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.

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 9 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.
