Pull out your big-pockets and don't expect something light, but this package provides plenty of power

«««««««««««««»»»»»»»»»»»»»
The Haze (Things to Consider)
«««««««««««««»»»»»»»»»»»»»
* Slightly larger than a large Smart Phone
* Substantially heavier than a large Smart Phone
* Charges more slowly than the power it supplies
* Will not charge low-power-draw devices due to Auto-Off function
* Charging this device draws more power than some chargers can provide
* Does not come with an AC power adapter to charge itself so charging off USB is a very long process

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.

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.

I purchased this item about 8 months ago. for my cell phone. I LOVED it. It would charge my phone 4 or 5 times without needing a charge. All of a sudden a month or so ago, it won't even give me 1 charge. After plugging in the phone and pressing the button, all 4 lights light up, then I get about 25% charge and it's dead.. press the button, no lights. I just contacted Anker and left comment. I hope they have a solution. If they do, I'll give it 5 stars.
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.

For those readers that are reading this review on the Item page, this review is for the Astro3E 10000mAh charger. Since Amazon mixes reviews with all different "variants" of a product, and this comes in multiple capacities, this makes it hard to separate reviews.

This product does what it advertises, and does it VERY well. It comes with a nice mesh case which I carry it in constantly, and a nice little coiled USB cord with a few tips. While these aren't compatible with every device I own, I use it mainly to charge my phone, which is MicroUSB and included.

Some devices I have tried charging:
- I own a Motorola Droid 4, and I have charged the phone from dead to full over 4 times on a single charge. Android and Apple ports work, but on the Android port, the Droid 4 actually charges FASTER than the stock plug-in charger. My phone does not seem to mind.
- An LG Ally charges on either port, but faster on the Android port.
- A Nintendo DS Lite (with a compatible USB cord) charges on either port.
- An iPod Nano 6th Generation charges on the Apple port. It does not respond on the Android port. I have charged this device from dead to full, and did lose enough capacity on the battery for it to register.

I will update this review with more results as I charge more devices. I'm going on a few flights in the next couple of months, so this charger will gets LOTS of use.

EDIT - Nov. 2014 It's been the better part of two years since I wrote the review that follows, and as it is sometimes bewildering to think about, this is actually a LONG time in the world of gadgets -- especially mobile electronics. Phones come and go, and the GS2 I wrote about has long since died and been replaced, for the moment with a Note3. Among my daily carryables, the Astro E3 has now been eclipsed in outline dimensions, but not in mass.

I'm pleased to report that this thing is *still* a part of my routine, it still lives in my back pocket (where no cell phone would survive a day of my life), and it still gets pulled out all the time to allow me to keep using my phone. I get approximately two full charges of my Note3 out of it, and it remains one of the fastest USB charging sources I own.

A couple minor notes from my experience with this device, one good and one thing I'm going to complain about for a bit. First, this product has what may be an unintentional but very intuitive feature that I've seen omitted or prevented in some other battery products -- that is, the ability to plug in and charge the battery while simultaneously it is discharging into another device. The Astro E3 charges at a lower rate than it discharges, so the result is a net discharge, until the other device is full. This is super convenient when your sources of USB power are limited. Just plug the Astro E3 into a power source, and then plug your other devices into it. In the morning, everything will be charged.

That is, everything unless you have a low-power device that takes a long time charging at a low current draw. Anker's design (which I understand is not unique) includes an arbitrary current threshold, below which it doesn't feel it's necessary to provide power.
