PowerPoint presentations on laptop computers may become a thing of the past thanks to gadgets like the iPhone 4 Pocket Projector. The Pocket Projector is part projector and part backup battery.
The iPhone 4 Pocket Projector displays images up to 50" large, with a resolution of 640x360. The projector is powered by a powerful 15-lumen LED projector lamp. The Pocket Projector also contains its own speaker and features focus adjustment to ensure that your picture is never fuzzy.
Perhaps the greatest feature of the iPhone 4 Pocket Projector is the fact that it can be used as a backup battery. The device's 2100mAh battery can be charged using a USB cable and can power your iPhone when its not projecting movies or images. The Pocket Projector is available from Brookstone's online store.
