(Updated for the 2nd gen, 2014 model)
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.

Color: Black 13000mAh Verified Purchase
So far it works as described. Easy to charge and has all the adapters to charge my toys. The one really bad flaw is an on/off button that is raised above the case. This means it tends to get turned on accidentally in a briefcase or suitcase. Anyone that travels frequently knows that on/off switches need to be sunken in the case or protected by a raised bevel.

UPDATE --->> I had to come back and give this device a fifth star, as much for the Customer Service as anything else. I have used it several times and it works great. In addition to that, the manufacturer has emailed me and Customer Service called me last night and offered to exchange this for the Anker 14400 which apparently has a more flush button. I declined because I really like the way this one charges but I was very impressed. They really seemed like they were not going to rest until I was completely satisfied. 5 stars for attitude!

UPDATED REVIEW: Anker 2nd Gen Astro E4 13000mAh Battery

Anker sent me the 2nd Gen Astro E4 battery to review as the original review was getting a bit dated. In summary, the 2nd Gen Astro E4 definitely improved on a few items that were problematic with original version. Even if you are not upgrading from the 1st Gen, I believe the improvements are still worth considering compared to other batteries on the market. Improvements compared to 1st Gen Astro E4:

- Slimmer (But Longer) Body: While the 1st Gen Astro E4 was wide and shaped like a portable hard-drive, the 2nd Gen version is shaped like a flat glasses case (or a fancy pen case). This shape is much easier to slip into a front/rear pants pocket (albeit a loose fitting pair of pants). Both version weigh about the same.

- Increased Efficiency to 86% (11200mAh Actual): As stated in the original review, no batteries ever hit their capacity but this one came fairly close. This updated version hit 11200mAh while the original version only reached 9200mAh. I was able to charge my Nexus 5 phone fully about 5 times or my Nexus 7 tablet about 3 times. This will be my go-to battery for extended trips away from an outlet. For those of you using Apple's latest iPad Air, this will charge it fully about 1.2 times.

- 3A Maximum Output: With the new PowerIQ technology, either of the two USB ports can now charge to a total maximum of 3A. There is no longer a need to remember which port is the higher output port. Anker also increased the maximum to 3A for newer devices that support this amperage, which is a nice upgrade from the 2A of the 1st Gen.

Color: Black 13000mAh
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!
