Following the Acer K10 pico projector, the Acer C20 micro projector shows a more serious side of Acer. About the size of a smartphone, this micro projector has USB and HDMI connections with a WVGA resolution. This micro projector is only 20 lumens though, but has 2000:1 contrast.
There are also composite and component audio/video inputs as well as stereo output for better sound. Rounding out the entire package includes microSD card slot together with a USB port that supports USB Slide Show and USB Multimedia for direct playback from a memory key.
A battery for this micro projector is good for up to 2hrs use in “ECO” mode (or 1hr in regular mode) and an optional remote round out the specs.
