Dausen iPhone pico projector battery case at Computex 2012
 

It's not the first iPhone 4/4S pico projector battery case we've come across here at Engadget, but we spotted this little number at Computex 2012 and just couldn't resist sharing it with you. What makes this accessory a bit more unique is that it incorporates the latest in DLP technology from Texas Instruments. As such, it's capable of projecting a 640x360-pixel image up to 70 inches across with 1000:1 contrast ratio. The 2200mAh battery lasts about 3 hours on a charge an can even top off your iPhone in a pinch. Additional features include a built-in speaker powered by a 0.5W audio amplifier. We spent a few minutes using the pico projector and while it works pretty much as advertised, it clearly struggled with the harsh lighting conditions of the show floor. Stay tuned for pricing and availability, but don't miss our hands-on gallery below and our demo video after the break.
