CES? Have a gander at this. Xtrememac has just rolled out yet another rechargeable battery pack / protective case for Apple's iPhone 4, with this particular monster having a 2300mAh battery, an integrated kickstand and an on / off switch. The InCharge Mobile will go for $79.99, putting it in direct competition from the folks at Mophie. Next up is the InCharge Auto USB, which is a somewhat plain in-car USB charger that saves itself with ten watts of output -- plenty to juice up your iPad as it acts as the Road Trip Jukebox. The InCharge Auto Plus doubles it up with a second USB port, while the InCharge Auto AUX tosses in a 3.5mm auxiliary jack for easy connecting to one's line-in port. Those three will sell for $24.99, $29.99 and $49.99 in order of mention, and the trio should be available to ship right about... now.
