Product Description

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, 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.

Pros:
-Battery pack has a capacity of 13000mAh
-Small in size for this size battery pack
-USB ports have a combined max output of 3 amps and has PowerIQ so any device can be charged at max speed
-Battery pack charges at 2 amps using the micro USB port
-Built in LED flashlight (not bright but its a flashlight)
-Feels nice to hold and is easy to carry in my hand
-Can charge my iPhone 5 around 6-7 times
-LED power level system (4 LED's and each LED indicates 25% of the batteries capacity) (these lights are not that bright which is a good thing)

Overall, this is a great choice if you are looking for a battery pack, especially for the price compared to other listings that have the same battery capacity!

I was supplied a sample for test and evaluation, for free to keep, and I promised that my review is fair and honest.

First off let me say how impressed I am with this product - for real. Anker gave me this product in exchange for my honest feedback, but this thing is seriously unbelievable. It is incredibly small (4.1 x 3 x 0.9 inches) and very lightweight (13.3 ounces). I travel a lot so I am constantly on the lookout for something/somewhere to charge my devices whether on planes, out in the desert, in a cafe in Europe, on a long train ride, etc. I've found my new favorite. Even if I am just at home on the couch or lying in bed, I can have my power source close by so I am not constricted by a cord going to the wall. At 13,000 mAh this thing just does not stop. It holds an unsurpassed charge for longer than any other devices I've used. I've done some testing over the past few days. Here are the results:

1 full charge of the Anker Astro E4 13,000 mAh external battery lasted me three days using it solely:

*Charged my cell phone (Motorola Atrix) over night. The Astro E4 turns off when finished charging!
*Charged my friend's cell phone (Samsung Galaxy S3) for 2.5 hours during a movie at the theatre.
*Charged my Nexus 7 tablet over night.
*Charged my Motorola Atrix again last night to 73%.

*ALL before needing its first recharge!!*

My favorite features:
=============
*Dual power ports - one for 1 amp devices and one for 2 amp devices
*Can charge multiple devices at once
*Comes with MicroUSB, MiniUSB, and Apple iPad plugs with a sleek, well-made USB charging cable
*Awesome soft, fabric bag to hold the unit and its accessories
*Built-in LED flashlight!

Frankly, I wouldn't have thought to buy this for myself. I would have thought, "I can manage... I HAVE managed without this portable power plant of a battery so far..."
And I have, for years, managed.
But I received the E4 as a review unit (see disclosure below), and just threw it in my bag with my things when I went out.
And once you realize you've got such in incredible reservoir of power everywhere with you, well, let's just say your daily behavior that was previously subconscious to you... changes.

THE "SO WHAT":
If you feel you're making too many compromises for the sake of battery life (airplane mode, lowering the brightness, etc.), get yourself an external battery. Throw it in your bag, and forget about finding outlets in public spaces anymore.
Even if that doesn't happen for you often, it's perfect to take along on trips (use it for rechargeable camera batteries!), to the airport... you get the idea.

LOOKS
- Glossy black finish, with glossy charcoal for the front and back
- Sturdy/solid (read: not flimsy-feeling, almost seamless) plastic enclosure.
- Great propotions; fits in the hand well and the narrow shape tucks in bags well.
- Comes with a nylon mesh drawstring pouch that fits it perfectly.

==BENEFITS==

No need for outlets or long cables.
I think what surprised me the most was that I was finding it useful where I never would have guessed, because it never would have dawned on me. For example, I wanted to show my friend some videos on my iPad at his place, while we wait for another friend to arrive.

Charger will not charge. Charger just stopped functioning after 3weeks. Very disappointed in the lack of dependability and quality. Cost of return to high for value of charger.

I am compelled to amend my above review of this product based on very recent experience. I am motivated to so after a very pleasant and productive response from customer service of the Anker Company. Obviously they actually read my product review and reached out to me in a very timely manner. They listened to me and made arrangements to send me another charger immediately while apologizing for my inconvenience. I am more than willing to try this product again based on the company's confidence and support of their product.
