Vankyo Leisure 410 video projector review

Yes, I should have said 0.8 WATTS, not Amps.

Summary: For a sub $100 projector, it's very nice. Not super bright, but plenty of light with the drapes drawn or at night. Image quality is good (for the price) and certainly good enough to watch a movie with. OK quality from a computer, but hard to get the entire screen 100% in focus, but plenty good focus adjustment for videos or games. I tested the HDMI and SD card inputs, it also includes USB stick, composite and VGA inputs.

Fan is a bit noisy, included tripod head isn't rigid enough to support the projector without falling over, the remote mostly works well except for playing videos/photos from an SD card or USB stick (which need you to push the OK button on the projector body itself for some odd reason.)

It draws 45 watts when on, 0.8 watts when off.

To transcode movies so that they will play natively on the projector, I've found this FFMPEG command line to work for me (Ubuntu 20.10):
ffmpeg -i [input video name] -filter:a "volume=1.5" output.mp4
