This is one of the new generation of serious “pocket” projectors. While the K335 is no match for most traditional lamp based portable projectors in brightness, it’s ability to put almost 700 lumens on the screen makes it a serious projector for many uses, and small classrooms could be one of those. Still it was a disappointing measurement considering the claim of 1000 lumens. But, as we have pointed out many times, solid state light source projectors tend not to be all that bright, so there’s more tendency, it seems to “exaggerate” a bit about brightness. The K335 is a DLP projector with a solid state light engine and WXGA – 1280x800 native resolution. It can handle higher resolutions including 1080p, through its HDMI input. Of note, the K335 has MHL HDMI support of MHL compatible mobile devices, be that a Roku stick, some android tablets, or a host of other devices.
Presenting from iOS 5.0 or newer (iPhone and iPads) or Android works with the occasional adapter and the appropriate app for those devices.
The K335 can even do 3D from computer sources, but not Blu-ray 3D (packed). For an educational environment that’s probably just fine.
Wifi is optional, and probably makes great sense with a true portable like this one.
