Anker Astro Mini 3000mAh External Battery

Low-profile? Check. Convenient? You know it. Reliable? Of course. With the Anker® Astro Mini, gain access to stylish, portable power - all in the palm of your hand.


Anker Astro Battery

A Shot to Your Phone

When all you need is a boost, the Anker® Astro Mini's got you covered. Holds enough juice to get you back up and running without weighing you down (less than 3oz). Add more than a full charge - that's up to nine hours of talk time to an iPhone or more than 90 hours of audio playback to most other phones.

Anker Astro Battery

Undercover Power

The external battery of choice for secret agents, overnight campers, busy parents and those headed out for a night on the town. At the approximate size of a tube of lipstick, it slips easily into your bag, pocket or even your clutch (only 3.5in. long). Eliminate the bulk, but still be ready with a backup.

Anker Astro Battery

Primo Construction

As with all Anker® products, each Astro Mini is built with dependability in mind. Specifically, we incorporate premium microchips, Samsung Grade A cells and a rugged aluminum outer shell to ensure the highest quality possible to our customers. Whether you're in the car, at a party or somewhere out on the trail, know you've got a reliable battery that won't let you down.

Anker Astro Battery

For Optimal Use

- Compatible with all Apple and Android smartphones, tablets and other 5V input USB-charged devices. The iPod nano, Samsung and Asus tablets and some GPS and Bluetooth devices are not supported.
- To start a charge, first press the power button.

1 out of 5 eggsDoo doo

Pros: design

Cons: shame it doesn't hold a charge nor even when fully charged, discharge a high enough voltage to charge your phone. Fully charged, mine puts out 3.1 volts, yet phones require 5 volts. Go figure. It's useless.

4 out of 5 eggsExcellent charger

Pros: I bought this to use with my Apple iPhone 5s and could not be happier. I get more than one full phone charge from a complete charge. It does get a little warm when charging but this is no big deal. I find this product is perfect for traveling, especially in the air. Highly recommended - good value.

Cons: Gets warm when charging a device but this is not really a problem.
