Handheld projectors can be very useful devices when you need to project a large image on-the-go, but many of them lack enough brightness, resolution and battery life. California-based company AAXA Technologies has rolled out its P4 Pico Projector with the aim of addressing some of these issues - it offers 80 lumens of brightness, 75 minutes of battery life and can handle 720p videos.

Many pico projectors, such as the SHOWWX+ or MiLi Pro, feature only 10-15 lumens, which makes the P4's brightness quite impressive. The battery life should be enough for a business meeting, but alas, it's no good for watching a feature film. Utilizing TI's DLP technology, the P4 offers WVGA (854x480) native resolution and WXGA (1280x768) maximum resolution, thus 1280×720 (720p) videos are supported.

The unit displays images up to 80 inches, with a 2000:1 contrast ratio. There's a built-in 1W speaker, as well as a 3.5mm audio jack. Videos from external sources can be sent through VGA (mini-VGA) and composite A/V connectors, while connecting other external devices is possible via USB 2.0 and mini USB 1.1 ports.

It's lightweight enough to be comfortably used on-the-go, weighing in at 0.8 lbs (362 g).

Due to the fact that it runs Windows CE OS, AAXA describes its P4 Pico Projector as a "standalone mini-computer," provided that an input device is hooked up as well. A number of Win CE apps can be run, including media player, Microsoft Office Mobile, Adobe PDF viewer, or mobile games. Additional software and media files can be stored on 2GB of built-in storage, or using a memory card.

Bundled with tripod, remote control and a set of cables, the AAXA P4 Pico Projector is currently available online, priced at US$339.
