Anker 2nd Gen. Astro3 - 12,000mAh External Battery

The all-new 2nd generation Anker Astro3 recasts the possibilities of mobile power. Keep multiple gadgets powered up better than ever, whatever your adventure.

Packed with Power

We figure, the more power, the better. Packed with 12,000mAh of juice, and featuring an energy efficiency rate 10% higher than the previous generation, the new Astro3 charges the iPhone six times and large-capacity phones like the Galaxy S4 almost four times. Keep multiple devices going yourself, and still have juice left to share.

The Faster the Better

Waiting was never fun, was it? That's why we created the new Astro3 with a smart port that detects USB pin signals to identify your device - whether Apple, Android, or even the Samsung Galaxy Tab - and charge it at full speed. With two additional ports, no need to wait in line either.

Double Take

Chic and minimalistic, the new Astro3 may feel reserved at first. But, a friendly "shake" reveals its warm inner light to display the power level or begin your charge. Generous, cool, and delightfully intuitive, the new Astro3 is perfect for your next adventure, or just the daily grind.
