Take high speed charging technology on the go with the new 5100mAh Fast Charge Battery Pack. This battery pack allows you to charge devices compatible with Samsung Fast Charge at a much faster rate than traditional USB charging options.
The Mophie Juice Pack Air is a rechargeable external battery concealed inside of a protective form-fitting case for the iPhone 4S, AT&T iPhone 4, Sprint iPhone 4, or Verizon iPhone 4. It offers you the full protection of a hard-shell case while providing virtually twice the battery life of the iPhone 4S, AT&T iPhone 4, Sprint iPhone 4, or Verizon iPhone 4 alone.
The Mophie Juice Pack Air is the ideal case for the everyday 9-5er and for those whose day doesn’t always end when they leave the office. Lighter and thinner than previous generations, but packed with more power!
