I've been looking for a good mass-device charging system for our family's iPhones and iPads for a while now, with surprisingly little available on the market. Several months ago, Griffin technology announced a new product that would help with this called the "PowerDock 5".
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 clear backrest. Each charging bay is roomy enough to accommodate your iPhone, iPod or iPad in their cases. An illuminated status light tells when PowerDock 5 is powered up and ready to charge.
The PowerDock 5 begins shipping this week, and will cost you about $100/unit.
