Acer K330 portable projector


This small projector is bright and light

Small and light ; Brighter than most pico projectors

Brightness is still low ; Minor artifacting at native resolution

Acer's K330 is a slim and light LED projector, but it has a brighter lamp than most. It's bright enough for presentations or videos in most settings -- only bright rooms are a problem. We did notice a few image artifacts at its native resolution though.

Acer K330


The Acer K330 projector is only a little bigger and heavier than a palmtop, but it's a lot brighter, with a 500-lumen rating.

Smaller and lighter than standard lamp-based projectors. Brighter than pico and palmtop projectors.

Shows scaling artifacts (lines and patterns added to some screens) even at its claimed native resolution.

Review Acer K330 Projector


Projectors come in many sizes – from commercial behemoths and domestic shoebox-sized models, though to the palm-top variety, and the Pico projectors, which are super small compared to some of their contemporaries.

light, easy to use and relatively quiet

mediocre sound, sticky controls and no HDMI cable

All in all, the Acer K330 laptop projector is a wonderful little unit that if you are looking for a portable, reliable and easy-to-use projector, then it should certainly be on your short list.

Acer K330 Review


Weighs 2.9 pounds, with 500 lumens and a claimed 1280x800 resolution which put it into the "next generation" category of LED projectors...

Acer K330


Small and portable. Many input formats from HDMI, VGA through to SD cards and USB. Robust and durable (compared with conventional lamp units). Well packed and comes with lots of nice extras (case, remote etc). Easy to use and it hunts for input sensibly.

Not very bright. Acceptable in a dim room. Some "rainbow effect" BUT this is only when you move your head quickly and look for it; I thought I'd hate this but actually I don't notice. Focus shifts slightly as the unit warms up and a ceiling mount will...
