The Optoma PK101 Pico Pocket Projector is among the first of a new class of personal projectors to hit the market. It’s an ideal size for sharing images and videos from mobile devices (think personal media players, mobile phones, iPODs, PDAs, cameras and gaming consoles) with a small groups of friends. You can also have a large display while away from home without lugging a monitor. The shiny, piano black Optoma is pocket size small at 1.97 x 0.59 x 4.06 inches (50 x 15 x 103 mm) and a feather weight at 4 oz (114g) – with the battery in. Optoma’s pocket projector is based on Texas Instrument’s DLP Pico projection technology and has a HVGA (480 x 320 pixels) resolution.

The projected image can be from 6 to 60 inches (0.15 to 1.5m) with the projector positioned between 10 and 102 inches (0.25 to 2.6m) from the screen. There are limitations however, as the maximum brightness is only 9 lumens. Essentially, you need a low ambient light level to view any larger projected image clearly. Considering that this projector may replace the use of a portable notebook, which also cannot be viewed in bright light, this may not be such a problem for potential users. A tripod adapter is included so you can place the EP-PK-101 on a tripod for projecting. No keystone correction so you have to have align the projector square to the projection surface.

Contrast ratio is an important factor in picture quality and the Optoma PK-101 scores well with a 1000:1 figure. LED bulbs have a characteristically long life and in the case of this projector the rated life is an exceptional 20,000 hours.

The PK101 can be charged through a USB connection or an included AC power adapter.

Sound output is not a strong point with the mono speaker being only half a watt however, given the projector will be displaying multimedia from mobile devices it’s most likely a set of headphones, earbuds or mini speakers will be available.
