Optoma Pico PK320 Pocket Projector

The Optoma Pico PK320 Pocket Projector ($450 street) is the brightest pico projector we've tested, with a good range of connections including HDMI. It stacks up well against other pico projectors in connectivity, and has decent image quality but for one notable issue we encountered in testing. It's worth a good look if you're looking for a powerful pocket projector. The PK320 is rated at 100 lumens, and has a native WVGA (854 by 480 pixel) widescreen resolution. The projector is quite compact, measuring 1.2 by 4.7 by 2.7 inches. Using our postage scale, I weighted the projector at 0.5 pounds, while adding the power adapter brought the total weight up to just under a pound. The projector also can run off an included, removable lithium-ion cell that can last 90+ minutes in eco mode and 50+ minutes in standard mode, according to Optoma. It can fit in my pants pocket easily enough, though it takes up much of the room. This copper-brown projector has the look of a larger projector, with the lens near the edge of one of the long sides, as opposed to the \"light saber” appearance of many picos in which the beam emerges from the middle of the narrow end. The focus wheel is in front of the lens, and is tricky to use, even if you can avoid putting a finger into the light path.
