Anker introduces the second generation Astro3 external battery, now available at The flask-sized Astro3 packs a high-capacity 12,000mAh battery that can charge to up to three mobile devices simultaneously with its highest-in- the-industry 4A current capacity. The versatile external battery pack has three USB ports including a Smart Port that identifies the type of device that is plugged in and then adjusts to deliver its fastest charge speed. The second generation Astro3 is the first to feature a single port that can offer full-speed, fast charges to both iPad and the Samsung Galaxy Tab.

The two additional ports offer universal charging for Android phones at maximum speed and are also compatible with iPhones and other 5V USB-charging devices. The Astro3 can deliver six to seven full charges for most smartphones and offers a quick, energy-efficient power boost to keep you connected at all times.

The matte black, button-free Astro3 features a minimalist and intuitive design that complements your existing products. Simply shake the lightweight, compact device to start a charge or see the battery’s remaining power level. Small circular LED power indicators dial down so users know at a glance exactly how much juice is left.

“As part of our flagship line of Astro External Batteries, the new Astro3 is easy-to-use, affordable and bridges the Apple / Android divide to deliver truly full-speed charges no matter the device,” said Steven Yang, Anker Founder and Chairman. “To do this, the battery pack features a unique smart chip that adjusts USB pin signals to access and accommodate the connected mobile device’s true full-speed charging current.”

With an energy efficiency rate 10 percent higher than other external batteries, Astro3 uses smart chip technology to determine full charging speeds, delivering more than 50 hours of talk time for smartphones.
