The Gift: Mophie Juice Pack Air ($80; mophie.com)
Perfect For The Dad Who: Loves his cell phone just as much as you do
Why He'll Love It: Know what's pretty awesome? The iPhone 4 and the iPhone 4S. Know what's not awesome? When your iPhone 4 or iPhone 4S dies. But, thanks to this "juice pack," dad can recharge his phone on the fly without any messy cords and without plugging a bulky battery pack into it. The Mophie doubles as both a case and a battery recharging system for the iPhone 4 and iPhone 4S and it's a must-have for anyone with one of the latest iPhones. Just be warned: Buying him this means he'll have twice as much battery power to whoop on you in Words With Friends.
