Product Description

Color: Black

A charging station for the palm or 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.

I use my phone a lot and I was always worried about my phone dying if I was going to be out all day, with this external battery, I no longer have to worry about that.

I bought both the silver one (as a gift) and a pink one for myself and we both LOVE IT.

The Anker Astro Mini is a nice small back-up power supply to keep your power-hungry iPhone running. I ran a test with my iPhone 5 to see just how much juice you could expect.

I drained my iPhone 5 down to 10%, then used the Astro mini to recharge it to 100%. The Astro still had some charge, so I drained my iPhone 5 down to 10% again, then used the Astro mini to recharge. This time I only got back to 40% charged before the Astro was done.
The way I look at it, you can get ~1.2 full iPhone 5 charges from one Astro charge. Not bad and just what I needed to keep running thru a long day.

I recharged the Astro from my computer USB port. It took ~ 6 hours to fully recharge (charging light turned off). It might charge a little faster with a plug-in charger, but you should plan on 6 hours (or overnight) to fully recharge.
The instructions are simple and the carrying bag is fine. There are a number of adapters for included charging cord. Unfortunately, the iPhone 5 “lightning” connector is not one of them. If the lightning connector was included, it would be a 5 star.

I bought it anyway and I've used it twice already. There's been two nights when I've forgotten to plug the charger into my Nexus 4 and I had class at 8AM the next morning. My phone was almost dead, but all I had to do was bring the Astro Mini with me. Carrying them both around while the phone is charging is easy. I put the charger in my back pocket and phone in the front pocket, while still connected. The spiraled cord is long enough to allow you to use the phone while the charger remains in the back pocket. It gives my phone a full charge in about 2 hours.

I use this primarily for travel with my Samsung Galaxy S3. On average, it takes about 5 hours to charge to capacity, and stores slightly more than one complete battery charge for the phone. I've been using it consistently when traveling, and while I do wish it stored more charge, for the size and price, it's been very useful.

EDIT:
Anker Direct saw my review and sent me a 5600MaH unit to keep, which I'll review separately, but I will mention here that it is really fantastic. This is one of the best customer service experiences I've had. They kept in touch with me throughout the process and even suggested I keep the smaller model. Really a fantastic company to work with, highly recommended.

I'm a UPS driver working very long hours and stream music and talk radio from my iPhone to my bluetooth headset to help me make it through these super long Christmas days. The problem was that my iPhone's battery would run very low later in the day. This is no longer a problem thanks to Anker, I just hook my phone up to the Anker battery pack and let it charge my phone back up. Every couple of days I just connect the battery pack to the USB port on my computer, let it charge back up and I'm good to go for 2 or 3 more days. I like this product so much I bought one for my son for Christmas as well!

I ordered my first Anker as I was going to a music festival, and knew that I would need it. Unfortunately, it didn't work. It didn't take any charge. The green light would come on indicating that it was fully charged, but when I plugged in my phone, it did not last longer than 30 seconds. I received a follow-up e-mail from Anker directly asking me about my purchase. I told them the issue that I had, and the circumstance that it had put me in. They had me test a few things, and determined that it was a faulty Astro. They immediately sent me a new one, and it works brilliantly. I love it! It charges your device in no time, and is very portable. I would just suggest making sure that your device works before heading out of town, or an event where it is needed. The Anker customer service was exceptional!!!

I bought this just before a trip I was taking because I thought I would need some extra power for my devices. It arrived, I charged it up, and packed it in my carry on luggage. At my destination I tried to use it to charge my phone, but it didn't seem to work. I was planning on returning it. When I got home I had an email from Anker wanting to know how it was. I told them my issue to which they promptly responded (and on a weekend). Turns out it was user error. The little light the tells you when it's charged is actually an on button. You need to push it before you charge your device. It will light up green when charging. While the button was not intuitive, the customer service was quick, polite, and fabulous. Just bought another one for my hubby since I know we will be supported.

This is an ideal battery for smaller devices like phones, mp3s, etc.

I recently moved to a big city and running errands all day without a car means I either have to make sure the phone is fully charged in the morning or buy coffee in order to borrow electricity from a cafe. This charger is pretty much the perfect size and weight for my situation, or any for that matter. A fully charged Astro Mini will replenish an almost-completely-drained iPhone 4S to 100% the first time and a little less than 50% the second time. Though it's always a good habit to charge your phone before bed...but on the rare occasions that you forget to or need to have battery consuming applications (like GPS or Bluetooth) running for a long duration, it's a life saver.

I took off a star for the following reasons:

1) The instruction states that "The red LED indicator will flash continuously while charging. The red LED indicator will TURN OFF AUTOMATICALLY when the Astro Mini is fully charged." I find it not being the case for me and it took me a couple times to realize that once mine is completely charged, my indicator will stop flashing and stay fully on instead of turning off. Not sure if mine is defective, or it is an error on the manual. However not a huge deal.

2) We were shown a retractable adapter cable with the package but I received one of those coiled ones instead. The retractable cable would be more useful for me because it is longer (and adjustable) so I can pull my phone out of my pocket without having to take the charger out as well or disconnect it. I understand that companies do not always control the type of accessories that their distributors include on their packages so I probably just happened to not get the one on top of my list.
