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 12000mAh of juice, and featuring an energy efficiency rate 10% above previous generation Astros and many current standard alternatives, the new Astro3 charges the iPhone 6 times and large-capacity phones like the Galaxy S4 almost 4 times. Keep multiple devices going yourself, and still have juice left to share.

World’s fastest.
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.
