Slip your iPhone 4 into this ergonomically designed case (4.95 x 2.75 x 0.85 inches [HxWxD]) from i-ON and the rechargeable 1400 mAh battery that’s integrated into the iB-8 $59.95 (www.i-on-usa.com) automatically goes to work charging the iPhone 4’s own battery if it’s operating at less than 100%. As a bonus, i-ON states that the iB-8 charges the iPhone 4 2X faster vs. using a regular (500mAh) USB charger. Further, you can charge your iPhone 4 and sync it with iTunes without having to remove the phone from the iB-8. An LED status indicator built into the case’s backside, meanwhile, lets you visually see the power status of the case’s battery. To stop the battery from charging, just press the indicator’s button.
