Optoma PK102

Optoma Technology PK102

If you want a pico projector that can display bright and colorful presentations all by itself, the Optoma PK102 ($250 as of January 11, 2010) may be what you need. Weighing 4.4 ounces, the 0.6-by-2.0-by-4.1-inch PK102 is the smallest pico projector we've recently tested. Despite being roughly the size of a deck of cards, however, this model packs enough power for solo business presentations for small audiences under low light conditions. The PK102 has a brightness rating of 11 lumens (8 lumens in economy mode); delivers 20,000 hours of LED light; and has 4GB of internal memory for storing presentations, movies, video clips, and digital images. It uses Texas Instruments' DLP (Digital Light Processing) projection technology, and comes bundled with VGA, USB, and composite (RCA-type) A/V cables for connecting it to any device that has video signal output. To use the PK102 with an iPod or an iPhone, however, you'll need a third-party cable (not included). Or you can leave the cables behind, and use the PK102's built-in media player to project your presentations, photos, and videos. Depending on the brightness mode you select, its battery capacity is 60 to 90 minutes.
