two concurrent, high-speed ports. So whether you're charging an Apple or Android device, you won't need to wait around.

Anker Astro Battery

Designed Around the Details

Just because the E5 packs a punch, doesn't mean it can't look nice. We went with a smooth, ebony/ivory 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.

For Optimal Use

- For simultaneous, max-speed charging of your Astro and other devices, check out Anker's new 25W 5-port wall charger or dual-port 24W car charger.
- Compatible with all Apple and Android smartphones, tablets and other 5V input USB-charged devices. The iPod nano and some GPS and Bluetooth devices are not supported.

5 out of 5 eggsAmazing

Pros: everything that it advertises is true. extreme long life, and can charge almost any device connected to it. i used it to charge my wifes iphone and ipad along with my Galaxy S5 while on a trip. and still had more juice left in it! the main thing about this is i used emulators on my S5 during my 10 hour flight, while she was watching movies/reading used up only 1 bar out of the 4(the lights indicate how much power is left, 4 lights total when all are blue its at full charge). I also use it for road trips which works better then my car charger does

Cons: none, i found no issue with this. did exactly what i wanted
