SaFPWR (http://www.safpwr.com) has announced the immediate availability and shipping of their new line of iPhone 4 battery cases: their “Milano” line, to customers and distribution channels.

The case uses a rechargeable 2200mAh smart battery integrated into the case. The Milano is now available for US$99.95.

What makes it unique from shell case only designs is that the SaFPWR iPhone 4 Battery Case has a second battery integrated into the case itself, says SaFPWR CEO Brett Nelson. He adds that what makes it unique from other battery cases is when the iPhone is inserted into the Milano protective case. It not only automatically connects with this second battery, but with the SaFPWR Advanced Energy Management Technology system.
