A charging station for the palm of your hand. PowerIQ: 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. A shot to your phone. When all you need is a boost the Astro Mini's got you covered. It holds enough juice to get you back into action without weighing you down. Add over a full charge to an iPhone, almost a full charge to your S5 or a full charge to most other phones. Primo construction. Each Astro Mini is built with dependability in mind. Premium chips, Samsung Grade A cells and a rugged aluminum shell ensure the highest possible performance and safety. Whether you're in the car, at a party or out on the trail, know you've got a battery that won't let you down. For optimal use. To start a charge, first press the power button. Compatible with all Apple and Android smartphones, tablets (including the Nexus 7) and other USB-charged devices. The iPod nano, Asus tablets, 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. The included Micro USB cable is compatible with the Samsung Galaxy S5, Note 3 and other Micro USB 3.0 devices. To connect, insert the cable's Micro USB tip into the larger of the two connection ports on your device.
