This might look at first glance like a regular cover for your iPhone 4 or 4S. But the manufacturer has done something very clever, creating a slim DLP micro projector that slips onto your phone almost without being noticeable. Not just a fancy decorative gimmick, the 400-PRJ011 comes with a 2,100mAh battery, which charges in around five hours and then gives you 2.5 hours of projector usage time.
The projector itself has a 640x360 resolution and weights in at a compact and light 103g (3.6 oz). Though it might be compact and highly practical, Sanwa haven't sacrificed smart functionality. The projected screen size can go up 65 inches and with a range of nearly 3 meters. Plus, there are internal speakers and it can even become a charger for your iPhone once you turn the projector off, adding a neat 100% to your phone battery.
