It doesn't take up much room, about the same as a single iPad. But it gives you a place to store and charge 5 iOS devices at one time, from a single power source. We think it's the perfect charging solution for small offices or work groups, or a family full of iPhone users. PowerDock 5 gives each tablet its own charging port and its own frosted backrest, and each charging bay is roomy enough to accommodate your iPhone, iPod or iPad in their cases. PowerDock 5 is optimized for iOS devices (iPad, iPad mini, iPhone, iPod touch, iPod nano), although our testing indicates that PowerDock's 5V (2.1 amp) charging circuitry will also charge most Kindle and Android devices. Many smartphones and tablets have unique charging requirements, so PowerDock may not charge your device as fast as you're used to. Make sure you check your device's manual for any special requirements.
