ASUS P3B battery-powered short-throw projector #1

800 lumens short-throw DLP projector. Will accept USB thumb drive, micro SD card, HDMI or VGA input. 1280x800 resolution. The battery life, when fully charged, is about 3 hours. Has a built-in speaker and stereo mini audio out. Note: this projector does not have an optical zoom lens. It can be mounted on a typical 1/4", 20 UNC threaded screw. The HDMI port on ASUS P3B #1 is currently working, but has had problems in the past. There is an HDMI -> VGA adapter included in the case that allows it to work at the same resolution through the VGA port.
