The all-new 2nd generation Anker® Astro recasts the possibilities of mobile power. 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? A smart port, powered by PowerIQ™ technology, intelligently identifies your device and speaks the language it needs for full speed charging - no matter your device. 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. 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 40W 5-Port Wall Charger or 24W Dual-Port Car Charger. • 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. • 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.
