The all-new 2nd generation Anker® Astro recasts the possibilities of mobile power.

Power through your day.
We packed 6000mAh of power into a candy-bar shaped pack ideal for grab-and-go use. What’s more, we realized an energy efficiency rate 10% above previous generation Astros and many current standard alternatives. This energizing combination charges the iPhone 3 times and large-capacity phones like the Galaxy S4 almost twice.

The faster the better.
Waiting was never fun, was it? That’s why we created the all-new Astro with a Smart Port that detects USB pin signals to identify your device – whether Apple, Android or even something else – and charge it at its true full speed (up to 2A).

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

For optimal use.
• For simultaneous, max-speed charging of your Astro and other devices, check out Anker’s new 25W 5-Port Wall Charger or 24W Dual-Port Car Charger.
• Compatible with all Apple and Android smartphones, tablets and other 5V input USB-charged devices. The iPod nano and some GPS and Bluetooth devices are not supported.
