Acer K138ST

 

The LED-based Acer K138ST has a relatively short throw distance and can project content from a smartphone via its MHL-enabled HDMI connection.

Compact. Lightweight. Can project content from a smartphone. Long lamp life. Short throw distance. Comes in soft carrying case.

Limited connection choices. Rainbow effect in video. Scaling artifacts visible at projector's native resolution.

Conclusion The Acer K138ST is compact and easily portable, and it has a relatively short throw for an LED projector, so you can position it close to the screen, and you can also display content from a smartphone attached to its MHL-enabled HDMI port....

Acer K138ST Projector review: A decent LED home projector

 

Projectors have multiple use applications from the office to a home theater, and the Acer K138ST is capable of living in multiple worlds. With a strong LED lamp and a 1280×800 resolution, this projector should fall into just the right spot for some...

Compact and portable. Nice carrying case included. Easy setup and easy to use

Speakers are weak, price point may be strong for a 720p projector

This is a nice projector for office or home use and great if you're not concerned with having full HD. Speakers are weak and we'd recommend external means for sound.
