Bonitor MP201 Pocket Projector
The Bonitor MP201 pocket projector is capable of projecting images in nearly any situation - with the ability to hold it in the palm of your hand, you can project a "big screen" image on almost any surface. I found the MP201 useful in mobile situations - such as in a car or while on transit on a plane and train - when used along with an iPod as the video source. The MP201 features a long-lasting battery and built in stereo speakers that are capable of producing relatively impressive sound levels. It is illuminated by a LED light source that is rated to last 30,000 hours - at 6 hours of use each day, that amounts to a 14-year life span. Available directly from the Bonitor web site for $249, the MP201 is a true plug in play device - while it does not have an on-screen menu or picture adjustment settings, it is capable of producing quality images many times the size of the average portable media player.
Audio Capabilities: The audio output of the MP201 is rated at 0.5W. While the audio output lacks any appreciable bass, the sound level that this unit can produce is beyond expectations for a projector in this size. The audio output is enough to overcome a moderate amount of ambient noise and would be useful when sharing videos with a small group. For larger group situations or where ambient noise is a factor, you will want to plan on using external speakers.
Battery Life: Bonitor rates the non-user accessible 2500mAh li-ion battery for 2 hours of continuous run time. In testing with a fully charged battery, the MP201 averaged a run time of slightly over 90 minutes. While not quite meeting the specified value of run time on battery power, this performance is significantly better - close to twice the run time - of similar projectors in this class. The MP201 power input utilizes a micro USB connector. Using a micro-USB cable connected to a laptop, I was able to charge the projector but was not able to operate the projector when connected to the USB port, likely due to the limited current available over USB.
The native resolution of 640x480 is above average for projectors in this class and helps the MP201produce images that are nicely detailed. The high fill ratio of the LCOS imaging chip makes individual pixels almost impossible to see even with large image sizes. The result is a very smooth and natural looking image.
Cost of Ownership: The Bonitor MP201 provides a fully functional display device that requires zero additional cost over the life of the unit - the LED life span of 30,000 hours equates to thousands of dollars in replacement bulb cost for standard projectors.
