Built for the iPad, this pocket pico projector allows you to have a larger screen on demand where you can watch videos at leisure and on a larger screen. Weighing less than 5 oz, the projector connects to the iPad’s 30-pin charging port and projects the required image in a 4:3 aspect ratio.
Banking on a 35-lumen LED, the projector is capable of images that go 6-inches to 60-inches diagonally and can be projected on surfaces at a distance of 8 to 78 inches, with a resolution of 640 x 480 pixels. The best thing about this one perhaps is that it does not draw its juice from the iPad battery, but relies on its own lithium polymer battery that can run for about two hours and can be recharged via USB. The projector can also work as a backup battery for iPhones. Costs $250.
