The Details…
REVIEWER’S NOTE:
AnkerDirect has changed the product on this ASIN to a “2nd Gen” version. Many of the older reviews are reviews of the original first generation. This review has been updated to the second generation product currently provided here.
Edit February 25 2015:
Due to the increasing average size of smart phones, some terminology has been changed to better reflect the changing reality around the world.
This battery comes in a comfortable packaging with good instructions and a few interesting items. A double-sided mini-booklet advises how to get in touch with support in case of issues and solicits reviews in case of happiness. A short Micro USB cable is included as well.
Sadly, I have to touch on the raze item right here:
The construction of the USB cable is continuing the Anker standard of low quality. The outside sheath that covers the Micro USB connector should be the proper place to grab to remove the connector from a device, however just like in the Anker car power adapter, this sheath is not connected securely and slides down the cable instead. This exposes the connector to additional stress as the protective cover is gone and getting the connector out without sliding that protective cover down requires pulling on the cable itself, which is not good for it.
This is really secondary and overall not worth a star off, however Anker really should address this issue since it has now come up in two separate products that I have purchased from them.
What I would honestly love to see is some way to have things plugged into this without the cable sticking out so far. Phone and Battery, back to back with a low-profile connection to each would be truly-portable charging.

Battery for breakfast, lunch, dinner, and a late night snack…
Nobody can deny that the digital world of today is a power-hungry place. Charging stations have cropped up all over and it’s not uncommon to see folks’ phones plugged into the local wall sockets at coffee shops or bars or hotels. Phones and tablets are faster, brighter, and more powerful, but they eat batteries like mad. Even with an extended life battery clipped to the back or stuck inside, most people will find themselves running low at some point. That’s where an external charger battery comes into play.
Let’s start with some numbers and quick facts:
USB specification carries 5V (five volts). Officially, it carries 500mA (milliamps), or 0.5A. Running something at 500mA for one hour will consume 500mAh (milliamp-hours) of energy. Amps are a unit of DRAW – or “pull” – not “push”. If a battery has 1,000 mAh of capacity, it can have a 500mA draw for two hours. With 10,000mAh of capacity, it can support the same draw for 20 hours. The mA or Amp rating of a power supply (3A in the case of this external battery) is how much load (pull… remember?) it can take without overloading. It will not “push” that much through and kill things, however it can have problems if the load placed on it exceeds its capacity. So basically, a battery can provide energy for hours equal to its capacity in mAh divided by the average draw in mA.
Batteries are just a chemical reaction that makes electricity. More chemicals means more energy can be stored. But more chemicals also means a bigger battery and a heavier battery. Plus it’s important to consider that the Lithium-Polymer battery stores electricity at 3.7 volts, so there also has to be circuitry to change that up to 5V for the USB connector. More power takes more space and more weight. As a good example, the battery in an HTC One M7 is 2,400mAh, or a bit under 1/4th the capacity of this. Thus, this…

|great at first, but. ..then awesome,
update 03.02.14: sorry I didn’t update sooner. I emailed Anker and told them about the problem. They emailed me right away, asked for the model# and my address. They sent me another charger and didn’t make me go to the post office and pay to return the old one. Then they emailed me a week or so later to make sure I got it and to see if it was working properly. I emailed them back thanking them for their awesome c.s. and told them that it’s working great. I get 2 or 3 charges on my tablet or several on my phone with 1 charge. I not only would do business with Anker again, but I highly recommend them, their products and their c.s. is 2nd to none.

|Anker 10000mAh Astro3E battery pack,
Pros – Large capacity
Portable
Multiple different connectors for charging different devices
Attractive design/good construction
Cons – I wish it came with better way of organizing or keeping up with all the USB charging cord and connectors. Maybe slimmer battery design that would allow some kind of case built-in storage for the connectors? Or a self contained case of some kind that keeps up with the cord. I am thinking of solution…ahh wish I had that 3D printer now…any how the carry pocket that comes with it is not the best solution. Not sure this would be great daily pocket-able solution (look to the slim battery pack they offer). As with all battery packs the dilemma is between portability, size and capacity. For my needs I can keep this in backpack, travel bag but for a jean pockets or such slimmer less capacity battery would be better. You have to find what your needs are in this situation with regards to your battery purchase. I recommend this especially if you fly on long flights, travel frequently or have a high need for extra battery life on the go.
On a final note battery pack recharging is done via a laptop. This product does NOT come with a AC-USB adapter for wall charging. There is also a Anker astro3 which is different as far some output and features are. The astro3 comes with wall AC-USB adapter. I uploaded some photos so you can visualize the size compared to a Nexus.
Thanks for reading my review and I hope this information assists you.
