The Optoma PK201 Pico Pocket Projector is marvel of modern miniaturization. It's a real working projector that's two and a half inches wide, less than 3/4 of an inch thick and just a hair over four and a half inches deep. Yet it can project an image that can measure from five inches to five and a half feet measured diagonally.
With its vivid 2000:1 contrast ratio you can project on a screen or just about anywhere. Next time you're on a road trip sit in the back seat and project a movie or play a video game on the seatback in front of you.
The LED light source is rated to last 20,000 hours. You'll never change the lamp in this projector. So how do you get a decent picture out of a pocket-sized projector? Texas Instruments has adapted its famed DLP projection panel system (the part that forms the image) to the requirements of this mighty mite.
The PK201 comes with a Li-On battery that's good for about an hour on a charge. You can recharge it using the included AC adapter or, at a slower rate, directly from the USB port. Of course you can always run on AC power if there's a socket nearby and save your battery power for when you really need it.
You can project from a wide variety of sources thanks to the PK201's 2.5 mm A/V jack.
The PK201 has 28 MB of its own internal memory and its microSD slot accepts cards up to 16 GB. That means you can bring along tons of movies, songs and photos right in the projector. And with an optional iPod kit, sold separately, you can project right from your iPod or iPhone.
The PK201 also projects NTSC and PAL video signals and 720p and 1080i high definition video.
And if you get tired of giving presentations or showing off pictures and movies play a video game. Imagine playing on a 66 inch screen from a device you can fit into your pocket.
