Anker Astro Mini Black 3000 mAh External Battery 79AN3K-DA

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.

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.

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.
