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

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.

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 3.5" long). Eliminate the bulk, but still be ready with a backup.
