Review: Anker 2nd Gen Astro3 12000mAh Portable Charger Backup External Battery Pack



Overview : PowerIQ™: Full speed charging. Every device, every time.
Not all charging ports are created equal. Standard ports only charge Apple OR Android devices at full speed. Our solution? Triple smart port, powered by PowerIQ™ technology, intelligently identifies your device and speaks the language it needs for full speed charging. Coupled with an industry-leading 4 Amp output, charge multiple devices all at full speed.

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 six times and large-capacity phones like the Galaxy S4 almost four times.

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.

For optimal use.
- For simultaneous, max-speed charging of your Astro and other devices, check out Anker's new 25W 5-Port Wall Charger.
- To ensure complete safety and best performance, we strongly recommend using your device’s original cable, a third-party certified cable (such as MFI) or our included cable.
- Compatible with all Apple and Android smartphones, tablets and other USB-charged devices. The iPod nano, Asus tablets (not include the Nexus 7), the LG G2 and some GPS and Bluetooth devices are not supported.
