Product Description

A charging station for the palm of your hand. PowerIQ: Compatibility maximized. Not all charging ports are created equal. Standard ports only communicate effectively with particular devices, like Apple OR Android, often limiting their recharge rate. But with PowerIQ technology, each port intelligently identifies your device to speak its unique charging language. So plug in any brand or model and enjoy compatibility that doesn't limit your charging speed. A shot to your phone. When all you need is a boost the Astro Mini's got you covered. It holds enough juice to get you back into action without weighing you down. Add over a full charge to an iPhone, almost a full charge to your S5 or a full charge to most other phones. Primo construction. Each Astro Mini is built with dependability in mind. Premium chips, Samsung Grade A cells and a rugged aluminum shell ensure the highest possible performance and safety. Whether you're in the car, at a party or out on the trail, know you've got a battery that won't let you down. For optimal use. To start a charge, first press the power button. Compatible with all Apple and Android smartphones, tablets (including the Nexus 7) and other USB-charged devices. The iPod nano, Asus tablets, the LG G2 and some GPS and Bluetooth devices are not supported. To ensure complete safety and best performance, we strongly recommend using your device's original cable, a third-party certified cable (such as MFI) or our included cable. The included Micro USB cable is compatible with the Samsung Galaxy S5, Note 3 and other Micro USB 3.0 devices. To connect, insert the cable's Micro USB tip into the larger of the two connection ports on your device.

Enough juice for 1 full iPhone 5 or Galaxy S3 charge.

It's small enough to fit in a purse or your pocket & comes with a bag to carry your charging cord too!

I love that I can charge my phone on the go - as its battery always dies.

I got this product for my mom since she replaced her old Nokia with an iPhone 4s.
Of course battery life differs drastically between those models. As a result the phone would run out of juice most of the time.
Pros:
-Compact in size. (9cms length 2.2cms width)
-Sturdy aluminum body. (Always a good thing inside a purse)
-Bright silver color. (Easier to locate in a purse)
-Charges in less than 2 hours using a USB wall charger.
-Fully charged the phone twice on a single charge with juice left.
-Handy accessories pouch and cable included. ( mini & micro USB + iPhone plug)
-Auto cut off feature if not in use.

Cons:
-None so far.

Now we no longer worry about my mom's phone running out of charge in case of emergencies.
Highly recommended!!

I was excited to see such a great little product for such a low price. Yeah, it is not the most glamorous thing in the world, but I use it just like I would any other charger with the exception that I don't have to be near a wall outlet. I just toss this thing in my backpack. Cool stuff.

Update:

So, I had always had the problem of forgetting my cable at home. Also, my girl always wants to charge HER phone (an iPhone 5). I just found an awesome product that solves both of those problems, and doesn't cost too much more than this product.

It is called a Mana Mini: iSmooth Mana Mini 2600mAh Portable Power Bank - Retail Packaging - Black

If you are like me, then I recommend getting this product.

This is a very good product and serves a vital need to those who need to charge their device when away from a plug. The only thing that I initially missed in the directions was that you must press the button next to the USB slots before it will start charging.

I bought this product about six months ago, and was very pleased with it. The quality was great and it came with a travel bag and like 6 adapters for all the popular phone models. I showed my Dad and he wanted one (since he is a truck driver and on the road a lot), so I gave him mine and decided that I'll order myself a new one on my own time.

Well, after ordering from the same seller (and from the same Amazon page which indicates that it is the same item I purchased previously). I am extremely disappointed with the drop in quality. While Anker does offer my color varieties than previously, they exchanged the original travel bag with a small mesh bag, which doesn't feel the same and isn't large enough to hold the various adapters you may need plus the Astro mini itself. They also no longer include all the adapters for the popular phone models, so the only thing you get is a micro USB to charge the device (but you need an A/C wall convertor to charge it within a reasonable time).

I don't have a problem with needing a separate device to charge it via the wall, but removing all the adapters means you have to purchase a convertor for each type of phone which is a hassle (might not be rated to work) and will not fit in the travel bag. With my previous purchase, I've had at least separate occasions where I let my friends use my charger, because I knew that I had an adapter regardless of the phone. That is no longer the case, plus even if you bought the adapters, the travel bag isn't big enough to hold them, which hurts the portability of it.

I'm assuming the adapters aren't included because they assume you will have your original phone charger with you, and most phone chargers these days can detach via USB.

This device has a mind of its own. Recharge? Maybe. Charge my device? Not so much.

Totally unreliable.

I charged the device fully a couple of times, but it would shut off in the middle of charging my Droid Razr Maxx, often after just a few minutes. I tried several Micro USB charging cables, all of which work with my other devices, but the cable didn't make a difference.

Elegant design, technological fail.

Update: Within three days of receipt, I decided not to chance it and return the charger to Amazon. Coincidentally, The Anker Company reached out to me the same day to see if the product had arrived in time, and if I was happy with it. When I replied with the details of my dissatisfaction, they offered to replace it with a new one, no questions, no hassle. Although in the end I decided to proceed with the return, the company's customer service and follow through was outstanding.

Just got back from a business trip from Romania and this kept my Samsung S3 charged up for the complete 29 hours it took me to get home. Other than take offs and landings, the phone was never off - music, movies and reading books, calls at the airports. Previous trips would give me a dead phone in 6 hours. I even loaned it to an other passenger so he could top off his Ipad. For vacations or business travel, this is great. No complaints what so ever.

I received my charger in record time! I purchased two other similar chargers at the same time for my daughters because they insisted on one of the fashion colors. They claim to have the same strength as my Anker, but don't offer nearly the charging capacity! Theirs will only charge their phones to about 75% while my Anker charges to 100% and still has enough juice to bring it up to about 40% again. I will say that it charges faster if you don't let your phone get below 10%. The device comes with a convenient carry pouch and a multi cord to work with almost any phone so you don't have to carry an additional cord. It does not have the iPhone 5 attachment. The charger is about the size of a fat highlighter marker so it fits conveniently in your pocket or purse. This charger has saved me more than once already and I highly recommend it. You can't beat it for the price!!
