Astro2 9000mAh

Packed with Power

We figure, the more power, the better. Packed with 9000mAh of juice, and featuring an energy efficiency rate 10% higher than the previous generation, the new Astro2 charges the iPhone four to five times and large-capacity phones like the Galaxy S4 almost three 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 Astro2 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 an additional port, no need to wait in line either.

Double Take

Chic and minimalistic, the new Astro2 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 Astro2 is perfect for your next adventure, or just the daily grind.
