In need of some extra juice for your iPhone 3G? The Incase Power Slider ($100) is by far the best solution we've seen for doubling the iPhone's battery life. This hardshell case features an integrated low profile lithium-ion polymer battery and an optimized power management system that together provide a continuous charge to the iPhone's battery. The Power Slider also has sync and charge capabilities and a 5-light LED battery gauge.
