Product Description

Color: Black

Capacity, charge speed, or portability? With the Anker® Astro 3E, you get all three. Who would've thought that 10000mAh could be so compatible, light, and sleek?

Four times the juice.
With 10000mAh of capacity, charge your iPhone 5 / 4 / 3GS / 3 four to five times (40 hours of talk time), your Galaxy S3 three times, or your iPad / iPad 2 once. That's more than 400% the capacity of most smart phones.

Get powered up...fast.
Plug in one device for 3A of output or two for 3A total. Special circuits built for Apple and Android let you charge your phones simultaneously at full speed.What's more, we included a handy travel pouch to store your cables and Astro all-in-one.

Simple, reliable power.
Designed to be functional and efficient - nothing else. At 0.59in thin, the 3E comes ready to serve as an unobtrusive, lightweight solution to your daily power needs. Four small LEDs alert you as to how much capacity you've got left.

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 USB charged devices with a 5V charge input. The iPod nano, Samsung and Asus tablets and some GPS and Bluetooth devices are not supported.

The Details...

This battery comes in a comfortable packaging with good instructions and a few extras (They gave me a bookmark... A bookmark? Really?). A zip bag contains the various adapter attachments: Apple 30-Pin, USB Mini, USB Micro, and a standard 5V Barrel connector. The other end of all of these adapter attachments is a smaller-than-normal barrel connector that plugs into the female barrel connector at the end of the spring cable. The other end of the spring cable is a standard USB A male connector, same as you would plug into a computer.

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.

I don't actually like giving 5-star reviews, and on this one I hovered over 4 stars thinking to myself, well ... what's actually wrong with it? What can I deduct a star for? It doesn't actually charge itself magically from the luminiferous ether, it doesn't fly or bake cookies, and it definitely doesn't impress the ladies. Maybe they'll work these features in.

I've just received it and used it a couple times, so maybe I'll find a serious problem with it in the future. But for now, I'm really impressed with the apparent quality and functionality of the device. I can't really find anything serious to complain about.

Make no mistake, this thing is not subtle. It's bigger and heavier than my Galaxy SII (a fairly large-screen phone), though the dimensions are comparable with the phone when my rubber case is on it. It's massive, like a plate of armor or a piece of a big stone tile, and feels nearly as dense and solid. At 37Wh of capacity and up to 3A of current, the size and mass is definitely justified though, and it's obvious that they didn't waste any internal volume with hollow spaces in the enclosure. It hangs heavy in your pocket, but then we knew that was the deal before we bought a 10 amp-hour auxiliary battery, didn't we?

As an aside, this is the kind of thing that seems to deserve its own new kind of clothing to carry and conceal it. Since it's mainly going to be tech geeks who are interested in carrying around so much gadget fuel, and nerds like me tend to have a pretty substantial anterior pelvic tilt from sitting in front of computers all the time, maybe there's a market for some kind of garment that will hide a device like this in the curvature of the lower back, providing an "outlet" through your clothing somewhere around the belt.

I read a lot of the reviews and despite some concern about the people who said they got what appeared to be used devices and in some cases DOA devices I took the risk. Risk 1 me 0. Device's button when pressed caused nothing to light up. Plugged it into an ac charger and all 4 lights just constantly started blinking. Let it charge for a few hours came back plugged in an iphone and got nothing. Button still didn't cause any status lights to come on. Returning for a refund.

***UPDATE***
I am adding 2 stars as appreciation for the customer support team at Anker who reached out to me after the negative review and offered to send me another unit gratis to prove the product's merits. The second unit was received quickly and is functioning so far as planned (I will note that it wouldn't push my iPhone 4s to 100% without some extra button pressing. Stopped around 96% then I had to push the charge button about 4 more times to get it all the way to 100%). Also note that this unit does work perfectly well with the Google Nexus 7. Went from nearly 0% to fully charged overnight using this unit. Also note that if you have problems with your device update your feedback here on Amazon. Their customer support team seems to be more tuned into the feedback here than their own support site which I opened a ticket with before ever leaving feedback and didn't hear from until a day or so later. I will return in 6 months time and rate this device higher if it continues to function as I would expect and doesn't experience any of the failures or other oddities that some have noted in previous reviews.
