This interesting accessory appears to be a case with a built-in secondary battery/dock combo that recharges your iPhone. The product’s web site is scant on details and the contact page says “We are looking for distributors for the United States and Europe,” so it’s tough to tell if and when you’d be able to buy one of these iPowerJackets.
UPDATE: Apparently you can buy one now on Amazon for $80. Thanks Joanna!
