Tablet & phone compatibility? Universal max-speed charging? Power-packed & portable? The reinvented Astro Pro2 has it all.

PowerIQ™ : Full speed charging. Every device, every time.
Not all USB charging ports are created equal. Standard ports only charge Apple OR Android devices at full speed. Our solution? PowerIQ™ technology intelligently identifies your device and speaks the language it needs for full speed charging. Coupled with an industry-leading 4.5 Amp output, charge multiple devices all at full 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.
