Griffin has announced that its PowerDock 2 Charging Station for the iPod and iPhone is now available. The PowerDock 2 features a brushed aluminum design and dual charging bays with the ability to charge any combination of two iPhone or iPod models at a time. The upcoming PowerDock 4 will offer four charging bays, and will allow for charging of up to four devices. Both include six Universal Dock Adapters for iPhone and iPod models that charge via USB. “PowerDock received overwhelming kudos at Macworld Expo this year and has been a much anticipated product since its introduction,” said Paul Griffin, founder of Griffin Technology. “PowerDock is the perfect solution for iPod and iPhone enthusiasts, as well as families with multiple devices.” The Griffin PowerDock 2 sells for $50 and is now available through Apple, and will soon be available on Griffin’s website; the PowerDock 4 will be available in July for $70.
