2nd Gen Astro Pro2, 20000 mAh Tablet & phone compatibility? Universal max-speed charging? Power-packed & portable? The reinvented Astro Pro2 has it all.

Compatibility maximized.
Not all charging ports are created equal. Standard ports only communicate effectively with particular devices, like Apple OR Android, often limiting their recharge rate. But with PowerIQ™ technology, each port intelligently identifies your device to speak its unique charging language. So plug in any brand or model and enjoy compatibility that doesn’t limit your charging speed.

Uber powerful.
20000mAh of power keep you and your gear going, and going - and going. Add 1000% more battery life to an iPhone, 600% to your large-capacity phone (like a Galaxy S4), or 130-300% to your tablet (depending on its battery capacity) - all away from an outlet. What's more, the added energy efficiency gives you 10% more usable power than the previous generation and many standard alternatives.

Brilliant display.
Interacting with the all-new aluminum-cased beauty couldn't be easier. The LCD simplifies everything - displaying the remaining power (with precision down to the percent), output, input and voltage selection.

For optimal use.
- Please use your device’s original cable or a third-party certified one (such as MFi).
- Compatible with all Apple and Android smartphones, tablets (including the Nexus 7) and other USB-charged devices. The iPod nano, iPod Classic, HP TouchPad, LG G2, Asus tablets and some GPS and Bluetooth devices are not supported.
