Portable projectors whether digital, ultra or overhead are often considered essential to the on-the-go business person on making presentations in unpredictable environments. New technology has afforded lighter portable projectors at cheaper prices.When shopping for a portable project consider: Size and weight. To truly be portable a portable projector should weigh less than 6 or 7 pounds. The smaller the portable projector, the easier it is to pack and transport. An ultra-portable projector should weigh less than 5 pounds. Brightness. A portable projector with more than 2,000 ANSI lumens is best to provide crisp images for areas with a lot of ambient light. Portable projectors with 1,500 to 2,000 ANSI lumens will do fine in areas with some ambient light. For the presenter in a dark room, 800 ANSI lumens will fit the bill. Connectivity. Obviously, the more connectivity ports the portable projector contains, the more flexibility you will have. Does the portable projector have a USB port or outlet for video? What about wireless capability? Resolution. Portable projectors offer a variety of resolutions: SVGA (800 x 600), XGA (1024 x 768), SXGA (1280 x 1024) or UXGA (1600 x 1200). The larger the resolution, the sharper the presentation. Compare portable projector prices and features Do some research to find the portable digital projector, portable overhead projector or ultra portable projector with the features that fit your needs and the price to match your budget.
